Social Network · iOS & Android

TAPP Social

Private, invite-only social network built for real privacy: no ads, no public search, no data selling. I led development of the mobile apps across both platforms, building real-time chat with end-to-end encryption, the social feed algorithm, and the core social graph.

Web Game · Mobile-First

The Movie Chain

Mobile-focused web game built for a repeat client. The same client who hired me 4 years earlier for a native mobile game came back specifically to build this. A trust signal that speaks for itself.

ReactTypeScriptMobile-First WebGame Mechanics

Repeat client, 4 years later. First a native mobile game, then a web game. Same engineer, different platform, same trust.

SaaS · Founder

tem mimo

Multi-tenant loyalty SaaS platform I founded and built from scratch. Handles multiple businesses, multiple loyalty programs, and real user data on one platform. Every architecture decision, product choice, and line of code is mine.

Multi-tenant SaaSReactRailsPostgreSQLFounder

Built as a founder, not a contractor. I know what it costs to own a product, and build accordingly.

Technical Writing · Series

DDD Clean Architecture in Flutter

Published a multi-part technical series on Domain-Driven Design and Clean Architecture in Flutter, covering Presentation, Domain, Infrastructure, and Application layers through to Dependency Injection.

Engineers who write about architecture think about it differently. I don't just build. I understand why the decisions matter.

Trusted by founders, teams, and engineers

Clients remember.
They come back.

Real feedback from founders, CTOs, and teams who've shipped with me.

We needed a trial access system with admin controls, fast. Nifemi built the whole thing end-to-end — approve/deny flow, email automation, role-based access — and delivered ahead of schedule.

JustinClient · Preppr.ai

Our legacy frontend was killing conversion. Nifemi rebuilt it in Next.js — cut load time by 40%, and we could finally iterate. The difference was night and day.

The Movie Chain

I worked with Nifemi 4 years ago on a mobile game. When I needed to build a new web game, he was the first — and only — call I made. He rebuilt the concept from scratch, delivered in ~6 months, and we've had an ongoing retainer ever since.
