01 / ABOUT

Engineer who ships systems, not just screens.

I'm a CSE student building end-to-end — type-safe APIs, retrieval pipelines, and the cursor pixels in between. My current obsession is the messy seam between deterministic systems and probabilistic models: agents, RAG, and ML experiments that actually generalize past the toy dataset.

Three years of self-directed building alongside coursework. LeetCode rating north of 1900, 20+ ML/DL models trained on real data, and a stack of full-stack side projects I keep iterating on. Aiming at SDE and ML roles for 2026.

03 / SELECTED WORK

Things I've shipped, not just sketched.

A few systems I've designed and built end-to-end. Hover for a preview, click to inspect.

  • PRJ-01
    Scrybe[ inspect ]

    A self-building knowledge base and full-stack RAG pipeline that ingests URLs and documents to provide LLM-generated answers grounded in citations. Features a custom data pipeline with Playwright scraping, ChromaDB vector search, and an interactive 2-D PCA retrieval map to visualize the embedding space.

  • PRJ-02
    Swagger2Drawio[ inspect ]

    A Python-based CLI tool and library that automatically converts Swagger and OpenAPI specifications into visual Draw.io diagrams. Features a custom graph engine and layout strategies to instantly map complex API endpoints, data models, and architectural relationships.

    PythonOpenAPI/SwaggerDraw.io XML
  • PRJ-03
    TaskFlow[ inspect ]

    A full-stack asynchronous task scheduling and execution system featuring custom-engineered worker pools. It enables defining, scheduling, and monitoring concurrent processes with real-time state updates via WebSockets.
