Ohayou, watashi wa Kariebi 👋

I'm a full-stack engineer with 5+ years building production web and mobile applications across fintech, real estate, Web3, and SaaS. I'm finishing a B.Eng. in Mechatronics Engineering at FUTO, which means I think about software the way an engineer thinks about systems: what breaks under load, what doesn't scale, and where the real bottlenecks are.

I currently work at Execufy, where I'm migrating infrastructure, cutting costs with Redis + Upstash, and helping architect a CRM + Marketplace SaaS platform from scratch.

What I've shipped

  • CRM + Marketplace SaaS : Architected and worked hand-in-hand in development from scratch at Execufy, designed to support 100K+ concurrent users
  • Real-time infrastructure migration : Replaced Convex with a Redis + Upstash pipeline, cutting projected infrastructure costs by over 40%
  • Monorepo migration : Reorganized a multi-package codebase, standardized tooling and eliminated cross-package dependency drift
  • Web3 transaction workflows : Built on-chain automation on the COTI blockchain for decentralized settlement
  • Geolocation claims feature : Launched at Homiee.AU, contributing to 10% growth in monthly active users
  • Telegram mini-app : Boosted user engagement by 35% through targeted UX and performance work at Musigwe Labs
  • AI sentiment analysis : Developed market intelligence modules for trade signal generation at Codetratives

Currently exploring

  • Infrastructure design patterns for high-concurrency SaaS
  • End-to-end type safety with oRPC across full-stack monorepos
  • Upstash and edge-native real-time data pipelines
