About

With over a decade of experience in the IT industry, I specialize in backend development within the Node.js ecosystem. I’m primarily a Node.js developer and co-founder of InnovaCrew.io — a company focused on delivering applications, currently working on an AI-powered edtech platform. I’ve progressed from hands-on development to technical leadership roles, while maintaining strong coding practices.

I excel in designing and implementing high-performance, secure APIs using modern Node.js frameworks (NestJS, Fastify, Express.js) with both SQL (PostgreSQL) and NoSQL (MongoDB) databases. My expertise includes building robust authentication systems, optimizing database queries, and ensuring API scalability.

Additionally, as a shareholder at Sitebox.io, I contributed to backend API development and led the implementation of ISO 27001 and Cyber Essentials certifications. This experience has strengthened my focus on security-first development, including coordinating penetration testing and enforcing security policies.
