About

I build full-stack product systems where frontend execution, backend architecture, and delivery reliability matter.

My background spans product development at TokenFlow and direct delivery for private clients across finance-oriented and digital asset-related environments. I have shipped and supported product systems involving dashboards, structured workflow software, booking flows, payments, subscriptions, and backend-connected user experiences.

Known for ownership-driven execution, product thinking, and delivering structured software systems where usability, implementation quality, and operational reliability matter.

Experience

TokenFlow — Full-Stack Engineer

February 2025 – Present

At TokenFlow, I develop and improve client-facing product applications with a focus on reliable, maintainable, backend-connected web experiences. My work spans React, TypeScript, Node.js, REST APIs, dashboard interfaces, authenticated user flows, responsive layouts, and production-focused UI behavior.

I contribute across the full implementation cycle: defining product and client requirements, structuring technical tasks, implementing frontend flows, connecting UI behavior to backend logic, validating user journeys, debugging issues, and preparing features for delivery. The work is fast-moving and ownership-driven, with an emphasis on clean execution, maintainability, and practical product value.

Private Clients — Freelance Full-Stack Engineer

December 2023 – February 2025

Before TokenFlow, I delivered custom full-stack applications for private clients in finance-oriented and digital asset-related environments. These projects often involved reengineering manual spreadsheet workflows into structured internal tools with dashboards, data views, authentication flows, protected pages, CRUD-style management, payment-related flows, and responsive interfaces.

I handled projects from requirements to launch: planning features, designing the user experience, building the UI, implementing backend and API logic, testing real user flows, improving usability, and polishing the final product. This period strengthened my ability to take ownership, move independently, and deliver software that is practical, usable, and ready to present.
