Project: EMBER — weather-aware fire triage
booting control plane.
I design and build AI agents, LLM routers & RAG systems on cloud and data platforms.
I sketch the architecture first, then build it, then measure whether it actually works. This is where I share what I’m designing, building, breaking and learning: open-source labs, hackathon builds, and notes for fellow tinkerers. 10+ years of cloud and infra under the hood.

Each card has the key design decision, straight from the repo’s README.
Routes each prompt to the cheapest model that can handle it. 98% routing accuracy on 100 labelled prompts vs 62% for keyword rules, and about 27–29% lower cost than sending everything to gpt-5.4 (measured in the repo; 98% is optimistic until a held-out split is added).
Design: An LLM classifier (gpt-5-mini) picks one of four model tiers; its JSON is validated against policy rules, and invalid output falls back to the strongest model. A 100-prompt golden set drives the tuning loop.
A RAG build taken through seven phases, with a walkthrough, architecture diagram, and demo video.
Design: Hybrid BM25 + vector search (alpha 0.5, top 30), a cross-encoder reranker keeps the best 5, superseded docs are filtered out, and a CI eval gate fails any PR that drops retrieval quality.
Bahasa-first AI fire commander for village brigades during Southeast Asian haze fires: ranks satellite detections by spread risk, with a volunteer app and supervisor console. Submitted; awaiting results.
Design: Agents fuse reports from many phones into one shared incident; a human supervisor approves every high-stakes call, and the WITHDRAW-upwind safety rule is deterministic code, not model output.
Snowflake CoCo CLI fraud case copilot: transaction in, policy match, risk score with citations. Risk / Fraud / Regulatory track.
Design: Streamlit in Snowflake: transaction id → customer context → rule matches → risk score with policy citations, then a case and a native Snowflake alert trail.
A CI eval gate that checks agent traces for faithfulness, tool success, and PII leaks before a change ships.
Design: Deterministic, fixture-first checks on JSON traces that exit non-zero, so GitHub Actions or Azure DevOps can block the merge.
Turns failed Azure Pipelines and GitHub Actions logs into structured RCA JSON, with human approval required before any fix.
Design: Logs become structured RCA JSON with an explicit human_approval_required flag, so it’s safe to wire into an agent.
iac-guard-mcp (Terraform/Bicep diff review), azure-ops-mcp (Key Vault compare, ADO diagnose, dry-run + audit), lakehouse-insights-skill, and kc-mcp.
Design: iac-guard uses Checkov when available and falls back to built-in regex policies, returning structured findings JSON that agents can cite.
Hub-and-spoke Terraform modules for Azure networking, Python Key Vault automation, and multi-CI demos across GitHub Actions, Azure DevOps, and GitLab.
Design: Separate hub and spoke Terraform modules plus an example that wires them together: a foundation to extend, not a full landing zone.

04 / About
I’m a solutions architect who still writes the code. I design and build AI agents, LLM routers and RAG systems on cloud and data platforms, after 10+ years in cloud and infra on Azure and AWS. These days it’s agents, evals and making models cheaper to run. Some of it runs in production at my day job; the rest lives on GitHub.
I started out automating VMs by the thousand, then moved into cloud migrations, landing zones and Terraform pipelines, then DevOps: Kubernetes, observability and lots of IaC.
Now I design and build the AI layer. At my day job that means an Azure AI Foundry gateway that governs how AI gets used, and AI agents on Databricks, Snowflake and Sigma that save people from manual analysis. I care about evals and operational readiness more than demos.
On my own time I design and build things to learn, starting from an architecture diagram: an LLM auto-router that picks the cheapest model that can do the job, a production-grade RAG, MCP tools for ops, and hackathon builds like EMBER. If it breaks, I write down why.
Pick a tool to light up the projects, hackathons and production work that use it.
05 / Running in production
An Azure AI Foundry gateway I designed and implemented to manage, monitor and govern AI solutions: one place for model access, oversight and control.
AI agents I designed on the data platform that cut manual analysis for ops and business teams, plus AI for analytics and operational insights.
Evals, testing and operational readiness for AI apps; trying out Cursor and MCP with security and configuration first.
Scope only. Internal details and numbers stay at work.
