Hi there, I'm Subodh πŸ‘‹

I'm a Full-Stack & Web3 Engineer with a strong foundation in building scalable systems and shipping production software. I enjoy tackling complex engineering problems, whether it's optimizing latency in backend services, building async systems in Rust from scratch, or going on the ground to build vertical SaaS for local businesses.

πŸš€ What I'm Currently Working On

I'm the solo Founder & Engineer of KrushiSarthi, a cloud billing and shop-management SaaS built specifically for agricultural input shops in Maharashtra.

  • The Tech: Next.js, Node.js, PostgreSQL, Redis, LangChain, Docker.
  • The Impact: Built an offline-first PWA with multi-tenant architecture, AI-powered invoice OCR (LangChain), and government portal (SATHI) sync. Went on the ground to study real workflows and currently serve 50+ retailers.

πŸ› οΈ Core Engineering & Systems Focus

My technical expertise spans both modern web applications and low-level system design.

  • Languages: TypeScript, JavaScript, Rust, Python, SQL
  • Frontend & App: React, Next.js, React Native, Expo, Tailwind CSS
  • Backend & Data: Node.js, Express, PostgreSQL, Redis, MongoDB, GraphQL
  • Infra & DevOps: Docker, GitHub Actions, NGINX, AWS, Linux
  • Web3 (Solana/Rust): Anchor, PDAs, CPIs, Metaplex, SPL Tokens
  • Systems (Rust): Async I/O (Tokio), custom thread pools (work-stealing, graceful shutdown), QUIC / HTTP/3
  • AI/LLMs: LangChain, RAG pipelines, OpenAI / Gemini APIs, LLM Evaluation

🌟 Experience Highlights

  • Turbin3 Builder Cohort: Engineered production Anchor programs (AMM, escrow, vaults) on Solana with 100% test coverage. Explored validator networking and built an async HTTP/3 server from scratch in Rust.
  • Scale AI (YC) | AI Evaluator Intern: Evaluated code-generation LLMs across correctness, architecture, and maintainability. Reviewed 1,500+ TS/JS snippets and designed adversarial test cases for fine-tuning pipelines.
  • Matrix Soft Solutions | SWE Intern: Re-architected a high-throughput ERP backend in Node.js, cutting REST API latency by 40% via Redis caching and query optimization. Built Dockerized CI/CD pipelines to streamline releases.

πŸ“¬ Let's Connect

I'm always open to discussing engineering challenges, remote opportunities, and interesting ideas.
