For 13+ years, global brands and funded startups have trusted me with the systems they can't afford to get wrong — and kept coming back.
Florianópolis, Brazil · working across US & EU time zones
I'm Alexey, and this is my independent engineering practice. Some of the world's largest entertainment, sportswear, and health brands have trusted it with their products — and so have startups betting everything on one system.
I work two ways: embedded in a client's team, moving at their standards, or leading a project outright — architecture, decisions, delivery — from first conversation to production. Either way, the common thread isn't a framework. It's trust with consequences: platforms serving global audiences, financial and legal records that must survive migrations, live phone systems that can't misroute a customer, launches with a date attached.
Much of this work is under NDA.
Away from the keyboard: I spent years traveling with my family following waves, and settled where they're best — Florianópolis, Brazil. I've written about how surfing and engineering train the same muscles.
Recent work.
Confidential enterprise media client — internal creative tooling
Led frontend development on an internal tool used to create and adapt visual materials across multiple formats. Built complex interactive editing workflows, precision UI behavior, and performance-sensitive frontend systems for production use.
Confidential enterprise media client — public web platform
Core engineer on a multi-locale public web platform with staged publishing, CMS integration, and reliable lead-capture infrastructure. Focused on frontend architecture, localization, content operations, and production reliability.
Confidential enterprise client — AI product experience
Frontend engineer on a high-traffic consumer experience involving AI-assisted creation and discovery. Built core UI flows, performance-sensitive gallery interactions, and reusable frontend systems in a cross-functional team.
Newfound / HomeLister — real-estate platform architecture
Principal technical architect across systems supporting listings, user workflows, MLS-driven rules, payments, e-signature, and live call routing. Led architecture and delivery across migration, modernization, and production-critical platform work.
Consumer health & hardware — Superpower, ChargeBot
I built a previous iteration of superpower.com — a 3D-heavy, animation-rich marketing site for a health platform — and the mobile app for ChargeBot, connected charging hardware that landscaping fleets monitor from their pocket. Different ends of the product spectrum; the same standard of finish.
Alongside these: AI/RAG systems built from scratch, payments modernization for a high-volume US retailer, and early-stage products I'd rather tell you about than list.
Inside enterprise teams I work in your stack, your process, your standards — no friction, no ego. Given a whole project, I take it to completion: architecture, delivery, the team it needs, and the decisions in between.
I've migrated legal and financial records, refactored live phone routing, and shipped launches with immovable dates. My default habits — reversible changes, shadow runs, honest status reports — come from domains where mistakes cost real money.
Most of my client relationships span years. The systems I build, I'm still operating — which changes how you build them in the first place.
