I build production backend systems, AI agents, and the infrastructure to ship them
I am a backend developer with about a year of production experience in Node.js, NestJS, and TypeScript. I build REST APIs and real-time systems, design and ship Generative AI features and AI agents that use LLMs, tools, and memory, and I own the DevOps side too, from Docker and CI/CD to deploying and running services in the cloud.
- 🧠 Build Generative AI and agentic AI systems with LLMs (OpenAI, Anthropic, Gemini), tool/function calling, and background processing
- ⚙️ Strong backend engineering: REST APIs, PostgreSQL, Prisma, Redis, queues, WebSockets
- 🚢 Hands-on DevOps: Docker, CI/CD pipelines, Nginx, AWS, DigitalOcean, Linux
- 🧩 Comfortable with multi-tenant SaaS, auth/RBAC, and clean modular architecture
- ⚔️ 700+ DSA problems solved on LeetCode, and ICPC 2025 regional participant
