What I'm looking for

I seek backend or platform roles emphasizing scalable systems, team leadership, and opportunities to work with geospatial, real-time, and data-intensive architectures in a collaborative, growth-oriented company.

I am a backend engineer with five years of experience building reliable, high-performance web systems, mobile and desktop backends, and geospatial services. I have led teams and projects end-to-end, optimized databases and search clusters, and integrated payment, notification, and real-time systems to deliver production-ready solutions.

My work emphasizes scalability, observability and security: I’ve optimized PostgreSQL with PostGIS, built real-time ETL and search with ElasticSearch and Redis, scaled services on AWS with Docker and Redis, and integrated Stripe, Twilio, Auth0 and SendGrid. I enjoy mentoring engineers, solving complex backend challenges, and continuously learning—currently pursuing an MSc in Artificial Intelligence.
