Dragan Apostolski
Seven years of delivering production software across the stack: from high-traffic fintech at Bitstamp to building end-to-end products as a freelancer. Comfortable owning the entire stack: backend, frontend, infrastructure, and the AI layer on top. I am growing as a product engineer by scoping requirements, making architectural and UI/UX decisions, and iterating on user feedback.
Experience
Independently scoped, built, and deployed three production systems for clients in 2026: a voice AI lead qualification agent, a real-time voice receptionist, and a booking platform with payments and fiscal compliance. More details in Selected Projects below.
Technical lead for frontend and REST API work inside a smaller team at one of the world’s longest-running crypto exchanges (4M+ customers).
- Contributed to a secure, scalable pipeline for migrating 1M+ users from Bitstamp to Robinhood after the acquisition.
- Built Travel Rule end-to-end — UI, REST APIs, and the service behind them — the compliance step 100k+ customers pass when sending crypto, and a condition of the exchange’s operating licences.
- Owned the compliance back-office frontend and the REST APIs behind it, used by hundreds of compliance agents to request, review, and approve customer KYC and AML checks.
- Migrated the back-office frontend from Django templates to Nuxt, unifying frontend code and design tokens.
- Rewrote and fully migrated a legacy Ruby on Rails codebase to Django on the lead-generation platform primerjam.si / procompare.com, serving ~100k users across 4 countries.
- Built a system of Python web-scrapers triggered by cron jobs, aggregating data for 10k+ companies across 4 countries with rate-limiting, IP-rotation, and PostgreSQL storage.
- Developed backend services, REST APIs, and integrations on a Django back-office platform with a multi-tenant architecture (django-tenants).
- Implemented a new frontend from scratch (from Figma designs) using Django templates, JavaScript, HTML & CSS.
