Mykolas P.

Full-Stack developer with a CS research background, focused on building fast, reliable web apps and internal tools that actually ship. I’ve worked on everything from React frontends and REST APIs to GPU-accelerated research code, and I care a lot about clean architecture, performance, and reproducible builds. Some examples of what I’ve done: 1. Cut a manual trade-reconciliation workflow from ~3 hours to 45 minutes/day for 20+ analysts by building an internal securities-management platform (C#/.NET API + React + SQL Server). 2. Reduced complex report latency by ~45% through better schema design and indexing. 3. Built and shipped full-stack event-planning and portfolio sites (React, Node/Go/Python, PostgreSQL, Docker) with clean deployment pipelines and logging. 4. Designed and taught Python/OOP/DSA curriculum with a 90% certification pass rate (n=120), so I’m comfortable explaining technical systems clearly to non-technical stakeholders. Tech I’m comfortable owning end-to-end: - Frontend: React, Vite, TypeScript/JavaScript, Tailwind - Backend: Go, Python, Node.js, C#/.NET, REST APIs - Data & Infra: PostgreSQL, SQL Server, Redis, Docker, Nix/WSL2 Specialties: performance optimization, parallel/GPU work (MPI, CUDA), compilers, cryptography What you can expect working with me: - Clear scope and estimates before we start - Small, reviewable milestones instead of big, risky “mystery” drops - Thoughtful tradeoff discussions (speed vs. robustness, cost vs. complexity) - Proper documentation and handoff so you’re not locked to me forever If you need a developer who can take a fuzzy idea and turn it into a clean, testable, production-ready app or API, let’s talk. I’m especially good with: - MVPs and prototypes that still follow sane engineering practices - Internal tools/dashboards that save your team real time - Performance tuning and refactors of existing systems that feel “slow and fragile” Send me a short description of what you’re trying to build or fix, and I’ll reply with: - A quick assessment of how I’d approach it, and - The first 1–2 milestones I’d propose.
