A portfolio that is itself a live, full-stack serverless system.

This site. Instead of claiming I can build systems, the site IS one: real-time chat to my phone, an AI that answers questions about me, and live telemetry — all on serverless AWS.

↳ A live system serving real visitors — not a mockup.

Paste a job description; a multi-agent pipeline tailors your resume into an ATS-friendly one-page PDF — live.

An AI resume-tailoring tool: paste a job description and a multi-agent LLM pipeline selects your most relevant experience, rewrites it into ATS-friendly bullets, compiles a one-page LaTeX PDF previewed live in the browser, writes a matching cover letter, and scores ATS keyword coverage.

↳ Live on the web — paste a job description and get a tailored, ATS-friendly one-page resume + cover letter, generated in a single streamed pass.

A layered Go + Gin backend for game management: players, rooms, challenges, payments, and logs.

A RESTful game management API built in Go (Gin + GORM + PostgreSQL) covering player management, room reservations, endless challenges, payment processing, and game-log collection. Ships with Docker Compose deployment, a clean layered architecture, and Postman test collections across five modules.

Full-link browser automation that hunts for French Schengen visa slots and auto-books them.

A Tampermonkey userscript that automates the entire French Schengen visa appointment flow on the TLScontact portal — from login through calendar selection — with auto-booking, Telegram alerts, and a sleep-resistant background monitor.

↳ Supports 7x24 'Background Insomnia Mode' with ~1-second precision monitoring

A Python medical Q&A chatbot exploring and comparing multiple ML and NLP modeling approaches.

A Python-based medical question-answering chatbot designed to understand user health concerns and return professional, accurate responses. The project trains and compares a range of machine learning and deep learning models on a medical Q&A dataset to evaluate which approaches best support a healthcare assistant.

↳ The study concludes that chatbot development can effectively understand user needs and provide professional, accurate, and detailed responses, supporting the use of healthcare QA chatbots in medical environments.

A hybrid rule-engine + LLM that auto-classifies and routes a Zoho inbox.

An AI email assistant for Zoho Mail that classifies, routes, and organizes mail with a hybrid rule-engine + LLM pipeline — a deterministic rule engine resolves obvious cases instantly and only ambiguous mail reaches the LLM.

↳ Cuts LLM API cost ~60–70% by resolving obvious cases with the rule engine before involving the LLM.

End-to-end test automation across browser UI, REST API, and manual test cases.

A software QA automation assessment that combines Playwright-driven UI tests against BBC Sport, Python API tests against a live exchange-rate service, and a set of documented manual test cases. Demonstrates a layered testing approach spanning automated and manual coverage.

Automatically hunts for earlier US visa appointment slots.
