I’m a B.Tech CSE graduate targeting SDE-1 / Software Developer roles, with a strong foundation in DSA, OOP, and System Design. I build clean, scalable code and pair it with hands-on work across full-stack client applications, AI-driven platforms, and real-time backend systems.

As a Freelance Full Stack Developer (LMT Furniture), I designed, built, and deployed a full-stack e-commerce platform from scratch in 3 months. I implemented a hidden, JWT-protected admin panel, fixed critical production bugs across the admin panel and image/enquiry flows, and independently handled end-to-end deployment (server, database, custom domain, and both frontend/backend) to deliver a live product at lmtfurniture.in.

Across projects, I focus on reliability and performance: MindTabs achieved real-time cross-device synchronization with a Supabase backend and improved extension memory efficiency by 40%, while maintaining a 99.9% sync success rate. I also built a <200ms Flask-based WebRTC interview simulator (with RBAC via SQLAlchemy) and developed a production-grade RL trading agent using OpenEnv architecture, including a 60% trading-frequency improvement and an analytics dashboard using Gradio/Plotly deployed on Hugging Face. I’m certified in Generative AI, RAG, and Agentic AI (DeepLearning.AI) and AI Agents with ADK (Google Cloud).
