Summary

I'm a senior product designer and design engineer. I design in Figma and build in production code, so I can take a product from a customer problem to a shipped release. I have five years in product design, the last three and a half at MTN Nigeria in telecoms and payments.

At MTN I lead design on myMTN, MTN's self-service app, which passed a million users and carries ₦6–7B in revenue a month. There I cut airtime and data purchase drop-off by 20%. I also led design of the MoMo app for MTN's bank, where onboarding drop-off fell 30% and transaction success rose 20%, and redesigned MoMo Corporate on my own. I own components in Raanaa, MTN's design system, which lives in code and has cut design-to-production time by about 40%. Outside MTN I've built four products end to end with Next.js, Supabase and AI coding agents, two of them in real use.

Experience

Senior Lead Product Designer · MTN Nigeria

Apr 2023 – Present

Telecoms and payments · Lagos

myMTN app MTN's self-service app · Lead designer · ongoing

  • Lead myMTN's design through its 1 million user milestone and today, for an app that carries ₦6–7B in revenue a month.
  • Cut airtime and data purchase drop-off by 20%, so more customers who started a purchase finished it.
  • Grew app traffic 25% and usage 30%, using usability sessions with real customers and A/B tests to choose what to change.

MoMo PSB app MTN's bank · 2023 – 2024Case study

  • Led design of the MoMo app for iPhone, Android and web, for a bank licensed by the Central Bank of Nigeria, and designed almost all of it.
  • Cut onboarding and KYC drop-off by 30% with a redesigned sign-up, so more customers reached an active account.
  • Raised transaction success by 20% by reworking payment flows, confirmations and the error states of 13 flows.
  • Lifted engagement 25%, adding about ₦150M in transaction volume a month and supporting ₦800M a year.
  • Shipped a bank network monitor that warns customers a receiving bank is struggling before they send, and owned 64 features after launch.
  • Worked in an agile team with product owners, business analysts, a scrum master and developers. I turned each request into a Figma page that developers built from, then checked the build with QA testers in sanity testing.

MoMo Corporate Business accounts · 2024 – 2025

  • Led the MoMo Corporate redesign as its only designer, raising business account invitations by 20%.
  • Shortened the application: each key person's details went from three form sections to one, and low-risk businesses no longer need an operating licence or SCUML.
  • Worked with compliance and onboarding teams, who both sign off every business application, to meet CBN requirements.
  • Added PEP and sanctions screening for compliance, and a dashboard that shows staff where each application is stuck.

Raanaa design system One of five designers · 2023 – PresentCase study

  • Used by MTN's whole design team, about 15 designers, and 40 developers across more than 20 products: 47 components matched in Figma and code, and over 1,000 variables.
  • Cut design-to-production time by about 40% (our senior developer's estimate) by keeping the system in code. I owned Badge, Modal and Table from Figma to code.
