Full Stack Developer with 10 years of experience and Team Lead - your trusted long-term development and solution architecture partner The code is invisible; the outcome is not WIth me: - Autobound grew from one engineer to a 10-person team through 5+ years of our cooperation, and raised more than $4M in funding along the way. - DriverHRIS evolved from a slow 1000-screen system into a fully rebuilt product, backed by a 12-person dev team, over 4+ years. - Augmento expanded from a prototype to an 8-person dev team in 2 years, powering AR experiences for global brands and securing $2.5M in investment. At Wawibox (Germany, dental-industry SaaS), I've led the engineering team for 6+ years — owning the full rewrite of the legacy Vue 2 platform into a modern Vue 3 / Nuxt 3 / Node.js / TypeScript / PostgreSQL stack without a single day of downtime for paying clinics I'm also an early and heavy Claude power-user — AI-assisted development is part of how I ship, not a novelty bolted on. Cursor, Claude Code, agentic workflows, LLM integrations in production — I've been living in this stack since the day it existed. Got a product to build, scale, or rescue? Whether it's a new build, a team extension, or a legacy system that's slowing you down — message me and let's find a solution that actually fits your situation. The first 30 minutes are on me, and you'll walk away with a clear next step either way. 🚀 SEO Section What I do as a Full Stack Developer - and how to find me: I take on full stack developer SaaS builds, full stack developer fintech , Stripe usually , full stack developer ecommerce and full stack developer healthcare projects. I scope full stack developer marketplace platforms, full stack developer CRM integrations, full stack developer LLM features for AI layers OpenAI ChatGPT Claude Code, and full stack developer AI prototypes I've shipped as a web developer, a React developer, a WordPress developer, and a mobile app developer. Products rarely fit one box, so a web developer who's also a React developer, a WordPress developer, and a mobile app developer shipping React Native, iOS, Android Swift, and Flutter builds just moves faster and argues less. Stack I'm fluent in: JavaScript, Node.js, React, Python, Vue.js, API Integration, CSS3, CSS 3, HTML5, Laravel, MySQL, WordPress, Web Application, Web Design, Full-Stack Development, Software Development, Git, Tailwind CSS, Bootstrap, jQuery, Front-End Development Frameworks, Back-End Development Frameworks, Angular, and whatever Front-End Development Framework the team has standardized on. On the server, Node.js and Express for most new work, PHP with Laravel — full stack developer Laravel projects are common for me — and CodeIgniter for careful legacy migrations. Back-End Development Framework choices are tools, not religion. Python full stack developer engagements are some of my favorites: Python full stack developer Flask for lightweight services, Python full stack developer Django when a team wants batteries included. I also take on .NET full stack developer migrations when clients modernize off older stacks. Data and infrastructure: SQL, MySQL, PostgreSQL, MongoDB, Database Architecture thinking from day one, Firebase and Supabase for fast product iteration, AWS for production, REST and GraphQL API design, API Integration across third-party services. I work deeply in WordPress and Shopify — full stack developer Shopify builds ranging from theme work to full custom, plus full stack developer Webflow engagements, full stack developer Supabase projects, and full stack developer Twilio integrations. Web Design details get the same attention as the code. Adobe Photoshop when brand polish matters. JavaScript stays the connective tissue. I ship Web Application, Desktop Application, and Standalone Application as full stack web developer Software Design, Software Architecture & Design written down before the first line of code so Full-Stack Development stays coherent. Software Testing, Software Debugging before ship. Application Improvement and Software Consultation on live products. Agile Software Development with daily Git commits. Software Development I`m the most suitable developer for this role Every Full Stack Developer engagement I take on starts with review, whether you need a web developer, a React developer, a WordPress developer, or a mobile app developer I work as a full stack developer shopify and c# full stack developer .NET backend developer and web developer. Also as a mobile app developer and wordpress developer fullstack I am full stack developer react delivering as Full Stack Developer | React developer | Web developer fullstackdeveloper wordpressfullstack fullstackweb developer seniorfullstackdeveloper javascriptfullstack web developer full stack mobile app developer and web app developer node.js developer asp.net developer c# backend developer So all that makes me a Full-Stack Developer and Software developer + web developer
