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 New tool alert!
I built html.contact

New tool alert! I built html.contact (http://html.contact) for devs, designers, and freelancers who need a contact form without setting up a backend. Create an endpoint. Paste the form URL. Receive submissions. That’s it. No SMTP. No Zapier. No server. No DNS setup. Works with plain HTML, Astro, Next.js, Webflow, Framer, Carrd, WordPress, Shopify, and any site that can send a normal HTML form. The free tier includes attachments, exports, up to 10 verified recipients, unlimited forms, CC/BCC fields, and API access. Why I built this: Getting form submissions into an inbox has annoyed me since the early 2000s. Ideally it would not take a backend, DNS setup, or a bunch of glue just to make a contact form work. With all the static sites, client sites, and AI-built sites being shipped right now, I wanted something simple I could use over and over again. Would love feedback from anyone building websites for clients or shipping quick landing pages. If you try it and actually use it, DM me what you’re building. I’ll upgrade the first few Contra folks to lifetime Pro on the house.
