About this gig

I'm a backend developer with 7+ years of experience building scalable, production-grade systems for B2B and B2C platforms. My core stack is Node.js, NestJS, TypeScript, and PostgreSQL. What I can build for you: - REST and GraphQL APIs with clean, maintainable architecture - Multi-tenant SaaS backends with role-based access control - Database schema design and query optimization (PostgreSQL, MySQL, MongoDB) - Secure authentication (JWT, OAuth, 2FA) and payment integrations (Stripe, Plaid) - AI/LLM integration (OpenAI, Gemini, Claude) into production pipelines - Legacy system migration and refactoring - Docker containerization and AWS deployment I have delivered projects across logistics, healthcare, real estate, fintech, and advertising - always owning the work end to end, from architecture decisions to deployment and client communication. Clear communication, clean code, and reliable delivery are my priority. Let's discuss your project and I will help you build a backend that actually scales.
