Hyderabad, India — open to new opportunities
Syed Yaseenuddin builds the web end to end
Computer Science undergrad and full-stack developer. I design interfaces that feel considered and write APIs that stay boring under pressure — from JWT-secured Node services to AI-assisted React apps with real-time dashboards.
About
I like the parts of software most people skip — the edge case, the failing test, the extra half hour on something nobody will ever compliment.
Right now that means React and TypeScript for AgenticJobHunt's job-matching platform, plus the less glamorous half of the job — the 82 test cases I wrote that caught 5 bugs before release. On my own time I've built a concurrency-safe booking app, a subscription API with real auth and rate-limiting, and co-built a pregnancy-companion app with a four-person hackathon team.
An internship at IT Aspects taught me the rest — closing a Lighthouse audit's gaps one violation at a time until accessibility, performance and SEO all held up. None of it is flashy. That's kind of the point.

Experience
-
Full Stack Developer Intern · AgenticJobHunt
- Develop React and TypeScript features for agenticjobhunt.com, a job-matching platform with 300+ registered candidates that scores each job posting against a candidate’s resume using Claude and emails a daily shortlist.
- Wrote 82 functional test cases in Kiwi TCMS and found 5 bugs before release, including a database error that failed silently and an auth misconfiguration affecting two API endpoints.
-
Web Development Intern · IT Aspects
- Rebuilt a multi-section marketing website from a reference design in HTML, CSS and vanilla JavaScript, and fixed about 25 layout, mobile and interaction bugs.
- Raised Lighthouse scores for Accessibility from 70 to 100, SEO from 91 to 100 and Best Practices from 71 to 93 by correcting ARIA attributes, heading order and keyboard focus states.
-
Software Engineering Intern · Manac Infotech
- Built a Random Forest fraud classifier in scikit-learn on the Kaggle credit-card dataset (284K transactions, 0.17% fraud); tuning tree depth raised fraud precision from 22.6% to 93.9% at 72% recall (PR-AUC 0.64 to 0.83).
Selected work
SeatSync
An event-booking app where each booking is a conditional seat decrement inside a PostgreSQL transaction, so concurrent requests queue on the event’s row lock and an event cannot be oversold. Load-tested at 300 simultaneous bookings for 30 seats: exactly 30 succeeded and 270 were rejected with HTTP 409. Fixed a race where an admin changing an event’s seat count could erase concurrent bookings, using a compare-and-set update; 60 Jest and Supertest tests run in CI against a separate test database.
Subscription Tracker API
A REST API with JWT auth, Zod validation, rate limiting and NoSQL-injection filtering, Dockerized and deployed on Render with live Swagger docs and a database-aware health check. Upstash Workflow renewal reminders are safe to retry, skip past dates and stop once a subscription is cancelled or deleted. Fixed intermittent HTTP 500s on signup caused by how MongoDB transactions were committed; 49 Jest and Supertest tests plus lint, OpenAPI and format checks run in CI.
MomEase
Owned frontend and UI/UX on a four-person hackathon team building a pregnancy and postpartum app with 9 feature areas, including an AI chat, mood tracker, forum and shop, on shared shadcn/ui components. After the hackathon, ended production 500/503 errors in the AI features by moving to the supported Genkit Gemini plugin, cleared all TypeScript and ESLint errors, and added CI and a crisis helpline banner.
