PolandWhat I'm looking for
I'm a Senior Product Engineer with a frontend and design-engineering focus. I turn ambiguous product problems, whether they start as rough ideas, user feedback, or early designs, into polished software that ships.
Frontend is my deepest area. I architect and build complex React, TypeScript, and Next.js applications, with a strong focus on interaction quality, UX, performance, and maintainable frontend architecture. I'm comfortable making product and UX decisions directly in code and taking features from concept to production without needing every detail specified upfront.
I also work across the stack when the product needs it, including backend APIs, integrations, payments, data flows, and infrastructure. This lets me own an outcome end to end rather than stop at the frontend boundary.
I've built AI-powered product experiences, including voice agents, call-analysis tools, and AI-assisted workflows.
AI is also part of my day-to-day engineering process. I use coding agents and modern AI tools for prototyping, implementation, debugging, refactoring, and exploration, while owning the architecture, trade-offs, and quality of what ships.
Over the last 6+ years, I've worked with early-stage startups, product teams, enterprise customers, and major consumer brands. I've built products from scratch, owned frontend architecture, modernized existing platforms, and shipped experiences used at meaningful scale, with work contributing to improvements in revenue, engagement, performance, and delivery reliability.
The feedback I hear most often is that I combine strong engineering with product and design judgment, work independently, communicate clearly, and care about the final product rather than just completing the ticket.
I’m especially interested in teams where engineers have meaningful ownership over what gets built, not only how it gets implemented.
