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 the back-of-the-napkin story.

04 / EDUCATION

Where the foundations got laid.

Formal schooling plus the self-directed track I'm running now.

EDU-01 · 2023 — 2027Uttar Pradesh, IN

Indian Institute of Information Technology, Sonepat

B.Tech · Computer Science & Engineering

Coursework spans DSA, OS, DBMS, computer networks, and machine learning. Final-year focus on applied ML and full-stack systems. CGPA: 8.5/10 (up to 6th semester).

05 / ACHIEVEMENTS

Receipts, in chronological order.

Things I'm proud of from the last few years — from competitive programming milestones to multiple projects.

ACH-01 · 2025

LeetCode Knight — 1900+ rating

Pushed past the 1900 contest rating mark on LeetCode after 700+ problems solved across DP, graphs, and segment trees.

ACH-02 · 2025

Hackathon — top 10 finish

Secured a top 10 finish in Inter-College Hackathon, building a AI-powered Resume Evaluator. Evaluated on innovation, technical complexity, and impact.

ACH-03 · 2025

ML/DL portfolio milestone

Trained and shipped 20+ ML/DL models across vision, NLP, and tabular data — from CNN classifiers to small fine-tuned transformers.

ACH-04 · 2026

Full-Stack Project Portfolio

Built and deployed multiple end-to-end applications using React, Django/FastAPI, authentication systems, databases, and cloud deployment workflows.

06 / CERTIFICATIONS

The paper trail.

Vendor certs I've earned to back the system architectures I sign off on.

Let's ship something good.

Open to SDE / ML roles for 2026, internships, and interesting side collabs.
