I am a versatile and experienced scientific consultant with a vast array of interests spanning various domains, including health, technology, and trade. My academic background is rooted in molecular biology, which allows me to bring a unique perspective to my work. As a freelancer, I specialize in providing a wide range of technical writing services, catering to diverse needs in the industry. Among the forms of technical writing I excel at are crafting comprehensive white papers that delve deep into complex topics, creating engaging and informative ebooks, conducting meticulous meta-analysis reviews, composing insightful case reports, and summarizing presentations with clarity and precision. I am also adept at editing content to ensure accuracy, cohesiveness, and readability. Beyond writing, my expertise extends to consultancy, business, and market research-related activities. Leveraging my knowledge and experience, I offer valuable insights and strategic guidance to clients seeking to make informed decisions in their respective industries. I hold a Ph.D. in oncology, where I specialized in the development of cancer medicines. Through my postdoctoral research, I honed my skills in this critical area of medicine, gaining a deep understanding of the intricacies involved in combating cancer. My journey through academia has also equipped me with a comprehensive understanding of patents and the intricacies of knowledge transfer, an invaluable asset in today's competitive landscape. Within the life sciences arena, I have contributed extensively to the literature, authoring book chapters and research papers, including rigorous systematic reviews. My dedication to delivering high-quality content has earned me recognition, and I was contracted by Athla LLC to produce technical medical articles. This project was particularly exciting as it involved the creation of a platform for "knowledge automation" through the utilization of medical records, specifically Electronic Health Records (EHR) and Electronic Medical Records (EMR). My success as a technical writer and consultant is attributed to my meticulous attention to detail, effective communication skills, and an unwavering commitment to providing value to my clients. I take pride in my ability to distill complex information into accessible and engaging content, ensuring that my reports are comprehensible to both experts and non-experts alike. Moreover, I believe in the importance of active listening, as it allows me to fully grasp the unique needs and goals of each client. This approach enables me to tailor my services to align with their specific requirements, further enhancing the overall quality of my work.

Over the years, I’ve worked across a range of stacks—React, Next.js, Angular, Python (Flask, Django), ASP.NET, Node.js, and Vue—often blending them with cloud platforms like AWS, Azure, and Firebase to deploy robust solutions. Whether it’s building sleek front-end interfaces or architecting back-end systems that handle thousands of requests per second, I take pride in making products that don’t just function—they perform. By 2022, I was leading full-stack projects using the MERN and MEAN stacks, helping startups launch MVPs in as little as 6 weeks. But I didn’t stop there. As demand grew for smarter, more adaptive systems, I began integrating AI into the products I built. I started with OpenAI’s GPT API, using it to power dynamic customer service bots. Then came automations: workflow engines built using tools like n8n, Make.com, and Zapier that helped businesses cut hours of manual work each week. One project I’m particularly proud of involved building an AI-powered concierge for a travel platform. The bot not only understood user intent from messy input but also remembered returning users, supported multilingual interactions (English + Mandarin), and triggered real-time booking workflows via a custom Node.js backend. What once required human agents was now fully automated—saving the client over 40 hours of support time each week. I’ve also containerized complex systems using Docker and orchestrated multi-service deployments, ensuring they remain stable under load. From crafting admin dashboards with React + Tailwind to deploying .NET APIs on Azure for enterprise clients, I’ve worn many hats—and enjoyed the variety. But beyond the tech, what drives me is problem-solving. Whether it's debugging an edge case at 2 a.m. or streamlining an onboarding flow to reduce churn, I thrive at the intersection of logic and creativity. I don’t just build for today—I build with an eye on what’s next. If you're looking for a developer who can combine engineering precision with creative insight to deliver solutions that are both smart and scalable, I’d love to connect Let’s build what’s next—together My Skills Frontend Development: React, Next.js, Angular, Vue.js, Tailwind CSS, HTML5, CSS3, JavaScript (ES6+), TypeScript Backend Development: Node.js, Express.js, Python (Flask, Django), ASP.NET Core, PHP Full-Stack Frameworks: MERN Stack, MEAN Stack Cloud Platforms & Deployment: AWS (EC2, S3, Lambda), Microsoft Azure, Firebase API Development & Integration: REST, GraphQL, third-party API integrations AI & Automation: OpenAI GPT API, n8n, Make.com, Zapier, custom workflow automation Databases: MySQL, PostgreSQL, MongoDB, Firebase Firestore DevOps & CI/CD: Docker, Docker Compose, container orchestration, GitHub Actions, Azure DevOps

I have spent the last 6 years doing one thing really well: making small businesses look so credible that their customers stop comparing prices and start reaching for wallets. That is not a tagline. That is what happens when your logo, your website, and your packaging all tell the same story before a single word gets read. I am Wania. I design brand identities and build websites for founders who are done looking like they are still figuring it out. My Shopify rebuilds have pushed DTC brands into six-figure months. One packaging redesign I shipped last year lifted in-store sales 42%. A recent ad creative campaign cut client CPC by 31%. These are not vanity metrics. These are the numbers that keep lights on and teams hired. Here is exactly what I bring to your project: Brand identity that actually sticks. Not a logo you will want to replace in six months. A full visual system that feels inevitable, like it could not have been any other way. Websites that sell while you sleep. WordPress, Shopify, Squarespace, Wix. Mobile-first, SEO-ready, PageSpeed green. Built for the algorithm and the human. Landing pages and funnels engineered for conversions. Wireframe to launch. Every button placement backed by behavior data. Every headline tested for clarity, not cleverness. Social and ad creatives that earn their keep. Thumb-stopping graphics designed to cut acquisition costs and increase return on ad spend. I do not do templates. I do not do "that looks fine." I do not disappear for three days mid-project and come back with something that misses the brief entirely. What I do is show up, challenge assumptions that are costing you money, and hand over work that performs from day one. If that sounds like the kind of partner your project actually needs, send me a message. Tell me what you are building. I will tell you exactly how I would make it impossible to ignore.
A Web Crawling Developer builds automated programs that systematically browse websites, extract structured data, and deliver it in usable formats for analysis, monitoring, or integration into business systems. Hiring a skilled web crawling developer turns scattered online information into reliable datasets that power pricing intelligence, market research, lead generation, SEO audits, and machine learning pipelines.
A web crawling developer designs, builds, and maintains crawlers and scrapers that navigate websites at scale. Crawlers discover and traverse URLs across domains, while scrapers parse the underlying HTML, JSON, or rendered DOM to pull specific fields. The developer handles the full data pipeline, from request scheduling and proxy rotation to data cleaning, deduplication, and storage.
The commercial value is direct. Clean, structured web data feeds price monitoring dashboards, competitor tracking, sentiment analysis, real estate listings, job aggregators, e-commerce catalogs, and research datasets. A capable web scraping developer makes the difference between a fragile script that breaks weekly and a production-grade crawler that runs unattended for months.
Engagements with a freelance web crawling developer typically produce one or more of the following:
Strong candidates show fluency across the standard scraping stack. Look for direct experience with:
Adjacent skills that often appear on the same profile include data engineering, ETL pipeline development, API integration, Python backend development, and machine learning data preparation.
Web data extraction is used across nearly every digital sector. The most common use cases include:
The right hire combines coding skill with practical experience handling real-world scraping obstacles. Strong signals to look for include:
Useful interview questions to copy and use:
Freelancer.com gives you access to a global pool of web scraping experts, data extraction engineers, and Python developers with proven crawler-building experience. You can review portfolios, completed project counts, client reviews, and verified skill tests before you shortlist. Clients set their own budgets and receive competitive bids, so you control scope and cost while comparing approaches from multiple developers in parallel. Freelancer.com's Milestone Payments hold funds securely and release them only when you approve delivery, which protects both sides during multi-stage scraping builds.
Hiring the right web scraping developer comes down to a clear brief, careful bid review, and evidence-based final selection. The steps below walk through how to source, evaluate, and award a web crawling project on Freelancer.com so you end up with a reliable crawler and clean data, not a brittle script.
The project brief is the single biggest determinant of bid quality, because it filters for developers whose experience genuinely matches your scraping use case. A vague brief attracts vague proposals; a precise brief attracts developers who can quote a realistic timeline and approach. Head to the
Bids are short proposals, not just price quotes. They reveal how each developer interprets your brief, what scraping approach they propose, and what they consider realistic for timeline and infrastructure. Read carefully and shortlist candidates whose understanding of the work matches your requirements.
The final decision combines proposal quality with profile evidence. Look beyond a single impressive sample and assess consistency across past scraping projects, because reliability matters more than flash for crawlers that need to run unattended.
A simple single-site scraper with clean HTML can be delivered in a few days. Multi-source crawlers, JavaScript-rendered targets, or pipelines with anti-bot handling and database integration typically take two to six weeks. Ongoing maintenance is common because target sites change their structure over time.
Scraping publicly available data is generally permissible, but legality depends on the target site's terms of service, the type of data, and applicable laws like GDPR or CCPA. A professional web crawling developer will respect robots.txt, avoid scraping personal or copyrighted content without permission, and advise on compliant approaches. Always confirm legal boundaries with your own counsel for sensitive use cases.
A crawler discovers and traverses URLs across one or many websites, mapping their structure. A scraper extracts specific data fields from individual pages. Most real projects combine both — a crawler finds pages worth visiting, and a scraper pulls the structured data from each one.
Yes. Experienced developers use headless browsers like Playwright or Puppeteer to render JavaScript, handle authenticated sessions, and interact with dynamic elements. These targets take longer to build for and require more careful maintenance than static HTML sites.
Both options are common. Some clients want delivery of the source code only, while others ask the developer to deploy the crawler on AWS, Google Cloud, or a managed service with scheduling and monitoring. Specify your preference in the brief so bids reflect the right scope.
