I'm Anastasiia — I design and build software end to end, from backend architecture to the interface people actually use. Independent consultancy for teams who want a builder, not just a pair of hands.
Scoped around what the project actually needs — one feature, one product, or the whole technical side of a company.
Full-stack builds from first commit to production — web apps, internal tools, and customer-facing platforms, with product thinking baked in from day one.
Backend systems, APIs, and integrations designed to stay maintainable as the product grows.
Hands-on advisory for founders and teams — architecture reviews, stack decisions, and shipping unblockers.
Experience leading delivery as a team lead — useful when a project needs someone to own outcomes, not just write code.
"Hardworking and dedicated — five-plus years building full-stack software, owning products, and leading the teams that ship them."
Bilona is the independent practice of Anastasiia Bilonizhko, a full-stack developer and team lead based in the Netherlands. After years leading product and engineering inside teams, she now works directly with small businesses, startups, and independent teams who need a builder who understands both the code and the product around it.
