What I bring to a leadership team
Product direction, platform architecture, and delivery discipline — held by one owner instead of three.
Platform & Cloud Architecture
Distributed systems designed for throughput, clear boundaries, and graceful failure.
- Python (FastAPI) · Go
- gRPC · Protobuf · PostgreSQL
- Azure · Cloudflare · Linode
- Multi-tenant SaaS foundations
AI & Engineering Enablement
Agentic tooling and DevSecOps practices that shorten the path from idea to production.
- Agentic AI execution (E2B, vLLM/Ollama, OpenCode)
- SAST · container scanning · CI/CD
- Grafana observability
- Developer sandboxes
Selected projects
Systems built to survive production
Representative work adapted from real engagements. Full case studies are in progress.
01Case study coming soon
Enterprise SaaS Architecture
A multi-tenant platform where Python and Go services meet over gRPC contracts. Built for high-throughput APIs, strict service boundaries, and predictable behavior under load, on Azure PostgreSQL.

Designing for Failure: Resilience Patterns for Distributed Systems
The resilience patterns I reach for when a service absolutely cannot go down — and the trade-offs nobody mentions.
AI AgentsDevSecOps
Agentic Coding in Practice: What Actually Works
A grounded look at AI coding agents: where they help, where they hurt, and the guardrails that make them useful.
