Senior Backend Developer | Golang, Node.js, Microservices | AI/LLM

100% Job Success · Top Rated · 3,400+ hours and $100K+ earned on Upwork. I build Go and Node.js backends that hold up in production — distributed systems, gRPC microservices, and AI/LLM pipelines. My recent work is multi-tenant platforms where correctness matters: healthcare logistics on Go, gRPC and Google Cloud Spanner; international trade and fulfilment on Go and NestJS; a crypto platform where I led a backend team of 8. The common thread is systems that have to stay correct while integrating with things outside your control. WHAT I BUILD • Go and Node.js/NestJS microservices — gRPC internally, REST and GraphQL externally • Event-driven architecture and CQRS — Kafka, Postgres outbox patterns, Elasticsearch read models • Third-party API integrations that survive contact with reality — webhooks, polling reconciliation, retries, idempotency • AI/LLM systems — RAG pipelines, LangGraph agent workflows, vector search with Qdrant • Cloud infrastructure — Kubernetes and GKE, AWS, Docker, CI/CD, zero-downtime deploys AI-ASSISTED DEVELOPMENT, WITH A REVIEW LAYER I ship fast with AI coding agents, but I don't merge on green. The agent that writes code never reviews it, and for anything touching permissions or data isolation I verify by deliberately breaking the code to confirm the tests actually catch it. A test suite that has never been proven capable of failing is worth nothing — and that's how most AI-written code passes review while being wrong. If your codebase was built quickly with AI and now needs to be production-ready, that's work I do often. TRACK RECORD • Led a backend team of 8 engineers on a platform that processed $2M+ in revenue • Owned core services in a 40+ microservice trade platform, including Maersk and Seaboard Marine integrations • Built Go services on Cloud Spanner handling multi-tenant trip lifecycle and eligibility flows, plus four vendor API integrations • Rebuilt core interfaces of a language-learning platform serving 310,000+ users • Designed smart contracts and backends for a token ecosystem (~40M supply, ~2,700 holders) • Taught advanced Node.js and backend architecture as a university lecturer WORKING WITH ME You get a senior engineer directly — no agency layer, no handoffs. My background is a law degree before engineering, which shows up as unusual patience for edge cases, access rules, and the requirements nobody wrote down. Based in Georgia (GMT+4): full overlap with European hours, mornings for US clients. Send me your brief and I'll tell you how I'd approach it — including what I'd push back on.
