My obsession is simple: help build the best teams. I direct AI systems to make that real — for how I hire, evaluate talent, and operate at scale. Not demos.

01 [ABOUT]

I help build the best teams

I started in Human Resources and moved deliberately toward AI engineering — not to become a developer, but because the systems I needed to build great teams didn't exist yet. So I direct AI to build them.

→Architecting AI systems that make hiring and team decisions faster and more accurate — orchestration, evaluation loops, audit trails.
→Directing AI-built software end-to-end to solve real team-building problems — product thinking, specification and verification, not hands-on code.
→Integrating LLMs into real operational hiring workflows, not just demos.
→5+ years running real recruitment operations — so I know exactly what makes a team work, not just what looks good on a slide.
02 [PROJECTS]

Proof, not theory

Everything here exists because it makes a team's hiring sharper, faster, or more reliable — not because it looks good in a portfolio.

Team Builder

A tool for a question I ask on every project: who should do what, given what this specific challenge demands? Load a team's soft skills and preferences, describe the project ahead, and it proposes role assignments — optimizing for fit and for people's happiness as two separate, visible dials, not one hidden average. Runs entirely in the browser: nothing typed in ever leaves the visitor's machine. Free for any HR team to use.

AI Governance Harness

An operational framework for running autonomous AI agents safely in production: scoped permission boundaries, a kill-switch, versioned decision logs, rollback strategy, and staged promotion gates before any agent runs unattended — because the tools behind a team deserve the same rigor as the team itself.

03 [WHAT-I-BRING]

Know-how, not a service menu

This is what actually goes into building a great team — the operational skill set behind everything above.

Technical Recruiting, IT Market

core specialty

5+ years recruiting IT profiles end-to-end — sourcing, technical screening, interview loops, offers, and onboarding. ~110 recruitment processes in 2025 alone, 200+ interviews conducted, 45 hires delivered across technical, leadership, and business roles for 10+ product and consulting teams. I know how to evaluate a technical profile I don't personally code — through structured screening, the right interviewers, and reading signal from how a candidate reasons, not just keywords on a CV.

AI Governance & Agent Orchestration

core discipline

Designing operational frameworks for autonomous AI agents: permission scoping, kill-switches, versioned decision logs, rollback strategy, staged promotion gates, and cross-provider model fallback so agent work stays safe running unattended.

Spec-Driven AI Delivery

how I build

I don't write code by hand. I direct AI systems to build production software through precise technical specification, staged builds, and rigorous, evidence-based verification — I know exactly what "done" looks like before I delegate it.

Multi-Agent Evals & Cost Discipline

quality control

Evaluation loops that check AI output before it ships, plus cost/risk-aware model selection — fallback ladders and escalation rules instead of trusting a single model blindly.

HR Domain Fluency, Applied

the edge most builders lack

Beyond recruiting: onboarding, employee engagement, and day-to-day HR operations experience shapes how I direct AI systems — I know what actually changes a hiring or people team's daily workflow, not just what looks good in a demo.

Recruitment Automation, in Production

shipped, not theoretical

Automated workflows (Power Automate, Microsoft connectors) already running inside a real hiring operation: email triggers, candidate follow-ups, and recruitment-data traceability across the pipeline.

Data Fluency

in progress

Building working fluency in Power BI and HR analytics to ground AI-directed automation in real operational numbers, not assumptions.

04 [WHY]

Why this isn't just a job to me

I've watched good teams get built by accident and bad ones get built on purpose — by whoever happened to be understaffed that quarter, not by anyone who actually thought about it. That gap is what I care about closing. Everything else on this page is downstream of that.

→A team isn't a headcount number, and a hire isn't a checkbox at the end of a funnel. A pipeline is a series of judgment calls — most hiring tools are built to hide that, not support it.
→I don't build software to prove I can direct AI. I build it because the tools recruiters get handed were built by people who never sat in the chair, and it shows in what gets missed every day.
→Technology serves people, not the other way around. If a system makes a hiring decision faster but worse, it's not done — it's just fast.
→I'm not trying to sell you a SaaS on this page. Selling comes later, if at all. What I actually want is to compare notes with anyone building something real — a team, a product, a company — because how you build the team is the ceiling on everything else you build.
