Cover image for Led delivery of a cloud-native

Led delivery of a cloud-native K-12 student wellness platform that helps counselors monitor wellbeing, surface at-risk students, and act early—balancing product velocity with FERPA/COPPA-aware design and multi-tenant isolation (API RBAC, PostgreSQL RLS, district-scoped analytics). → Owned technical direction and delivery rhythm across a TypeScript monorepo (pnpm/Turbo): backend API, web app, shared packages, DB migrations, CI/CD gates, and staged deploys to GCP (e.g. Cloud Run), aligning engineering work with roadmap and release risk. → Orchestrated an AI assistant for counselors on Google Vertex AI (Gemini): system prompts, safety settings for K-12, function-calling tool design, multi-round tool loops, and strict separation so UI widgets render from verified tool results—not model hallucinations—with tracing/feedback hooks (e.g. Langfuse) for quality and auditability. → Drove access-control and compliance posture for sensitive student data: role/permission middleware, tenant-scoped queries, and defense-in-depth database policies—documentation and evidence suitable for enterprise security reviews (e.g. SOC 2–style narratives). → Partnered on product and program management: phased feature rollout, PR/branch discipline, and clear ownership of scope vs. risk so pilot schools could onboard without compromising data boundaries. → Shaped integrations and platform boundaries: Firebase auth, Neon PostgreSQL + Drizzle ORM, real-time patterns, BigQuery analytics isolation, and operational practices (testing, lint, type-check) that keep the stack maintainable at scale. → Established a disciplined, AI-accelerated delivery model—not ad-hoc prompting: Cursor rules and Claude skills/agents for repeatable workflows; Husky + lint/type-check/test gates; GitHub Actions CI/CD; Cursor Cloud Agents for automated PR review; and daily monitoring of E2E, coverage, and critical issues—owning AI-orchestrated implementation while enforcing accuracy, consistency, and observability

Cover image for A few months ago I

A few months ago I ran into a problem while working on a client’s HubSpot site. We needed to update URLs across hundreds of blog posts. Coming from a WordPress background, I assumed this would be simple. HubSpot is an incredibly powerful platform…surely there must be a way to do a bulk search & replace across content. Turns out there isn’t. If you need to update something across hundreds or thousands of records, and there’s no safe, simple way to do it. So I decided to build the tool I wished existed. After using it internally, it felt obvious that other HubSpot teams probably need this too. Last week we opened it up publicly: SearchReplace.com (http://SearchReplace.com)If you manage HubSpot and have ever needed to update something across a lot of records, this might save you a lot of time (and a lot of stress).

Cover image for As a developer, I love making little tools like like Chrome ...

As a developer, I love making little tools like like Chrome Extensions, so when I saw a posting on Contra for a real estate scraper, instead of just sending a proposal - I built the actual tool instead. It's a one-click Chrome Extension that scrapes property listings from InvestorLift and sends them straight to Airtable. No manual steps or exports. Just one-click data capture. It's 95% complete and already working on live listings. Whether this converts to a client or not, I had fun solving the problem. Sometimes the best way to show you can do the work is to just… do the work.
