I build web stuff. I build mobile stuff. Sometimes desktop too. I design the database. I build the frontend. The deployment pipeline too. Recent-ish things I’ve done: • made a frontend 5x faster because it was… not great • built dashboards that crunch a lot of data without freezing • wrote CMS tools so clients stop asking devs to change a button color • added payments so apps can finally justify their existence • cleaned up systems that grew “organically” (you know what that means) Stack is whatever gets the job done. Usually JS, PHP, some Python, occasionally Rust when I feel brave. React/Laravel a lot. APIs everywhere. Queues when needed. I’ve worked solo, in small teams, and once in a codebase where nobody knew who wrote what (character building experience). Important part • things I build tend to keep working. • clients don’t come back with “small issue bro” messages every week. You’ll probably want me if • your app is slow but “shouldn’t be” • you have data but no clue what to do with it • your last dev vanished • or you just want it done properly once No big promises. I just do the work and it holds up. Here is a few words my pas clients used to describe the experience of working with me • committed to Quality • collaborative • clear Communicator • reliable • solution Oriented • accountable for Outcomes • detail Oriented • professional if you want someone who can step into a half-broken system, figure it out, and not make it worse… feel free to reach out.

They are fully custom iGaming platforms with real-time game integrations, seamless wallet APIs, payment processing, and custom mobile UIs — built by me, live, and used by real players today. With 8 years of full-stack development experience, here's what I bring to iGaming and beyond: ♠ iGaming & Casino Development Custom casino platforms, sports betting sites, poker games, and slot game development.

If something in the spec or design doesn't make sense, I bring it up before we start instead of building the wrong thing in silence.
