Led end-to-end modernization of the internal styling and order automation platform—from UX and design system definition to infra redesign—improving stylist throughput and reducing manual overhead. Translated customer preference signals into automated outfit generation workflows, including call workflows, styling, variant generation, order dispatch, and returns management. Introduced AI-driven recommendations leveraging past orders/likes to increase relevance and conversion quality. Architected a multi-tool ecosystem with a micro-frontend strategy using Nx (Next.js) + FastAPI to enable independent release velocity and domain separation. Established component libraries and a design system using React + Tailwind aligned to Figma, improving UI consistency and reducing feature delivery time. Implemented comprehensive testing (unit, integration, Playwright) and CI/CD pipelines via GitHub Actions, and added observability (CloudWatch, Instana) to surface bottlenecks and shorten MTTR. Colla
Owned end-to-end delivery of major features including User Onboarding, KYC flows, chart integrations, real-time stock price streaming, and the backend APIs powering them. Implemented shared Redux state models and business logic to enable parity across web and mobile apps. Built the internal design system, reusable component library, and private package repo used across product surfaces. Drove automation maturity with unit tests and E2E test suites, improving release confidence and reducing manual QA. Collaborated with design and product partners to translate user journeys into usable experiences and triaged production issues to improve user experience.
Led UI redesign during a platform transition from legacy PHP (Zend) to modern React + Go, ensuring a responsive, pixel-perfect interface aligned to the design system. Translated product requirements and customer feedback into UI/UX improvements and iterations. Contributed to Go microservice architecture by implementing new APIs and service components. Enforced strict test coverage (unit + integration), reducing regressions and increasing release confidence. Helped move the product from a monolithic architecture to a modular frontend and distributed backend. Acted as UI owner and decision driver in design discussions, ensuring feasibility, usability, and fidelity to strategic direction.
