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 Nova4AI Command Center Most AI agent
Nova4AI Command Center Most AI agent products give you one assistant and a text box. Nova4AI gives you a fleet you can watch work. Ten specialists run as a team a Researcher, a Coder, a Designer, a QA reviewer, an Archivist, a Prospector, an Optimizer with Navi orchestrating: routing tasks, running standups, pulling teammates into threads with an @mention. Every agent takes voice input. The core of the build is the Live Feed. Agent-to-agent handoffs stream in real time, each carrying a task ID, trace ID, source system, and timestamp. When Kenzo passes work to Relay, you see the message and can follow the trace. Multi-agent systems usually fail silently and invisibly; this one is auditable by default. Around the fleet sits the actual business surface: CRM and lead pipeline, proposals, performance analytics, projects, a shared memory layer, docs, and a skills registry. Agents write real artifacts to real endpoints and integrate outward through MCP and n8n. At the time of this screenshot: 10,983 activities in a day, 5,017 feed messages, 110 tasks open and 42 closed. Built so you can hand work to a team and still know exactly what happened.

Cover image for Fundory — Grant Intelligence for
Fundory — Grant Intelligence for Nonprofits Grant funding runs on a brutal arithmetic: most applications fail, and the ones that fail still cost weeks of a small team's time. Nonprofits with two or three staff are spending that time writing into opportunities they were never positioned to win. Fundory attacks the problem upstream. Instead of helping organizations write faster, it decides what's worth writing at all. Every discovered grant is screened against the organization's actual profile and returned with a fit score, so a 65% never consumes the effort a 91% deserves. The product states its threshold plainly: apply above 85%. The pipeline runs Discovered → Screened → Waiting for Approval → Drafted → Closed, with AI moving work forward and humans holding the approval gate. Drafted proposals carry two separate scores — model confidence and draft quality — because those measure different risks and collapsing them would hide the one that matters. I built the screening and scoring layer, the document and narrative system that grounds drafts in the organization's real history, and the pipeline that keeps 28 live opportunities legible to a team without a grants department. Honest signal over generated volume.

Cover image for Bench — AI Agents for
Bench — AI Agents for Small Teams Solo founders don't lack AI tools. They lack the people who would use them. Most products hand you a blank text box and quietly make you the operator so the inbox still doesn't get triaged and the content calendar still doesn't get built. Bench inverts that. Instead of a chat interface, it's a hiring interface. You staff a bench of role-trained specialists — an Executive Assistant, a Lead Generator, a Social Media Manager, a Marketing Manager — each scoped to real responsibilities with its own tool access and definition of done. They work in the background and report status: working, done, needs review. I built the agent orchestration behind it, the role definitions that keep each specialist in its lane, and the review layer that surfaces anything consequential before it ships. Drafts land in the founder's voice. Nothing gets sent without a human seeing it first. The design constraint throughout was trust. Multi-agent systems fail when they act confidently in the wrong direction, so the product is architected around visible work and cheap correction rather than silent autonomy. Built for the smallest teams to deploy what used to require a payroll.
