What I'm looking for

I am seeking senior backend roles where I can architect scalable API and cloud-native systems, lead technical teams, collaborate cross-functionally, and drive product and digital transformation.

I am a backend-focused software engineer with over 12 years building scalable web applications, APIs, and distributed systems using Node.js (NestJS), MongoDB, and cloud-native architectures.

At Needle Innovision (acquired by Veltris) I served as Principal Engineer / Technical Lead, designing high-volume backends, RESTful APIs, microservices, and integrating blockchain and AI/ML components while leading agile teams.

I also work part-time as a Technology Lead, architecting and deploying backend solutions (Node.js, Express, MongoDB, PHP, MySQL), managing technical strategy, client relationships, and delivering SEO-optimized web applications.

Earlier, I led teams building internal web and mobile applications, modernized legacy systems, and automated processes to reduce reporting time; I hold a BSc (Physics, Maths & Computer Science) and have published research on blockchain applications.
