Microservices Jobs

I have already designed and implemented a complete event-driven microservices backend system for a hotel booking platform, and I am now enhancing it to a production-ready solution with advanced AI capabilities. The system is built on a scalable microservices architecture with independently deployable services such as User, Hotel, Booking, Payment, Notification, and Rating. It uses Apache Kafka for asynchronous communication and follows an event-driven saga pattern to handle workflows like booking and payment with reliable state transitions (PENDING → CONFIRMED/FAILED). The backend is developed using Spring Boot and Spring Cloud, including: * Eureka Server for service discovery * Spring Cloud Gateway for centralized routing * Feign Clients for inter-service communication In additio...

My production Kubernetes cluster needs hands-on assistance migrating the networking layer from its current, rather intricate CNI to either Cilium (eBPF with WireGuard) or Calico with WireGuard encryption. The overriding goal is a seamless, zero-downtime cut-over while preserving all of our existing custom NetworkPolicies—east-west, ingress, and egress traffic must continue to behave exactly as it does today. Scope of work The engagement starts with a deep-dive into the present topology, routing rules, and policy objects. From there, a step-by-step migration playbook and rollback plan must be crafted, executed first in staging, then in production. Once live, I need empirical data that compares both solutions: latency, throughput, CPU and memory overhead, and encryption overhead und...

I already have a Windows-based .exe that simply wraps a Spring Boot jar; that jar contains virtually all of the middleware logic connecting my local system with an external service. What I need now is a developer who can transform that single-file setup into a fully-fledged, scalable server running in the cloud. Point to me note - i want that spring boot server working as it is same no chnages only chances main sevrer inside it and make sure jar works with that server same to same as they work with orignal ones You’ll receive: • the original Spring Boot jar (inside the exe) • my full assistance and domain knowledge whenever you need it Scope 1. Unpack or otherwise extract the jar so the project can be built, tested and version-controlled normally. 2. Refactor or re...

I need the backend of our new payment platform built first. The immediate goal is a Spring-based microservice (or small set of services) that processes bank-transfer payments end-to-end. Please design the services around clear REST endpoints, document them with Swagger / OpenAPI, and make sure responses are clean JSON (XML only if a partner specifically requires it). Key points you’ll work on: • Spring Boot, Spring Cloud, Spring Security where appropriate • Bank-transfer payment flow: create transaction, verify funds, confirm settlement, emit events • Kafka or another reliable MQ for event propagation • Container-ready code: craft Dockerfiles, helm charts or Kubernetes manifests so I can deploy straight to our cluster • Liquibase-based migrations, ...

I’m in the closing stretch of a .NET Core microservice project and need an extra set of experienced hands to get us over the line. The architecture is already in place and running in containers, but several new endpoints and service refinements still have to be coded, tested, and deployed. Your focus will be pure development inside the existing Dot net Core microservices: writing clean C# for REST endpoints and message-bus consumers, extending EF Core queries, and ensuring every change sails through our Git- and Jenkins-based CI/CD pipeline. Once the code is committed you’ll containerise it, update the Helm charts, trigger the build, and keep an eye on Kibana to confirm the logs are healthy. Gatling drives our load tests, so any change must survive that suite before we call it...

AI Agent Platform (Build Brief) About us HOTR is a creator management agency. We manage a roster of 15–19 digital content creators (£100k–137k/month gross) with a team of ~15 (operations, customer support, marketing, a ~10-person messaging team, and finance). We want our own private, cloud-hosted AI assistant for the agency — built on our infrastructure, owned entirely by us. What we need (v1 scope) A web-based chat bot with two specialist AI agents: 1. Acquisition agent Helps run our creator-signing pipeline: Track prospects and their stage (contacted → pitch sent → follow-up → signed / lost) Flag stalled leads (our biggest leak: prospects go cold after the pitch with no follow-up) Draft outreach and follow-up messages in our tone of voice Answer ...

Experienced Java Spring Boot Developer & Mentor Needed for Hands-on Real-World Project Training I am looking for an experienced Java Spring Boot developer who can mentor me through hands-on learning by building real-world demo projects together.

I need a full, production-ready fork of the open-source Signal project, re-architected as a set of container-friendly Go microservices. The goal is to keep the rock-solid end-to-end encryption that Signal offers while gaining the flexibility, horizontal scalability, and deployment speed that a Go-driven service mesh provides. Project Overview, We are building a next-generation secure communication platform based on the open-source Signal ecosystem. Our goal is to create a production-ready platform that supports millions of users while preserving Signal's proven end-to-end encryption. We are looking for senior engineers with experience in distributed systems, Go, Java, cloud infrastructure, and large-scale backed development. What do you want to add to…? Technology Stack &bul...
