Act I

Selected work

Product, content and business. Four things I have built or run, and the field years that came first.

Reel 01 / Product / 2023–2025

Yuvlex

Product owner, UI and UX design

Students in Nigerian public universities queue to check results by hand. Yuvlex takes one advising sheet and emails every student their own result, so course advisers stop sending records one by one.

  • Designed the interface and the whole sending flow
  • Led developers, researchers and data analysts from concept to implementation
  • Turned what advisers and students needed into product requirements

  • Recruitment from sourcing to onboarding

  • Procurement and day-to-day administration
  • Refresher training for staff

Enactus

Project head

Clean water, for less.

Led a research team looking for a cheaper way to purify water, so that people in rural communities could afford it.

Act II

The person

Elvis Chilaka at his desk, in a cap and glasses, thinking with his hand on his chin

I started out servicing tools that work down an oil well. Now I work on things people open on their phones.

I'm Elvis Chilaka Okechukwu, based in Abuja. I studied petroleum engineering at the Federal University of Technology Owerri and graduated in 2023, after an internship on Halliburton's wireline team.

The field taught me to check everything twice and to fix the handling problem nobody else has time for. I carried that into product work at Yuvlex, where I designed the experience and led the team, and into Grevix, the company I own.

On the side I make Clio's Trove, a channel of African folktales. Different medium, same job: work out what the audience needs and get it to them.

  1. EnactusProject head, water purification research
  2. HalliburtonWireline engineering intern
  3. FUTOBachelor of Engineering
  4. YuvlexProduct owner until 2025
  5. Clio's TroveChannel launched
  6. GrevixOwner, to date
