I am a final-year Computer Engineering student (B.Tech, 2023 to 2027) at Shah & Anchor Kutchhi Engineering College, University of Mumbai. I build backend services, data pipelines, and applied ML systems, and I care most about robustness: retries, caching, schema validation, and guardrails against bad input and model hallucination.
I am currently a Backend Developer Intern at BillTea, working on a NestJS and Prisma backend that serves a React Native (Expo) app.
Looking for: SDE, backend, data, and applied AI/ML roles, both internships and entry-level, in Mumbai (on-site or hybrid) or remote.
Highlights
- Ranked 445 of 1,349 teams at HackerRank Orchestrate 2026 (12,885+ registrants across 48 countries) with a RAG-based support triage agent.
- Built Trustos, a browser extension that detects phishing locally using WebAssembly and a Bloom filter, and Sentinel Verify, a Flask platform with explainable ML threat detection.
- Five roles across backend development, web scraping pipelines, IT infrastructure, and web development.
| Area | Tools |
|---|---|
| Languages | Python, JavaScript (ES6+), SQL, Bash, WebAssembly, HTML5, CSS3 |
| Backend | NestJS, Prisma, Node.js, Express.js, Flask, SQLAlchemy, REST APIs, JWT auth |
| Frontend and mobile | React, React Native (Expo), Chrome Extensions (Manifest V3), Shadow DOM |
| Data engineering | Pandas, NumPy, Selenium, BeautifulSoup, ETL, data cleaning and validation |
| AI and ML | Scikit-learn, spaCy, PyTorch, RAG, LLM agents, explainable AI (XAI) |
| Security and systems | Bloom filters, zero-trust design, SIEM tools, TCP/IP, DNS, Linux |
| Tools | Git, GitHub, Postman, VS Code, Advanced Excel |
Zero-trust phishing detection extension for Chrome and Edge (Manifest V3).
- Checks URLs locally in the browser, so URLs and browsing history are never sent to an external server.
- Combines heuristic risk scoring, a WebAssembly compute module, and a local Bloom filter for fast URL lookups with no network round trip.
- Explains each warning in an isolated Shadow DOM overlay (spoofed login inputs, high-entropy domains) instead of silently blocking the page.
JavaScript WebAssembly Manifest V3 Bloom filter Shadow DOM
AI-powered threat detection platform for phishing, fraud, and deceptive content.
- Classifies content in real time with an ensemble ML and NLP pipeline.
- Returns explainable results that show why content was flagged, with confidence scores.
- Includes role-based authentication, a rate-limited API, scan history, and an analytics dashboard for attack trends.
