Need a desktop app that feels native on Mac, Windows, and Linux? I'm an Electron developer who architects high-performance apps with deep OS integration, AI features, and FFmpeg-powered media processing. Most Electron developers stop at UI. I go deeper into system-level integration, resource-intensive media pipelines (FFmpeg, custom encoders), and AI-powered features like GPT-driven smart tools, giving your desktop app capabilities competitors can't easily replicate. I pair this with strong TypeScript/React front-end skills and Node.js backend work, so I can own a project end-to-end. Here's what I typically deliver: - Cross-platform Electron desktop apps (Mac, Windows, Linux) with native OS integrations - Media-heavy tools: screen recorders, custom video players, FFmpeg encoding pipelines - AI-powered features layered into desktop or web apps (GPT integrations, smart automation) - Chrome extensions and Next.js/React web platforms with TypeScript reliability - Cross-platform mobile apps in React Native, Flutter, or Ionic when a project needs it I act as a technical partner, not just a coder, helping translate business goals into an architecture that scales. Top Rated Plus on Upwork with over 20,000 hours logged and $495k+ earned across 20 completed jobs. Recent work includes an AI-powered screen recorder with GPT-driven smart features and a custom FFmpeg-based media player for a learning platform. If you have a desktop, media, or AI integration challenge, send me a message with a bit about your project, and I'll reply with next steps within a day.

I partner with founders, CTOs, and product teams that need a senior engineer who can take ownership of the technical direction, question risky assumptions, and move software into production without constant oversight. Over the past 10+ years, I have helped startups, SMBs, and established companies build SaaS platforms, AI-powered products, cross-platform desktop apps, and internal systems. Whether you are starting with an idea, scaling an existing product, or dealing with a codebase that has become difficult to maintain, I can take ownership of the engineering work needed to move it forward. You will get clear communication, fast responses, realistic estimates, and early visibility into technical risks. I do not wait until the deadline to raise concerns. I keep projects moving, explain trade-offs directly, and follow through on what I commit to. 🤝 How I Work I combine deep engineering experience with a modern AI-assisted development workflow. Tools such as Claude Code and Codex help accelerate implementation, refactoring, testing, and review tasks, while architecture, product decisions, security, and final validation remain guided by engineering judgement. ✅ Clear expectations from the start We define scope, priorities, constraints, and success criteria before development begins. ✅ Visible progress You receive consistent updates, direct answers, and early warnings when decisions could affect scope, cost, or delivery. ✅ Independent ownership I can work from a product idea, technical specification, existing repository, or partially completed prototype without needing constant direction. ✅ Quality at speed Automation helps reduce repetitive work, but every meaningful change is reviewed, tested, and validated before release. 🚀 What I Build I design, build, and improve production software across web, desktop, backend, AI, and cloud infrastructure. My work includes: • SaaS platforms, subscription products, and startup MVPs • React and Next.js web applications • B2B applications, dashboards, admin panels, and internal tools • Electron and Tauri desktop applications for Windows, macOS, and Linux • Chrome Extensions using Manifest V3 • AI-powered features, AI agents, RAG pipelines, document search, and LLM integrations • OpenAI, Claude, LangChain, embeddings, and vector search solutions • Node.js, NestJS, Python, and FastAPI backend development • GraphQL and REST APIs • CI/CD, cloud deployment, monitoring, and scaling I am most useful when a product needs to move from uncertainty to execution. That could mean turning an early concept into an MVP, rescuing a stalled prototype, improving a difficult codebase, adding AI capabilities to an existing product, or taking responsibility for the technical decisions that determine whether software performs reliably after launch. 🧩 End-to-End Product Ownership As a founding engineer, I can work across the complete delivery lifecycle: Product Planning → Architecture → Data Modelling → API Design → Backend Development → Frontend Development → Desktop or Extension Packaging → Testing → CI/CD → Deployment → Production Support I do not treat frontend, backend, infrastructure, and product decisions as isolated tasks. I look at how the complete system fits together and make decisions that support both current delivery and future growth. For desktop applications, I handle architecture, local storage, native integrations, packaging, installers, code signing, auto-updates, and release workflows. For AI products, I build practical solutions including AI assistants, automation workflows, document search, RAG systems, and LLM-powered features that solve real problems. ⭐ Experience • 10+ years building production software • 20+ products shipped • Top Rated Plus • 100% Job Success Score • Experience across SaaS, AI, fintech, healthtech, logistics, enterprise B2B, and desktop software ⚙️ Core Services • Full-Stack SaaS Development • React, Next.js, Node.js, NestJS, Python & FastAPI Development • Electron & Tauri Desktop Applications • AI Integration, AI Agents & Automation • API & Third-Party Integrations • PostgreSQL Architecture & Data Modelling • Architecture, Refactoring & Performance Improvement • Production Troubleshooting & Deployment Support 🛠️ Technology Stack React · Next.js · Angular · TypeScript · JavaScript · Node.js · NestJS · Python · FastAPI · PostgreSQL · GraphQL · REST APIs · Electron · Tauri · OpenAI · Claude · LangChain · AWS · Azure · Docker · Cloudflare · CI/CD 💡 Why Clients Bring Me In • I own architecture through production delivery • I work independently without disappearing into the codebase • I provide honest estimates and surface risks early I am a strong fit when you need a founding engineer or senior full-stack developer who can take responsibility for a SaaS platform, AI-enabled product, desktop application, or backend system from technical planning through launch.
