Founder and Full Stack Web Developer
May 2026 - Present • 2 mos
Founded and developed HeliosLab, a local-first AI operations platform built with Next.js, React, TypeScript, Tailwind CSS, Prisma, and SQLite. Designed and implemented responsive user interfaces, dashboards, workflow systems, API routes, background processes, file-management tools, and integrations with local and external AI engines. Built reusable front-end components, database-backed features, authentication and configuration flows, system monitoring, reporting, and project-management interfaces. Managed the full product lifecycle, including architecture, UI and UX design, development, testing, debugging, performance improvements, and product strategy. HeliosLab is currently in active development and demonstrates my ability to turn complex requirements into polished, maintainable web applications.

Developed and maintained the TShirt4U.gr B2B e-commerce website, supporting more than 1,900 active products. The platform includes product mockups, color selection tools, model photography, responsive product pages, and a video-driven landing page. I also built a second shop experience within the website, with its own landing page, navigation, menu structure, and product presentation. My work covered front-end development, responsive design, product organization, usability improvements, debugging, deployment, and ongoing maintenance.
