What I'm looking for

I'm looking to lead full-stack MVP delivery where I can own architecture, database design, cloud infrastructure, and technical decisions while using AI-agent workflows to accelerate reliable production outcomes.

I turn business ideas into deployed, monitored MVPs by owning architecture, database design, scope, security decisions, and delivery while orchestrating specialized AI coding agents.

At Visionap, I managed and developed multiple enterprise applications, led teams of up to six developers, introduced Agile practices, moved deployments to Azure DevOps, and supported client IT integrations.

I’ve repeatedly taken stalled products to MVP or production, including My Practice Guru at Call Axis and projects at Atitrade – GEA Capital. My work spans backend APIs, database design, CI/CD, cloud infrastructure, authentication, code review, and stakeholder collaboration.

I’ve built streaming applications with Angular, React Native, Roku SceneGraph, and BrightScript for Quickplay and Norigin Media, and delivered systems using NestJS, React, Angular, PHP, WordPress, AWS, Docker, and GitHub Actions. I also founded Tecgua, a multi-tenant cloud POS SaaS with modular subscriptions, billing, payments, WebSockets, and independent client databases.
