⭐ 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.

I build and stabilize AI automation, agents, and full stack SaaS products that need to work reliably in production, not just in demos. I’ve shipped and scaled systems for founders from Y Combinator, Founders Factory, FutureLabs, and Republic of Work. Founders I’ve built with have gone on to raise €2M+, and my AWS/serverless work ranks in the top 0.2% for DevOps. A few results: ⚡ Multi-tenant SaaS with 28% faster integrations ⚡ Serverless system running under 200ms latency at 10K+ users ⚡ AI RAG system improving support efficiency by 45% ⚡ Next.js migration reducing hosting costs by 15% ⚡ SaaS MVPs shipped to production, with founders raising after launch A lot of products today get built quickly with Cursor, Lovable, Bolt, Claude Code, or an early freelance team. Then real users arrive. That’s when the problems show up: messy code, fragile backends, AI features that worked in the demo but fail in production, scaling bottlenecks, unreliable automations, and rising AWS costs. I help turn that into a production-ready system with clean architecture, a solid backend, reliable AI behavior, and room to scale. I also build new products properly from idea to MVP to production. What I can help with: * AI agents, chatbots, and AI voice agents * Workflow automation and business process automation using n8n, Make, Zapier, and APIs * Production RAG, LLM, and knowledge-based systems * Full-stack SaaS development with Next.js, React, Node.js, TypeScript, JavaScript, and Python * Backend systems, REST APIs, third-party integrations, and multi-tenant architecture * PostgreSQL, Supabase, Stripe, AWS, serverless, performance, and cost optimization * Stabilizing fragile or AI-built MVPs before they become technical debt How I work: We can start small. Send me your app URL, repo, or brief with a short note on the problem. I’ll review the likely bottlenecks, scaling risks, reliability issues, and what I would fix first before you commit to anything bigger. From there, I can take technical ownership of the build: architecture, backend, integrations, AI systems, delivery, and the parts that usually stall. I work best with: * Funded startups starting with or moving beyond MVP * SaaS teams hitting scaling, reliability, or cost issues * Founders who want a senior engineer to take ownership, not just ship tickets I’m probably not the right fit if you’re looking for the cheapest possible build. I’m a fit when the product matters, users depend on it, and it has to work. Tech I work with often: Python, JavaScript, TypeScript, React, Next.js, Node.js, AWS, Supabase, PostgreSQL, Stripe, serverless, OpenAI, Claude, Gemini, RAG, LangChain, AI agents, n8n, Make, Zapier, automation, and APIs. If your product was built fast and now needs to work properly, or you want it built right from the start, send me the repo, app, or brief, and I’ll tell you what I’d fix first.
