I build backend systems that don't break under pressure.

Over the past 2+ years, I've worked as a Backend Developer at Signovate Technologies while also taking on freelance projects for international clients — primarily in e-commerce, SaaS, and customer support verticals. My core stack is Node.js (Express, REST & GraphQL APIs) and Python (FastAPI), backed by cloud infrastructure on AWS (EC2, RDS, S3, Lambda, SQS) and databases including PostgreSQL, MongoDB, and Redis.

Alongside my full-time role, I've built and shipped production-grade systems independently — including ResolveIQ, an AI-powered customer support platform for D2C brands that automates ticket resolution using LLMs and RAG pipelines, designed for microservices deployment on AWS. I've also built a 3D Real Estate Platform with a Node.js microservices backend and spatial data APIs.

My freelance background means I've owned entire systems end-to-end: schema design, auth flows, deployment, monitoring, and async job queues. Multiple clients have converted from project-based contracts to ongoing direct engagements — which I treat as the real performance review.

What I bring to a backend role: Production API design (REST, GraphQL, async patterns, rate limiting, caching with Redis), secure auth systems (JWT, OAuth, RBAC), cloud infra on AWS, AI/LLM integration (Groq, RAG pipelines, agent memory systems), and seamless payment integrations (Stripe, Razorpay).
