About Me

I'm a software engineering student who builds robust backend systems and end-to-end products — from REST APIs and data pipelines to full-stack web apps. I care about writing clean, purposeful code and shipping things that actually work.

Right now I'm deepening my skills in system design and backend architecture while building projects that solve real problems. Open to internship opportunities in software engineering and backend development.


Tech Stack

Languages: C++ · JavaScript · TypeScript · SQL
Backend: Node.js · Express · PostgreSQL · Redis · SQL Server · JWT · REST APIs
AI & Tooling: Gemini API (Function Calling) · Transformers.js · N-API
Infrastructure: AWS · Docker · GitHub Actions · SSDT · Node-Cron
Frontend: Next.js · React · Tailwind CSS


Featured Projects

A custom-built HNSW vector search engine in C++ that builds a 10,000-vector (768d) multi-layer index in 221ms and reduces ANN search latency from a 4ms brute-force baseline to sub-millisecond. Bound into Node.js via N-API bindings with a Transformers.js NLP pipeline for text embedding generation.
Stack: C++ · Node.js · N-API · Transformers.js


SiloKrate — Logistics Orchestrator

Logistics and sales management platform with a normalized SQL Server schema enforcing ACID-compliant concurrent order processing, a read-only Gemini Flash AI agent via function calling for natural language inventory queries, and HttpOnly JWT auth with role-based access control across six modules.
Stack: Node.js · Express · SQL Server · Gemini API (Flash) · JWT · SSDT
🔗 Live Demo


SkillMatched — Job Recommendation Engine

Backend-focused job recommendation engine using cosine similarity scoring across 10,000+ simulated job vectors with 99.5% latency reduction via Redis caching (600ms → <3ms), automated weekly batch dispatch via Node-Cron across 1,000+ profiles, and a stateless JWT auth layer.
Stack: Node.js · PostgreSQL (Neon) · Redis · Next.js · Docker · GitHub Actions
🔗 Live Demo


Fine-tuned DistilBERT model for detecting cybersecurity-related content using NLP classification.
Stack: Python · Hugging Face Transformers


DocEase — Doctor Appointment Platform

Full-stack healthcare platform where doctors and patients can register, book appointments, and manage schedules.
Stack: Next.js · MongoDB · NextAuth · Cloudinary · Docker · Azure Pipelines
🔗 Live Demo
