Senior Backend Engineer

I'm a Senior Backend Engineer with 9+ years of experience building scalable distributed systems, real-time trading infrastructure, and blockchain integrations. I specialize in designing high-throughput APIs, event-driven architectures, and DevOps pipelines that power mission-critical platforms. I'm currently freelancing — building backend systems and self-hosted Kubernetes platforms for clients and early-stage teams.

Featured Projects

01 · Brunch

Escrow-Backed Freelance Marketplace

A full-stack marketplace where clients and contractors transact safely behind milestone-funded escrow — funds are held on-platform and released only when a milestone is approved. Spans a Next.js frontend and a Go API, with real-time chat, live job boards, and a containerized CI/CD pipeline shipping to Kubernetes.

↗ Live Site

Key Achievements

Designed the escrow ledger and contract lifecycle: jobs → offers → milestone funding → release/dispute
Built secure session auth with short-lived JWTs and rotating refresh tokens, transparently refreshed at the edge
Added 1:1 client–contractor messaging over Agora with presence, typing, and unread state
Shipped live updates (job board, notifications) via Redis-backed WebSockets
Authored a Gitea Actions pipeline: native multi-arch (amd64/arm64) Docker builds, test/coverage gates, and gated Kubernetes rollouts
Enforced clean layering (thin handlers, service-owned business logic) with unit + E2E coverage
