I’m Dragan Mitić, a senior software engineer, system architect, and founder with 15+ years of experience building scalable web applications, SaaS products, and complex backend systems. I help startups and growing companies turn ideas into production-ready products. Fast, clean, and built to scale. My core strength is backend architecture and system design, but what sets me apart is that I think like a product owner, not just a developer. I don’t just write code, I design systems that are reliable, maintainable, and aligned with business goals. Over the years, I’ve: Built and led development of large-scale platforms used across Europe Designed SaaS products from scratch (architecture → development → deployment) Worked on complex integrations and high-performance backend systems Helped teams simplify systems, reduce technical debt, and ship faster Tech-wise, I’m strongest with: Backend: Laravel, Node.js (NestJS) Frontend: React, Next.js Architecture: scalable systems, APIs, system design, DDD principles DevOps: Docker, cloud infrastructure, production deployments Recently, I’ve been focused on building my own SaaS product and working closely with companies that need a strong technical partner, not just someone to “code tasks”. If you’re looking for someone who can: - Take ownership of your product - Make solid architectural decisions - Deliver production-ready code (not prototypes) - Communicate clearly and think long-term then we’ll work well together.

I build scalable backend systems, data pipelines, and automation platforms used by SaaS, fintech, and e-commerce companies. With 14+ years of backend engineering experience, I specialize in designing high-performance APIs, distributed ETL pipelines, and large-scale automation infrastructure. $500K+ earned on Upwork across 270+ projects building backend systems and data platforms. Key strengths: • Backend architecture (Python, FastAPI, Node.js, .NET, PostgreSQL, Supabase, Celery/RabbitMQ/Redis) • Data pipelines & ETL systems • AI integrations and RAG pipelines on vector databases (pgvector, Pinecone, Qdrant) • Large-scale data extraction and reverse engineered APIs • Distributed workers and automation infrastructure I focus on performance, reliability, and long-term maintainability, delivering backend platforms that grow with the business and remain stable under heavy load.

I've spent the last decade building and scaling backend systems — mostly PHP/MySQL, but also Node.js, Go, and Python when the job calls for it. Most recently I spent 6 years as Lead Developer at Timewise — an appointment booking and POS platform for salons, gyms, studios, and other service businesses. I was responsible for backend architecture, API development, AWS infrastructure, and DevOps. I built and maintained the core systems that power scheduling, payments, staff management, and reporting. Outside of that, I've built everything from real-time trading systems with WebSocket feeds and live order execution, to full-stack SaaS apps, booking platforms, merchant dashboards, and analytics APIs. What I bring to the table: - Performance diagnosis and optimization — I work by collecting metrics across the request path, isolating the slow part, fixing it, and repeating until it's fast - Database expertise — query optimization, indexing strategies, connection management, schema design (MySQL primarily) - AWS infrastructure — EC2, RDS, load balancers, autoscaling, monitoring, cost management - DevOps — Docker, Kubernetes, CI/CD pipelines, automated deployments - API development — REST and GraphQL, built to handle load - Full-stack when needed — React, TypeScript, modern frontend tooling I communicate clearly and get to the point. I'm used to owning systems end-to-end — I don't need hand-holding to get things done. Tech: PHP, MySQL, Node.js, TypeScript, Go, Python, AWS, Docker, Kubernetes, Redis, GraphQL

I build frontend interfaces for SaaS products that actually ship to production. Not prototypes. Not templates. Real applications with authentication, role based access, payments, real time updates, and dashboards used by thousands of users. Over the past 10 years, I’ve contributed to 50+ software products across legal tech, healthcare, HR platforms, and inventory systems. I understand what production ready frontend looks like because I’ve delivered it many times. If you're building a serious SaaS product and need a developer who understands the full system, not just the UI, we’ll work well together.

Typical work includes: • Admin dashboards with advanced tables, filters, bulk actions, and exports • Multi step onboarding flows with validation and progress tracking • Role based systems with different user views • Real time features using WebSockets • Stripe payment and subscription interfaces • Notification systems including in app and email preferences • KPI dashboards and data visualization • Form heavy tools with complex business rules I don’t work on marketing websites or CMS themes.
