About

Senior Backend Developer | Node.js | NestJS | API Development

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.

Work Terms

I prefer clear communication and well-defined project requirements before starting any work. Once the project scope is confirmed, I can begin development immediately.

Payment terms depend on the size of the project. For small tasks, payment can be made upon completion. For larger projects, I usually work with milestone-based payments to ensure transparency and progress tracking.

I provide regular updates during development and make sure the client is informed about the project status. My goal is to deliver clean, reliable, and well-documented work on time.

Communication can be done through the Guru platform, email, or other agreed channels. I am flexible with time zones and committed to maintaining professional collaboration throughout the project.
