Selected Work

Five projects. Real outcomes.

P.01

CodeMas — AI Coding Assessment Platform

Masai School · First engineer reporting to CTO · 10K concurrent users · ~10K submissions/sec

Exam Generator — GPT drafts complete exams (questions + test cases) from topic and difficulty; human reviews before any persistence. ~80% faster exam creation.
Rubric Scoring Agent — async GPT grades every submission on correctness, code quality, approach, and edge cases (0–2 each) with per-dimension justifications. Consistent feedback at scale across 10K+ submissions — zero trainer overhead.
Socratic Hint Agent — for failed submissions, generates a pedagogical nudge pointing at the concept without revealing the answer. Students self-correct without trainer intervention.
Trainer Dashboard Agent — AI-generated cohort summaries and per-student performance narratives. Replaced manual spreadsheet reporting entirely.
Plagiarism Engine — behavioural signals (paste ratio, speed anomaly, tab switches) + TF-IDF cosine similarity. Reframed from "are submissions similar" to "did this student write this." Detection: 5% → 95% — a 19× lift.
Business Impact — automation eliminated manual exam oversight, making multi-cohort scale operationally viable. Each cohort = 400 students × ₹3L = $2M+ in revenue per cohort unlocked for Masai.

the01.dev — AI-Powered Ed-Tech Platform

Co-founder · Led engineering (2-person team) · Architecture owned end-to-end · 8 deep CS courses

PDF-to-Lesson Multi-Agent Pipeline — LangChain + Mastra with Planner-Executor and Supervisor-Worker patterns; human-in-the-loop approval via suspend/resume. ~67% reduction in unnecessary LLM calls via on-demand generation.
RAG Course Assistant — pgvector with HNSW indexing, hybrid cosine + BM25 retrieval, GPT-4.1-mini with source citations streamed via SSE; answers deep-link to the exact video timestamp. Zero hallucinations — grounded strictly in proprietary transcripts.
Adaptive Practice Engine — GPT-generated question banks, spaced repetition scheduling, and a concept knowledge graph in Postgres. Personalised revision paths with zero manual curation.
Payments & Access — Razorpay with atomic access provisioning + XOR-encoded video protection with Firebase App Check. Zero payment-access race conditions; proprietary content protected end-to-end.

Kalaam — India's First Hindi Programming Language

Open Source · TEDx Bangalore · npm · kalaam-core · 500+ monthly users

Multi-language Architecture — 5 languages (Hindi, Marathi, Bengali, Telugu, Odia) via centralized keyword configuration; adding a new language is one map entry, zero parser changes. Infinitely extensible without touching the interpreter core.
Fully Offline PWA — zero API calls, service-worker cached, runs in the browser on a budget Android phone with no internet. Reaches tier-3 city students locked out of every other coding tool.
Open-Source Community — led 10+ contributors through structured releases. 500+ monthly active users on kalaamlang.in.
TEDx Bangalore — invited to speak on "Why we should be able to code in our own languages." Recognised as a meaningful intervention in CS access for non-English speakers.
