🌐 Web Development Services
I build web applications that look sharp, feel snappy, and scale smoothly. Whether you are launching a brand new SaaS product, upgrading an internal tool, or need a performance injection for a lagging platform, I handle everything from pixel-perfect UI execution to robust backend systems.

Full-Stack SaaS & Web Apps: End-to-end engineering using React, Next.js, and Node.js or NestJS. I build secure user authentication flows, dynamic dashboards, and deep database structures using PostgreSQL or MongoDB.

Frontend Architecture & UI Engineering: Creating highly responsive, accessible web layouts from advanced Figma designs. I specialize in building reusable component libraries and fine-grained reactive state systems that stay fast as your application grows.

API Integration & Webhook Funnels: Connecting third-party services, building reliable REST APIs, and stabilizing complex data pipelines. I specialize in normalizing erratic external payloads so your production system runs with zero bugs.

Performance Optimization: Eradicating dependency bloat, speeding up server-side rendering, and streamlining asset delivery to ensure your web app loads instantly on any device.

💻 Desktop Development Services
When web browsers aren't enough, I build high-performance, autonomous desktop software that integrates deeply with local operating systems. I focus on creating lightweight runtime experiences that handle intensive local tasks without breaking a sweat.

Cross-Platform Apps with Electron & Bun: Building native-feeling desktop applications for Windows and Mac using web technologies. You get the speed of modern web development combined with full desktop capability.

Local Data & Hardware Integration: Making use of local system resources, file systems, offline storage, and low-latency WebSockets for real-time local communication.

Modular Runtime Environments: Engineering embeddable viewer libraries and modular tools, ensuring that heavy local rendering or complex data processing operates completely independently from your main server infrastructure.

Custom Tooling & Automation: Creating automated desktop tools, including custom Figma plugins that translate designs into clean data configurations, saving your team hours of repetitive manual development.
