Cover image for Here we go!

Android Notes -

Here we go! Android Notes - Notes and meeting summary app. Almost as good as Granola but built on Bubble. Speaker labels for multiple parties in convo, chat with note, summary, next steps, status, folders, just about everything you could want. But more importantly... Note Intelligence! Draw correlations between your notes you maybe were not aware of (why I built the app). Started this in May of last year and decided to dust it off for the challenge. Sweet promo vid coming soon! Will share the link in a few. Thanks!

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 Finally took time to document my work properly. Last decade ...

Finally took time to document my work properly. Last decade building products bridging physical and digital: connected medical devices, 3D printers, smart implants, consumer electronics. Zero-to-one builds, scaling teams, shipping things that matter. This year I went deep: detailed case studies for Hero Health, MakerBot, and Canary Medical. The wins, the process, what I actually did. Years of work condensed into a few scrolls. Also added 2025 builds—including Superstash, a native iPadOS app I designed and developed solo using AI-assisted tools. Design to code, at a pace that used to require a team. If you're curious what a decade+ of product work looks like: https://jneal.vercel.app

Alright, here we go. I've been working solo on v2.0 of my personal iPad app for inspiration and daily organization called SuperStash. Using Figma MCP, Cursor, and Claude Sonnet 4.5, I'm currently beta testing to finalize before launch. It's an infinite canvas tool (draw anywhere with Apple Pencil) that includes a built-in web browser with preloaded inspiration sites. Save images to the canvas, organize them, and share. Stay on top of your to-do list (syncs with Reminders) with built-in widgets and a Pomodoro timer. If you're interested in testing, please DM me and I'll send you an invite. Just getting started with Contra, so any helpful hints would be great too!

PrintShop is my all-time favorite consumer experience we brought to life at MakerBot. As the company pushed 3D printing into the consumer market with the new Mini Printer, we developed an end-to-end iPad app that made 3D printing accessible to everyone. Users could browse top models from Thingiverse, customize wearables, and purchase high-quality models from our digital store—all without any modeling skills required. The icing on the cake was Shape Maker, a feature that let anyone draw on paper, snap a photo, and transform it into a 3D model. Check out the video featured on my profile to see it in action.

In terms of social impact, Hero helped members live their best lives by ensuring they took their medication on time. I joined the company to design and develop the consumer experience from end-to-end with a tight-knit team right from the start. We focused on two key sprints: Setup: Onboarding accounts, setting up schedules, and loading the medication dispenser with pills. Day-to-day usage: How members get notified when it's pill time, dispensing meds, and what happens if they miss a dose—cue the caregiver experience. Incredibly complex digital/physical interactions made simple. Sometimes when you're grinding, you don't realize the impact until a member reaches out and says: "I want to say how this machine has changed my life! Because of Hero I've not had a seizure in months."
