Full-stack Web Developer & AI Engineer.
Hi, I'm Aleksandar, a full-stack web developer and AI engineer near Munich, and I've been building for the web for 15 years. Whether I'm working at my day job at NiCE Cognigy or launching my own AI products, my focus is the complete B2B and B2C web stack.
AI brand-visibility SaaS. Mention rate, share of voice, and sentiment across ChatGPT, Claude, Gemini, and Perplexity, with the content brief that closes each gap.

How I work
AI is part of the job now.
I build full-stack AI products end to end: the front end, the back end, and the AI in between. Real ones, not demos: a multi-tenant SaaS, a local-first agent pipeline, a voice-notes app in closed beta, an npm package, and browser tools that are live today. Four of them you can open before we ever talk.
- Websites100+ shipped over a decade
- Live nowApsolut Cortex, Prompt Stash, SheetBuddy, PasteKit
- Closed betaVoice Notes, CIA
- In buildBrand Intelligence
- StackTypeScript, React, Next.js, Node
- Daily driverClaude Code, n8n, OpenRouter, Turso, Coolify
- StandardsCode review, accessibility, tests, docs
What I bring
What you get beyond a working website.
The website is the baseline, and the difference is everything I bring around it: AI wired into your product, the internal tools nobody has to ask twice for, and the automation that quietly handles the busywork.
Runs onAuth & multi-tenant data · Model routing, OpenRouter · Cost tracking, Helicone · Evals & tests · Durable storage
- A production-grade website, not a template
- AI built into your dashboards
- Small internal tools, shipped fast
- Desktop apps (Electron, Tauri)
- Automation with n8n
- Structured data that gets you cited by AI
- Prototype in days, hardened for production
I never once saw him hit a wall without already having a Plan B and a Plan C lined up. If a tool he needed was out of reach, he’d just build it. Cool under pressure, always prepared, and never without a solution.
How I help
Four ways I’d help your team.
AI built into your product
LLM and AI features wired into your product and dashboards, production-grade, not a demo notebook. It's the same shape as CIA, my agent pipeline you can inspect.
