JengaTrack
Construction ops · 2025
A WhatsApp-first construction workflow for Uganda: a Supabase office dashboard paired with Twilio-powered field updates and photo logs, so supervisors don't need a new app.
Also built: PRISM (social platform moved off Base44 onto Node, Firebase and Supabase), TripSwap (bilingual travel marketplace with PayPal escrow on iOS), Laid (real-time speed dating PWA), Retainly (Shopify loyalty app), FIDELIOR (Notion to Base44 sync), CBP AI (AI assistant and directory), TOPAZ 2.0 (dance competition platform) and Evry Health (production email development).

04 / About
A pragmatic partner
for complicated ideas.
I'm Oyinloluwa Daniel, founder of Cipher Development. I work with solo founders, agencies and growing teams to turn unclear product ideas into focused, production-ready software.
That can mean shaping the scope, designing the flow, shipping the full-stack application, or making a half-built product stable enough to grow. I care about fast movement, clear communication, and work that holds up after launch.

Move fast
Short loops and a working build early, so decisions happen in days, not weeks.
- (02)
Say it plainly
Clear updates and honest trade-offs, with no surprises about scope or timing.
- (03)
Build to last
Work that holds up after launch, not just on demo day.
05 / Receipts
Words from the
people I built for.
“Dan is the absolute best! If I could hire him full-time, I absolutely would. He is communicative, creative, and completes work quickly and accurately. He has taken my application from a little idea to a fully functional program in the short time we have worked together. He works SO hard and is so respectful. I highly recommend working with him!”
