Aleksandar Djordjevic

Senior Software Engineer

Full-stack product builder for platforms, internal tools, SaaS systems, integrations, automation, and support infrastructure.

About

I'm a senior full-stack product engineer with deep experience building production platforms, internal tools, SaaS systems, enterprise integrations, automation, and deployment workflows. I tend to work best where ownership matters: taking unclear product needs, shaping the technical path, and shipping reliable systems with minimal oversight.
Across freelance work, Zendesk systems, and the Upwork Community, I've delivered frontend, backend, data, support, and integration work across ecosystems like React, Next.js, Go, Node.js, PHP, Laravel, Shopify, WordPress, Flarum, Khoros, Zendesk, Okta, OpenAI, Webflow, Coda, CVent, and Vervoe.
The through-line is practical product delivery: custom apps, operational dashboards, LMS systems, export tooling, booking flows, payments, document workflows, community platforms, and the glue code that keeps teams moving.
When I'm not coding, you'll usually find me playing guitar, diving into Dota matches, tending to my garden, fishing, or watching movies from classics to sci-fi epics.
