RMZI.tech
Staff-level engineering, engagement-sized.
Short-term full-stack consulting for startups that need staff-level delivery — migrations, MVPs, AI features, and DevOps — without a permanent hire.
What I do
Engagement-sized full-stack work
-
Short-term full-stack delivery
Ship product features end-to-end in weeks to a few months — TypeScript/Node, Go, Python, React/Next, and Postgres — without an open-ended staff-aug commitment.
-
Platform modernization & migrations
Restructure mid-stream: MongoDB → Postgres, sparse Lambda → dedicated services, monolith splits, and measurable latency or support wins.
-
AI-assisted product features
Practical LLM features — support chat, agents, retrieval — with production guardrails, observability, and clear ownership boundaries.
-
DevOps & infrastructure
AWS/GCP, Terraform/OpenTofu, CI/CD, and the static-site + OIDC deploy patterns I run for my own products and client sites.

When to hire a short-term staff engineer
Open-ended staff-aug is not always the right lever. When a weeks-to-months engagement with a principal/staff-level engineer pays off for startups.
