Services

How I can help.

Useful software work starts with the real workflow, not a generic technical recipe.

01

AI and MCP integrations

I design practical AI and MCP integrations around real product needs, clear boundaries, and responsible handling of user data.

02

Application modernization

I help teams understand legacy constraints, improve the architecture step by step, and deliver a more reliable experience without treating a rewrite as the only answer.

03

Custom business applications

From discovery and architecture to delivery, I build focused business applications that are maintainable, secure, and useful to the people who rely on them.

Leadership and architecture

Leadership with technical depth.

I lead by making the work easier to understand and easier to improve: clarifying product intent, creating shared technical context, supporting good frontend decisions, and keeping quality connected to the people who use and maintain the product.

Experience

Close to the product, from direction to delivery.

A career across product teams, full-stack delivery, reusable Vue interfaces and frontend leadership.
