I help growing businesses connect customer workflows, modernize existing platforms, and ship new products. Experience spanning startups to global enterprises, from the first decision through production.
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.
Away from the keyboard: I spent years traveling with my family searching for work-life balance and found it in Brazil. I've written about how surfing and engineering train the same muscles.
Selected work across business operations, enterprise software, and product experiences.
Confidential enterprise media client — internal creative tooling — via BlueInGreen
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 — via BlueInGreen
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 — via Dotdotdash
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.
Other work includes payments modernization, AI/RAG applications, and early-stage products. We can discuss the engineering approaches and the scope relevant to your business while respecting client confidentiality.
For a workflow or platform that is holding you back, we map the current system, identify the constraints, and agree on a practical next step. You get a prioritized plan with scope, risks, and an implementation estimate.
A customer portal, connected CRM and phone system, platform migration, or new product feature. We agree on what success means, then I lead implementation, testing, and a staged release with clear progress updates.
For teams that need continuing technical ownership, I can work alongside you on architecture, delivery, mentoring, and production support. We agree on capacity and priorities so you know what is covered.
