Site Lead, Google Ghana · Accra
I started at Goldman Sachs, spent a decade at Google, and now lead Google Ghana, where I work on AI research for African languages and mentor engineers. Nights and weekends, I build apps.
I started at Goldman Sachs in New York, then spent a decade at Google working across Wallet, Search, and Ads. Now I lead Google Ghana, where our teams work on AI research for problems like flood forecasting, maternal health, and speech data for African languages.
Outside of Google, I run Mina Logic, an app development studio. I'm the CTO of Otto Couture, the bespoke fashion house founded by my best friend Asafo-Adjei Amoakohene — when he asked me to build an app for his tailoring business, that project grew into Bespoke, a management platform now used by thousands of tailors. I also built Lapse, which turns scattered photos into face-aligned timelapses, right on your phone. My latest app, Juma, helps independent service businesses in Ghana organise jobs and invoices. It is available for Android in Ghana.
I'm also a dad. That's the job I take most seriously.
Ideas are cheap. Bespoke, QuickMaths, and Lapse all started as side projects, and all made it to real users.
The research we do in Ghana — flood forecasting, maternal health, language — starts with problems that matter here.
Mentoring engineers, volunteering with Citizen Schools and Code Nation, and funding the computer lab named for my father.
The résumé, in chronological order.
Where it all started. A great foundation that shaped my curiosity and gave me a global perspective early on.
Double-majored in Electrical & Computer Engineering and Computer Science — half hardware, half software.
Started my career on Wall Street, building technology at Goldman Sachs. Learned how to ship in high-stakes environments where the code you write really can't break.
Helped build the systems that authenticate and secure financial transactions for millions of users. Co-authored a defensive publication on "Authenticating Financial Accounts" — solving real-world payment security challenges.
Worked on the product people use every day without thinking about it. Information retrieval, user intent, and a lot of edge cases.
Built advertising technology that runs at global scale — the systems that keep most of Google free.
Leading Google's presence in Ghana. Overseeing AI research that addresses Africa's unique challenges — from maternal health to language preservation. Partnering with the Ministry of Education to integrate AI fluency into Ghana's national curriculum. Building a community of developers and researchers at the Accra AI Community Center.
Speech AI mostly doesn't work in the languages a billion Africans speak. This work is about closing that gap.
Co-authored an open-source speech corpus supporting 20+ Sub-Saharan African languages. What started as an open-source toolkit for crowdsourcing speech data — now used by organizations like Sunbird.AI to collect speech for East African languages — planted the seeds for WAXAL (pronounced "wa-haal"), which has grown into one of the largest multilingual African language datasets ever published.
Co-invented a system for securely associating payment accounts with users for online and mobile transactions. The system uses authorization holds and credential verification to authenticate account ownership — foundational technology for Google Wallet/Payments.
Products and businesses I build alongside my day job. Juma is the latest, for independent service businesses in Ghana.
For plumbers, cleaners, technicians and other independent service businesses in Ghana. Keep jobs, customers and invoices in one place, and record cash you’ve already received.
Available for Android in Ghana. The iPhone version is awaiting Apple review.
AI-powered app development studio. We build custom web apps, mobile apps, and SaaS platforms — from idea to live product in weeks, not months.
A management platform for bespoke tailors, born from building an app for my best friend's tailoring business. Snap a photo of handwritten measurements and the app digitizes them; orders, payments, and customer updates live in one place.
Turn scattered photos of a person into a smooth timelapse. Lapse finds the face in each shot and aligns the eyes across frames — pick the pacing and a soundtrack, then export. Everything runs on-device: no account, no uploads.
AI-powered financial tools for UK accountants. Scan bank statements, auto-categorize transactions with HMRC categories, and export clean data for MTD-compatible software. Free forever.
Bespoke African fashion house founded by my best friend Asafo-Adjei Amoakohene — handcrafted kaftans, agbadas, and modern menswear from Labadi, Accra. I run the technology side, which is where BeSpoke came from.
"If something must be done, it must be done well."— Emmanuel Nii Azuma Nelson, my father
When I was young, my dad gave me his work computer and went back to using a typewriter. That single act changed my life. It gave me access to a world of possibility that shaped everything I've built since.
The Emmanuel Nii Azuma Nelson Computer Lab at Liberty No. 2 High School in Adabraka, Accra, is my way of passing that gift forward. Dedicated in May 2026, the lab gives students access to computers and digital learning resources.
Volunteer mentor — teaching coding and STEM apprenticeships to middle school students
