About

I turn ambiguity into shipped product - at scale, with real users, and occasionally with the CEO in the room. Currently at HackerRank as an SDE Intern, where I'm working on AI copilot agents used by candidates in live assessments, building agent-powered tooling for assessment content creators, and collaborating with Staff Engineers on platform testing architecture and CI/CD. Also contributing to a new product line directly with the CEO. Before this, I co-founded Plan Sync - a campus scheduling app that grew to 7,000+ monthly active students, survived finals week, department expansions, and real-world chaos without crashing. Code that ships, scales, and gets used by actual humans (not just in demo day slides). I've also done backend engineering at Vettam AI (GCP, Docker, NGINX) and delivered 10+ full-stack projects as a Top-Rated Upwork freelancer. I thrive in messy, high-ownership environments - whether that's debugging prod at 2am or leading Flutter workshops with Google Developer Groups. What I bring: • AI/agent product development (LLMs, copilot systems) • Backend & cloud engineering (Django, Supabase, GCP, Firebase) • Platform engineering & DevOps (Docker, NGINX, CI/CD) • End-to-end ownership from 0→1 to 7K+ users Let's connect if you're building something hard. 📧 connect@delwinmathew.in 🌎 delwinmathew.in

Geographic Information System - Intern

Jun 2022 – Jun 2022 · 0 mo · Bhubaneswar, Odisha, India · On-site

Developed an Emergency App during the tenure of internship.
Motive: To provide immediate assistance / help in case of emergency by directly contacting local police station or hospital.
Why this works? This project severely reduces time lag that causes when one takes conventional way of contacting help, i.e. by calling 100.
It is decentralized, hence no to very minimal downtime.
Concept: Every PS / Hospital needs to register their local contact number, which will directly be shared with the person in distress. Nearby PCR vans are also notified in case of emergency.
Loopholes:
> Spam calls: temporary ban / revocation of service for user
