Senior Full-Stack Engineer · Product & AI
I build software from idea to production, working across frontend, backend, architecture, and everything in between.
I like finding simple solutions to complex problems. Occasionally, the other way around.
Currently building open-source tools, SaaS products, and occasionally things nobody asked for.
Open to interesting opportunities and collaborations.
- 💻 5+ years of experience building production software.
- 🛠️ Full-stack development with TypeScript, React, Vue, Node.js, and PostgreSQL.
- 🚀 I enjoy taking ideas from concept to production.
- 🤖 AI is part of my daily development workflow.
- ⚡ I automate things to save time. How much time? Let's not get into that.
- 🐛 I write bugs. Occasionally, I fix them too.
Somewhere between frontend, backend, SaaS, and AI, I occasionally finish a project before starting another one.
Open-source observability for developers.
Because apparently, writing bugs wasn't enough — I also wanted to track them.
Telemetry Tracker is an open-source observability platform I've built from scratch.
It includes:
- Error tracking and monitoring
- Custom SDKs for JavaScript, React, Next.js, Node.js, and React Native
- Sessions, events, and performance monitoring
- Multi-tenant architecture with organizations and projects
- API keys, usage limits, and subscription billing
- Alerts, webhooks, and integrations
- Self-hosting with Docker
- CI/CD and production infrastructure
From architecture and development to deployment, documentation, and maintenance — it's a one-person operation.

AI-assisted publishing platform exploring automated content generation, SEO optimization, and publishing workflows.
I'm particularly interested in finding ways to make development faster, smarter, and less repetitive.
I use AI tools throughout my workflow — from exploring ideas and architecture to implementation, testing, debugging, and documentation.
I also enjoy building automated workflows that handle repetitive tasks.
Why spend five minutes doing something manually when you can spend five hours automating it?
I'm always open to interesting opportunities, collaborations, and projects worth building.
I promise to ask at least one question before saying "sure, why not?"

Still building. Still debugging. Still pretending this was all part of the plan. 🙃
