lhs.dev is a one-person software studio run by Paweł Łukasiewicz, a senior software engineer based in Warsaw. I build full-stack web apps and the backends behind them, from first architecture sketch to production.
background
I started programming at 13 and have been shipping software professionally since 2018. Six years of freelancing on Next.js and Laravel apps, Discord bots and game-server tooling, including leading the dev team behind StrefaRP, a GTA V server network with a large concurrent player base. Since then: senior engineer on high-performance systems in a large enterprise, and founding engineer at deadend.ai, where I architected an AI SaaS platform on Next.js and Google Cloud.
I care about software that is typed end to end, easy to change a year later, and boring to operate. I work in Polish, Swedish and English.
