Oleksandr Gubsky
Engineering Lead & Product Founder. I build resilient systems for the modern web.
I am Oleksandr Gubskyy — a Senior Software Engineer and Product Founder based in the NYC Metropolitan area. My work focuses on the intersection of scalable infrastructure and product-led growth. From architecting core marketplace services at Upwork to building Kapitalist.finance from the ground up, I specialize in engineering systems that don't just work—they scale the business.
What I Build
Kapitalist.finance
Co-founder | Engineering & Product
Building a high-throughput financial insights platform from zero to market-ready architecture.
Upwork Marketplace
Senior Software Engineer
Architecting FE/BE services for one of the world's largest talent platforms, scaling marketplace infrastructure.
Project SEO/SEM Engine
Engineering Lead
Led the overhaul of performance-critical landing pages, scaling to millions of visitors with SEO-driven architecture.
Systems Thinking
My engineering philosophy and approach to building resilient systems.
Systems Thinking
"Engineering is about managing complexity, not eliminating it. I focus on creating systems with clear boundaries, predictable failure modes, and observable behavior—because in production, every system fails eventually."
Scalability as a Constraint
"I don't build for 'infinite' scale on day one. I build for evolvability—creating architectures that can be swapped or scaled without halting the business."
The Founder-Engineer Gap
"Coming from a Co-founder background, I treat code as a financial asset. If it doesn't serve a product goal or reduce long-term debt, it shouldn't exist."
"Damn, he is good."
Ready to build? I am available for select architectural consulting and high-impact contract roles.
