Selected work
Real products.
Recognizable names.
From private social networks to AI hiring platforms to luxury fitness apps. Built across teams, industries, and tech stacks.
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.
Real-time encrypted messaging + feed algorithm. The two hardest things to get right in social apps, shipped in one product.
Health & Wellness · Mobile App
myNutrafol App
Companion mobile app for Nutrafol, the #1 dermatologist-recommended hair growth supplement brand. Built as part of a larger engineering team. The app gives subscribers personalized progress tracking, daily habit tools, expert consultations, and an exclusive rewards system.
Nutrafol is trusted by 1,500+ physicians. The myNutrafol app is their subscriber experience layer, built for scale and consistency.
Fitness Tech · Member App
Midtown Athletic Club
Mobile app for one of the US's premier luxury athletic club chains. Built as part of a larger team. Members use it to book classes, reserve amenities, manage accounts, discover events, and access exclusive offers across multiple club locations.
Multi-location, multi-amenity booking platform serving thousands of premium members across club locations in the US.
AI SaaS · Team Lead
EnergyHire
Led development of the main platform for an AI-powered energy sector talent marketplace. EnergyHire connects energy companies with specialized professionals using ML-driven matching, a job description generator, resume scoring, and candidate-employer fit algorithms.
Team lead on the core platform. AI-driven recruitment built for an industry that generic job boards don't understand.
SaaS · Admin Feature
Preppr.ai
Built a Free Trial Access Management system with full admin controls: approve/deny requests, automated email notifications, access code generation, and a dedicated super admin panel for staff with role-based access.
"Well damn, you went above and beyond. Engineer of the day." - Justin, client
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.
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.
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.
“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.
“You are the best engineer with design skills that I know. Ships clean code and thinks about the full picture.
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.
