About Me
01I'm Mithlesh Kumar Das, a software developer from Biratnagar, Nepal. I build complete systems — full-stack products, backend services and AI/RAG workflows — and I'm currently completing a Bachelor of Information Technology at Mahendra Morang Adarsh Multiple Campus.
My recent work sits where business operations meet engineering: Stockpilot, an ASP.NET Core inventory system with an immutable stock ledger and weighted-average costing; Release Guardian, a synthetic monitoring and release-verification platform built with FastAPI, Next.js, Playwright and Lighthouse; and Water Factory ERP, a warehouse-scoped inventory, delivery and receivables system with RAG knowledge flows.
I care about the parts that keep a product correct after launch: data models, concurrency, role-based access, audit trails, tests, Docker, CI/CD and observability. I work in Git and GitHub as a first habit and ship production client websites on Vercel alongside the backend systems.
I'm open to full-stack, backend and AI engineering opportunities, as well as freelance work. If you're building something that needs reliable systems and a product-minded engineer, I'd love to hear about it.

My Projects
02Release Guardian — synthetic monitoring & release verification
A self-hosted, multi-tenant reliability platform that runs deterministic HTTP, real-browser and Lighthouse checks against production sites. It stores evidence, detects latency and regression changes, correlates failures with deployments, and manages incidents through to resolution. The control plane is FastAPI, the dashboard is Next.js, and Celery/Redis handle scheduling and browser workloads. Currently pre-1.0.
Stack: Python · FastAPI · Next.js · TypeScript · Playwright · Lighthouse · PostgreSQL · Redis · Celery · Docker
Stockpilot — inventory & stock control
An ASP.NET Core MVC inventory system for small and medium businesses. Purchases, sales, an immutable stock ledger, weighted-average valuation, concurrency-safe deductions, reversible transactions, role-based access, an append-only audit trail and CSV reports. Built on .NET 10, EF Core and PostgreSQL 17, with xUnit integration tests against a real database.

Stack: TypeScript · React · Vite · Express · Gemini AI · Web Audio API
StockMatrix — multi-market real-time stock terminal
A full-stack trading dashboard covering NASDAQ, NYSE, NSE, BSE, LSE, Euronext, Tokyo and HKEX. FastAPI issues OAuth2/JWT auth, caches Yahoo Finance data with TTL, and streams per-user WebSocket updates. The React + TypeScript frontend renders SVG candlestick charts, evaluates price alerts, supports multi-currency conversion, i18n and dark/light themes.
