Atishay Jain
Mechanical engineering undergrad at SGSITS Indore, writing software the whole way. ICPC regionalist. I build scalable systems from scratch and ship them: two government apps live on the Play Store, merged fixes in Bitcoin Lightning infrastructure, and a stack of client work across three years.
The numbers
ICPC 2025, Rank 12 at the Mysuru on-site regionals. Live cards, straight from each platform.
One year, every platform
GitHub commits, Codeforces submissions and LeetCode solves, summed into a single day.
Open source
Every PR and issue, pulled live from GitHub. Nothing hand-picked.
rust-lightning (LDK), Bitcoin Lightning infrastructure
since Jan 2026Summer of Bitcoin 2026 QualifierFuzzing and CI infrastructure. Cross-version serialization coverage using isolated multi-version dependencies to validate ChannelMonitor compatibility, and state-shifting encoding that lets concurrent channel monitors be reload-tested independently during mid-fuzz node restarts, which surfaced state asymmetries upstream.

Shipped
Government platforms, client products, institute systems. Filter by what you're looking for.
YES, Wellness Platform
State-wide wellness platform, launched by the Chief Minister of MP. I built the backend for ~5k concurrent users and killed a booking race condition with PostgreSQL row-level locking that was double-allocating slots under peak load. K6 stress testing to a sub-100ms P95.
SRAM
Labour-department platform, shipped to the Play Store.
4Moral
Production social and marketplace app. Six account types, real-time chat over sockets, orders using Mongo transactions, JWT auth, media pipeline, EC2. I also ran the pre-launch security pass, fixing NoSQL injection, IDOR and mass-assignment holes and taking dependency vulnerabilities from 21 to 9 without breaking the build.
dlab
Full-stack web and mobile build.
Livehood
Fixed core defects and optimised an existing production site.
Logistik
Logistics platform with real-time tracking over maps.
PF Management System
Provident-fund system for the institute finance department. ₹1Cr+ in monthly funds, automated reconciliation, bulk imports of 10K+ records, RBAC and persistent audit logging.
Products
Two Chrome extensions people installed without being asked to.
PRD Verification Tool
PDF compression, conversion and renaming with auto-filled Google Forms. 150 users.
LeetCode Analytics
CP-focused metrics injected directly into LeetCode profiles: difficulty spread, topic breakdown, trends, over their GraphQL API with no data collection. 130 users.
Hackathons
CIIS, Anti-money-laundering detection
Graph neural network finding anomalous transaction clusters across 1M+ records, with a SHAP explainability layer so an analyst can see why a case was flagged. Top 5 of 500+ teams (SBI, ClearTrail, MP Police), converted into an internship offer.

The ask section on this page runs two models in your browser and nothing leaves it. MiniLM embeds every chunk of my real content, cosine similarity picks the closest three, and a 77M-parameter Flan-T5 phrases the answer from only those chunks. No inference API, no key, no cost per question.
The first version failed on a question as basic as "have you worked in Java". The retrieval was fine; the corpus was the bug. I had indexed projects and experience but never the skills list, so the one chunk that could answer it did not exist. Worth remembering that a RAG system fails silently in exactly this shape: fluent, confident, and about a document you forgot to feed it.
It is deliberately a small model. A big one would be smoother and would also invent an internship I never did. The whole point of this site is that every claim is checkable, so the generator only gets to rephrase retrieved text.

About
I'm on a mechanical engineering degree and I've spent it writing software. That started as stubbornness and turned into the useful part. I don't have a lane I'm defending, so I go wherever the interesting problem is, Rust fuzzing infrastructure one month, a payments race condition the next.
What I actually care about is building scalable systems from scratch. That has meant government platforms on the Play Store, a provident-fund system moving over a crore a month, client backends in production, and two Chrome extensions people installed without being asked to.
For a while I contributed to open source the wide way, pull requests across a dozen projects at once. It taught me a lot and landed little. So I narrowed. Since January I've been in rust-lightning, on fuzzing and CI infrastructure, where the review bar is high and the code ships to people running Bitcoin nodes.
