BUILDING PEECHZ · STARTUP|BS CYBERSECURITY · 2026

Architecting production systems for the real world. My infrastructure runs in US universities, ranks on the iOS App Store, powers Ghana's national institutes, and scales open-source AI for underserved African languages.

View WorkRead Background

Building Peechz into the proof-of-work talent network for underserved builders: early users, live pitches, university recognition, and production infrastructure are already in market.

[ OVERVIEW ]

I architect and ship production systems. My engineering spans from custom C++ blockchains and open-source AI tokenizers to a government-commissioned digital platform in Ghana.

[ METRICS ]

I build software that survives contact with reality. My work currently processes thousands of records in US universities with zero parse errors, maintains an 10.6% conversion rate on the iOS App Store, and secured 1st place against 800+ engineers at HackOHIO 2025.

Hard technical problems. Real-world execution.

    Peechz

    Web app · AI · Marketplace

    The builder economy has no signal. Resumes reward polish. Code repositories have no audience. Assessment platforms measure the wrong thing.

    Peechz is a video-first talent marketplace where builders showcase real projects through short pitches and get discovered through proof of work. A pipeline of specialized AI agents extracts each builder's tech stack from their pitch and routes it to the exact recruiters, investors, and collaborators looking for those skills. Great work finally has somewhere to go.

    • Sekan Algorithm — 3-agent AI pipeline (Searcher → Detector → Recommender) with Groq inference and sub-second feed ranking
    • PTCHD metric — a view only counts at ≥50% watch time or a high-intent action (save, comment, follow), eliminating vanity signals entirely
    • Atomic Postgres triggers + client-side interaction batching cut API calls by ~95%
    • Video bytes bypass the server entirely via Cloudflare R2 presigned uploads and CDN delivery — zero egress cost

    Founder & Lead Engineer

    Peechz//United States · Remote

    Peechz began at HackOHIO 2025, where it won 1st Place for Most Original Project out of 800+ participants. It is a video-first talent marketplace where builders share short video demos instead of relying on static resumes. Sekan, our 3-agent AI routing system, matches each submission to the most relevant recruiters, investors, and collaborators.

    • PTCHD Metric: A pitch only counts when a viewer watches ≥50% or takes a high-intent action. We optimize for meaningful attention, not impressions.
    • Frontend: Next.js 15 + TypeScript + Tailwind CSS. Singleton client managers with 30-second batch flushing cut API calls by ~95%.
    • Backend: FastAPI + Supabase (Postgres, Realtime, RLS). SECURITY DEFINER triggers maintain counts atomically. Zero race conditions. Real-time layer streams live updates without polling.
    • The Sekan Algorithm: 3-agent AI routing engine (Searcher, Detector, Recommender) on Groq LLaMA 3.3. Multi-key rotation + model fallback.
    • Infrastructure: Cloudflare R2 + CDN. Backend never proxies video bytes. Vercel for web.
