I build software you depend on.
Lead Software Engineer · iOS & Flutter · SDK Development · AI Tools · Warsaw, Poland
Your app needs a senior iOS or Flutter engineer. You need someone who can read an existing codebase, ship production code on day one, and not need hand-holding. I've done this across healthcare, fintech, VOD, and banking — apps with millions of users.
You need someone to build or maintain an SDK. Most iOS developers have never built an SDK. I maintain one with 250+ GitHub stars that ships inside thousands of apps. I handle architecture, cross-platform strategy, testing, distribution, and community.
Your mobile team needs a tech lead. You have engineers but no one driving architecture, code quality, or cross-timezone coordination. I've led teams of up to 14 across Poland, the US, and India.
You want AI-assisted development that actually works. I built NOS — an open-source framework that turns Claude Code into a structured development team. I can help you integrate AI tooling into your engineering workflow without losing process discipline.
What people say
“A rare combination of deep engineering knowledge and strong leadership — he not only writes excellent code but also provides clear guidance that helps teams stay focused and productive.”
“Very skilled professional with high motivation to make software better with each single iteration!”
“A very strong senior developer, with great coding skills and with the ability to fully and deeply understand the code and the libraries and to create innovative smart solutions to tackle problems.”
“A talented developer with a proven track record of success, and his collaborative and team-oriented approach make him an asset to any organization.”
How I work
I operate as an independent contractor through a B2B arrangement (standard in Poland). I typically engage in three ways:
Team augmentation — I join your existing team as a senior or lead engineer. I read your codebase, follow your processes, and ship production code. Typical engagement: 3-12 months.
Technical leadership — I lead your mobile team. Architecture decisions, code review, sprint planning, cross-timezone coordination. Available as a fractional tech lead.
Focused projects — SDK development, architecture review, or mobile security audit. Defined scope, defined deliverable.
I work remotely from Warsaw, Poland (CET). I overlap comfortably with EU business hours and US East Coast mornings. I'm available for full-time or part-time engagements.
