I build scalable web apps, mobile apps, and AI-powered platforms for startups and businesses that need working software — not just code. Over the past 18 years, I've helped clients go from idea to MVP to production, and from clunky manual processes to automated systems that save real time and money. What I do best: Full-stack web development with React, Next.js, and Node.js (or PHP Laravel when that's the better fit) Mobile apps for iOS and Android using Flutter or React Native AI integrations — from OpenAI-powered features to custom automation workflows SaaS platforms built for scale, from database architecture to deployment API development and third-party integrations that just work Python automation and data scraping systems Admin dashboards and internal tools that make operations easier to manage Tech stack: React.js, Next.js, Node.js, Python, PHP Laravel, Firebase, Supabase, MongoDB, MySQL, PostgreSQL, AWS, REST APIs, OpenAI Why clients keep coming back: I treat every project like it's my own business — clear communication, honest timelines, and code that's built to be maintained, not just shipped. I've worked across SaaS, healthcare, real estate, booking platforms, and business automation, so I show up already understanding how to translate business goals into technical decisions. If you need a developer who can own a project end-to-end — architecture, build, and long-term support — let's talk about what you're building.

I build desktop apps from scratch and fix last-mile release problems that keep teams from shipping. Most clients come to me after days lost to Apple notarization, Windows code-signing, or cross-platform build failures. I diagnose it, fix it, and ship it, then leave documentation so your team can build independently. I also package desktop application plugins into easy-to-install desktop app extensions 60+ projects. 100% Job Success Score. Many clients return for 5+ continuous contracts. 𝐖𝐇𝐀𝐓 𝐈 𝐃𝐎: • Build full desktop apps from architecture to installable product • macOS code signing and notarization (Developer ID, Gatekeeper, stapling) • Branded Windows and macOS installers (WiX, Inno Setup, Advanced Installer, PKG, DMG) • Electron packaging, signing, and feature work (Electron Forge and electron-builder) • Legacy Java deployment rescue (Tomcat, Maven, Launch4J) Built with Java, JavaFX, Electron JS, and Spring Boot. Past work includes camera control software, audio workstations, AI assistants, DeFi GUIs, and file management systems. Most packaging projects ship in days, not weeks.

I’m a full-stack Java engineer who loves building fast, reliable backend systems and clean, intuitive frontends. Most of my work revolves around Spring Boot microservices, distributed systems, and high-performance APIs, but I’m equally comfortable crafting polished UIs when a project needs end-to-end ownership. I care about building software that feels smooth — where the backend is stable and secure, the data flows make sense, and the UI actually helps people get their work done. I’ve worked on financial and enterprise platforms where correctness, speed, and auditability matter, and it’s shaped the way I design and deliver systems. What I Bring to Your Project End-to-end ownership — I can design the architecture, implement the backend, and build the frontend that ties it all together. Strong backend expertise — especially with Spring Boot microservices, distributed systems, and performance-critical workflows. Experience in financial/enterprise systems — correctness, consistency, and reliability are non-negotiable. Clear communication & practical thinking — I translate business needs into clean architecture and production-ready code. Modernization skills — refactoring legacy codebases into scalable, event-driven, microservice-friendly systems when it actually adds business value.
