I turn ambiguous business problems into pragmatic architectures — clear boundaries, defensible trade-offs, and systems that scale without over-engineering.
- 🏗️ Solution Architect shipping resilient, multi-domain systems — from on-chain analytics to booking engines, marketplaces, logistics and AI automation.
- 🎯 I optimize for the right trade-off, not the trendy one: I distribute only when a single node genuinely can't cope, and I make every architectural decision defensible with an ADR.
- 🌐 10+ domains, 20+ projects, 10+ clients across Germany and Vietnam.
- 📚 Currently deepening data-intensive-systems fundamentals in public — see Labs below.
- ☁️ AWS-certified · PSM I · comfortable from database internals up to org-wide platform strategy.
Architecture & Data
Cloud & DevOps
Languages & Frameworks
Small, runnable repos where I work through core data-intensive-systems trade-offs. Each ships with an ADR (the reasoning) and a measured result (not just a claim).
| Lab | What it demonstrates | Status |
|---|---|---|
| oltp-to-olap-pipeline | Row-store vs column-store, star-schema modelling, and what ETL is really for — with a benchmark you can reproduce | ✅ Live |
| storage-compute-separation | Cloud-native storage/compute split, with a cost model showing when it's cheaper than a coupled DB — and when it isn't | ✅ Live |
| scale-up-before-out | Measuring how far a single node goes before you pay the distributed-systems tax | 🔜 Planned |
| privacy-by-design-reference | GDPR data-subject rights (access, erasure, portability) as an architecture concern | 🔜 Planned |
