About

Senior Node.js & NestJS Developer | Microservices & API Architecture

I am a Senior Backend Developer and Co-Founder specializing in building scalable, enterprise-grade systems with Node.js and NestJS. With a career spanning from early-stage startups to co-founding MK codes, I bridge the gap between complex technical architecture and real-world business solutions.

My core expertise lies in designing Microservices and RESTful APIs that are not only functional but also high-performing and secure. Recently, I’ve focused on the manufacturing sector, developing smart workflow automation and industrial tools that help companies streamline operations and reduce errors.

What I bring to your project:

Architecture & Logic: Expert-level implementation of NestJS core logic, TypeORM, and SQL/NoSQL database design.

Security & Auth: Robust authentication systems using JWT, Passport.js, and secure third-party integrations (like SendGrid).

Scalability: Experience building multi-tenant SaaS structures and migrating monolithic applications to microservices.

Collaboration: A proactive, "team-first" communicator who excels in Agile (Scrum) environments and works seamlessly with frontend teams.

Whether you are a startup building an MVP from scratch or an enterprise optimizing a complex backend, I am committed to delivering high-quality code on time and within budget.
