I’m a full-stack developer with deep expertise in Angular and .NET, specializing in building seamless hybrid applications that bridge desktop and web. From crafting flicker-free UI with Angular route resolvers to architecting robust backend services in .NET Core, I deliver scalable, maintainable solutions with precision. 🔧 I thrive on solving complex activation flows, optimizing IPC mechanisms, and refining MSIX packaging for flawless deployment. Whether it's protocol activation, COM/DCOM interop, or registry cleanup—I've got it covered. 🚀 Let’s build something powerful, elegant, and ready for global scale.

Most backends look fine in a demo and fall apart the moment real traffic hits. I build the ones that hold up. Over the last 5+ years I've shipped production systems that process 100M+ records a month, power SaaS products thousands of people use daily, and keep running when load spikes instead of paging someone at 2am. If you're a startup or SaaS team, the problem usually isn't writing code. It's that the system got built fast to ship an MVP, and now it's slow, fragile, or hard to extend without something else breaking. The work I'm best at is taking a system from "it works for now" to "it scales and we trust it." TECH STACK & SKILLS Backend: Node.js, Express.js, NestJS, TypeScript APIs & Architecture: REST APIs, Microservices, Multi-Tenant SaaS Real-Time: WebSockets, SocketIO Databases: PostgreSQL, MSSQL, MongoDB, query optimization Queues & Background Jobs: Redis, BullMQ, event-driven processing Frontend / Full-Stack: React, Next.js DevOps & Cloud: Docker, Kubernetes, AWS WHAT I CAN HELP WITH - Building a new product or MVP from scratch - Designing scalable REST APIs and microservices - Real-time apps that stay in sync under load - Multi-tenant SaaS platforms - Database design and performance tuning - Queue systems, background workers, and reporting pipelines - Optimizing or rescuing an existing system that has outgrown its setup RECENT WORK - A real-time machine monitoring and analytics platform handling 100M+ records per month - Event-driven pipelines built with Redis, BullMQ, and WebSockets - Production SaaS applications serving thousands of active users - Reporting systems and background workers for enterprise clients running business-critical data I write maintainable, production-ready code with a clear paper trail, not quick fixes that become next quarter's emergency. I'm a strong fit if you want someone who owns the technical side and thinks a step ahead. Probably not your person for a one-off $20 script tweak. If this sounds like your situation, send me a short note about what you're building and where it's stuck. I'll tell you honestly whether I'm the right fit and how I'd approach it.
