All Case Studies

Twelve projects by Archit Jain, from distributed systems and GPU kernels to shipped web apps, each written up as an honest case study: what was built, the decisions behind it, what broke, and what’s next.

  RaftKV

  99% MatchSYSTEMS2026

  A replicated key-value store on a from-scratch Raft in Go: 1,000 randomized fault schedules and 180,000 operations with zero linearizability violations, a checker proven by injecting real consensus bugs, and the same code running live in your browser as WebAssembly.

  mini-vLLM

  97% MatchAI / ML2026

  A small vLLM: Qwen2 written from scratch in about 700 lines of PyTorch, a paged KV cache, continuous batching with preemption, and an OpenAI-compatible streaming server. Checked token-for-token against Hugging Face, and up to 1.55× Hugging Face's generate throughput on a T4.

  Triton FlashAttention

  95% MatchAI / ML2026

  FlashAttention-2 forward and backward in Triton, tuned for the free Kaggle T4: 1.55-1.92× faster forward and 1.64-1.83× faster forward+backward than PyTorch's memory-efficient SDPA, using under 60% of its peak extra memory. 79 of 79 tests pass on the GPU.

  AgentTrace

  93% MatchAI / ML2026

  Record, replay and diff LLM agent runs. A from-scratch Myers diff over agent steps finds the first step where two runs part ways, and replay pins tool responses so a run can be re-checked offline. Works with LangGraph and as an MCP proxy, at 8.6 µs of overhead per recorded step.

  ModelMux

  91% MatchAI / ML2026

  One OpenAI-compatible API in front of many LLM providers. Every model name is a fallback chain, so a rate-limited or dead provider is skipped before your client sees a byte. Adds about 0.14 ms at the median and recovered every recoverable request across five fault scenarios.

  Alankar Jewellers

  88% MatchFULL STACK2026

  A real client's storefront and back office: every piece is priced live from India's official IBJA gold rate, with an itemised breakup of metal, making charge, stones, hallmarking and 3% GST. Next.js 16 on Cloudflare Workers and D1, a secured staff admin, and 496 passing tests.

  Hardened MCP Servers

  88% MatchAI / ML2026

  Three read-only MCP servers (SQLite, filesystem, web fetch) that treat every tool argument as hostile: SSRF checks that survive DNS rebinding, read-only SQL enforced by SQLite itself, symlink-safe file access, ReDoS timeouts and gzip-bomb caps. 167 tests at 94% statement coverage.

  AI Resume Shortlisting Tool

  88% MatchAI / ML2024

  An explainable resume-to-job-description matcher: TF-IDF + cosine similarity produces a weighted match score, and a skill-gap analysis tells the candidate exactly which skills are missing — served via Flask web UI, a CLI, and a Python API over one shared engine.

  SmartBlog AI

  88% MatchFULL STACK2024

  A MERN app that generates GPT-4 blog drafts and scores them with a from-scratch SEO engine (readability, keyword density, structure) behind full JWT auth. Phase-1 MVP: backend complete, frontend covers auth + AI generation.

  Insurance Brokerage System

  88% MatchFULL STACK2024

  Next.js 15 + TypeScript insurance brokerage management system for the Nigerian market: clients, policies, broking slips, credit/debit notes, claims, and commissions, with a real brokerage/VAT/statutory-levy calculation engine over a ~44-table Drizzle/Turso schema.

  SmartBin WBC

  88% MatchAI / ML2023

  A dual-subsystem smart-bin project: a hardened Node/Express + SQLite QR-feedback dashboard, plus a Python OpenCV/TensorFlow ensemble that classifies waste as biodegradable vs non-biodegradable and drives an Arduino to sort it.
