⭐ Top Rated Plus | 100% Job Success Hey! I'm Dubravko, a Solutions Architect with 7+ years of experience and the founder of Altitude IT, a co-located team of engineers in Serbia. We're not a faceless outsource shop. I'm hands-on in every project, managing my team and staying close to the work so nothing slips through the cracks. We also work alongside a partner design agency in our office, so we can cover the full product lifecycle from UI to infrastructure. We build systems that need to stay up when traffic spikes and complexity grows. A few examples of what that looks like in practice: -Built an API-driven platform that integrates with 20+ major airlines, automating rebookings, refunds and passenger data updates, used both as a standalone booking app and as a unified API that other businesses plug into their own systems. -Developed a real-time sports data aggregation platform handling live scores, schedules and news across soccer, basketball, baseball, NFL and Formula 1, restructured the data layer and optimized MongoDB to keep things fast under heavy load. -Created a FinTech commission management system that automated payment calculations, receipt matching, invoice generation and role-based access, cutting manual processing time and errors significantly for the client. -Shipped cross-platform mobile apps in e-commerce and education (React Native + Golang), including a grocery app with barcode scanning and payments, and a student discount app with QR codes and interactive maps. -Deployed Prometheus + Grafana monitoring on AWS EKS with Kubernetes and Helm for proactive infrastructure observability. Our stack: Backend: Golang, .NET, Node.js, Python | Frontend: React, Next.js, Angular, React Native | Infrastructure: AWS, DigitalOcean, Kubernetes | Databases: PostgreSQL, MongoDB, Redis, MySQL | Tooling: Prometheus, Grafana, Power BI How we work: We take on and prefer long-term engagements, multi-year relationships, not one-off handoffs. Communication is direct, clear and on time. I plan and architect every project before a line of code is written, and we iterate closely with clients throughout. If something breaks at 2am, we're the ones fixing it. Ready to talk? Send me a message and let's figure out if we're a good fit.
