Hi, I'm Olga
Senior Frontend Developer · AI-Powered EngineerFrontend engineer with 8+ years architecting scalable apps across fintech, hospitality, healthcare, and e-commerce. TypeScript and reactive programming specialist, focused on reusable component systems and performance. Integrates AI-assisted development as a core part of the workflow.
Good frontends earn interest. The next engineer ships faster, not slower, on the code you left behind.
How I build
What I actually do on production work. Not poster quotes.
Architecture compounds
A JSON-driven form engine on the banking platform cut new-form delivery by ~50% and is still the team's default 18 months later. Architecture is the part of the codebase that earns interest. Every component contract, state boundary, and folder shape either pays down delivery cost or rents space.
Performance is a deliverable
10K+ row AG Grid dashboards with complex multi-level sorting, filtering, and aggregation. Proactively refactored the most complex platform module — decomposed it into focused services, separated data and UI logic with RxJS, zero regressions. Measure first, then cut. Bundle size, render path, and perceived speed are deliverables with numbers attached.
Tests are the refactor budget
80%+ unit coverage on owned modules. Critical journeys locked in Cypress. The tests are the refactor budget. They are how the team changes the system on a Friday and ships confidently on Monday, long after the people who first wrote the code have moved on.
AI as a teammate
GitHub Copilot, Claude, and Cursor in the loop for code generation, test scaffolding, and rapid prototyping. The engineer still owns the design, the review, and the ship decision. Cuts the boilerplate cycle significantly — with the same code-quality bar.
Lift the whole team
Senior shows up in the code review you didn't have to chase, the pattern the next hire picks up on day one, and the bug a teammate caught before it shipped. The most valuable thing a senior engineer does is multiply the people around them.
Experience
Five companies. Six domains: fintech, hospitality, healthcare, EdTech, crypto, B2B commerce. Frontends the next engineer can keep moving: a ~50% faster form pipeline on a digital banking platform, 35% navigation speedup on a learning SPA, 10K+ row virtualization on revenue dashboards.
