Senior🎓
Top SchoolSaulius Vaičeliūnas is a Senior Software Engineer from Kaunas, Lithuania with 20+ years in software development and over a decade of professional experience building and leading engineering teams. He specializes in PHP/Symfony backends, modern frontend stacks (Vue/React + TypeScript), and cloud-native tooling (Docker, CI/CD, GCP/AWS), with a strong focus on maintainable architecture and pragmatic refactoring. As a tech lead and architect he emphasizes Clean Code, SOLID, TDD/BDD and creating systems that are easy to change without accumulating technical debt. He mentors engineers, drives platform improvements, and balances fast delivery with long-term quality—comfortable making short-term tradeoffs when necessary but disciplined about returning to robust designs. His background includes both hands-on implementation and shaping engineering practices across startups and established teams, and an early research internship in the US gave him a lasting appreciation for rigorous, testable solutions.
