About this gig

Stop letting technical debt and slow APIs bottleneck your business growth.


I am a Senior Backend Architect with 6+ years of experience engineering, scaling, and operating mission-critical systems across Fintech, E-commerce, and EdTech. I specialize in breaking down rigid monoliths and building high-performance microservices using NestJS, Go (Golang), and TypeScript.


What I Can Do For You:

  • Microservices Migration: Safe, zero-downtime extractions to Kubernetes (GKE) or AWS.
  • Enterprise APIs: Secure, fully documented backend systems tailored to your business logic.
  • Performance Engineering: Optimizing queries and refactoring logic to reduce API latency by up to 90%.
  • System Observability: Datadog implementation to track errors and optimize cloud costs.


The AI-First Advantage: I leverage an AI-augmented workflow to deliver enterprise-grade code and robust testing at a velocity traditional developers can't match.


Important: Please send me a message before ordering so we can discuss your specific technical roadmap!
