I help startups and scale-ups ship and run production systems — from cloud infrastructure to product — without the cost and lead time of an in-house senior hire.
15+ years designing, building, and operating software at scale. Through Cellihub, my engineering studio, I work directly with founders and teams worldwide — billed in USD / EUR. No layers, no juniors learning on your budget, no over-provisioned cloud bills.
| ☁️ Cloud & Platform Engineering | AWS, GCP & Azure architected as code — multi-account governance, Terraform / OpenTofu, secure networking and landing zones that scale without bill shock. |
| 🔐 DevSecOps & Secure CI/CD | Pipelines that ship fast and safely: automated SAST/DAST (SonarQube, Semgrep, Dependency-Track), supply-chain checks, zero-downtime deploys. |
| 🧩 Full-Stack Product Engineering | Go services + React / TypeScript / Tailwind interfaces, designed in Figma — MVPs, internal tools, and modernizing legacy stacks. |
| 📈 Reliability & Cost Engineering | SRE + FinOps in one practice: observability, load testing on Kubernetes, incident readiness, and infrastructure tuned so you pay only for what you use. |
🏗️ Proof of work — renthci
A multi-tenant property & asset management SaaS I designed, built, and operate end to end:
- 💸 Right Price cloud infrastructure with Right Sizing
- 🧱 100% infrastructure as code
- ⚡ AWS Services — efficient by design
- 🔑 Zero static keys — CI/CD via OIDC
Disciplined automation and lean architecture beat over-provisioning — every time.
Plus AI/ML with TensorFlow when a problem genuinely calls for a custom model.
- AWS Certified Cloud Practitioner — Cloud fundamentals & operations
- LPIC-1 — Linux Administrator
- LPIC-2 — Linux Engineer
- HashiCorp Terraform Associate — Infrastructure as Code
- TensorFlow Developer — Neural network design & training
The easiest way to start is a focused Technical Audit — a clear, prioritized roadmap for your cloud, pipeline, or codebase that's yours to keep, with no strings attached.
