Hard systems
At EIBGroup, I work on hardware-software integration for unmanned aerial systems running over satellite communication networks: real-time monitoring across Go, Python, and JavaScript, plus on-prem data center DevOps.

Inioluwa John Adeyinka
I turn sharp, unglamorous problems into software people actually use. Job seekers needed the truth about their CVs, so I built DR CV. Teams needed answers without another dashboard, so I'm building DEX. The through-line is simple: make the hard thing usable.
current proof
2,000+
DR CV users in the first month. A real pull signal, not a portfolio ornament.
01
Founder
DR CV crossed 2,000+ users in its first month.
02
Product
DEX puts analytics inside Slack and Teams.
03
Systems
UAV, KYC, ML, and infrastructure work in production.
02
Founder work
I founded DR CV, which crossed 2,000+ users in month one. I'm also building DEX, AI analytics that lives where teams already talk.
03
Public trail
The open-source thread keeps running: Stellar, Starknet, AI/ML experiments, legal-tech, edtech, and 80-plus public GitHub repositories that show how I learn by building.

Featured project
Dr CV
Diagnosis, not flattery — recruiter-grade CV feedback for African professionals.
Founder project. Dr CV gives any African professional an honest CV diagnosis in about 30 seconds, then sells the fix: rewrite, matched roles, tailored applications, and interview prep. Crossed 2,000+ users in the first month, with a consumer wedge that also builds structured, quality-scored candidate data for the long-term talent layer.

DEX
AI analytics that lives in Slack and Teams.
An AI-powered data analytics platform that lives inside Slack and Microsoft Teams. Connect a database or upload a file, mention @DEX in a thread, and get a chart and a narrative back in seconds — no SQL, no dashboards. Founder project, currently in private beta. All tiers free through 2026.

UAV & Satellite Communications
Real-time control planes for unmanned systems over unreliable links.
Hardware-software integration for unmanned aerial vehicle operations over satellite communication networks at EIBGroup. Built real-time monitoring applications and low-level system interfaces in Go and Python, with on-prem data center DevOps for mission-critical availability. The challenge: reliable command and data transmission in environments where connectivity is unreliable by definition.

TellerOne AI/ML Platform
Face recognition, liveness, and KYC for a Nigerian fintech in production.
Production face-recognition, liveness detection, and KYC infrastructure for a Nigerian fintech. Built and deployed real-time face-match and document verification, plus transaction anomaly detection that materially reduced fraud incidents. Models have run against tens of thousands of verifications.

TeacherToolz
Edtech, co-founded out of Naija Hacks 2018; international seed funding; 90+ educators.
Co-founded an edtech startup out of the Naija Hacks Hackathon. Built a suite of tools for classroom management, lesson planning, and student engagement; scaled to 90+ educators across Nigeria. Secured 2,000 CAD seed funding from the Dunin-Deshpande Queen's Innovation Centre at Queen's University, Canada. Partnered with National e-Government Strategies (NeGST) to distribute to public school teachers. Featured on Voice of America. Wound down 2020.

Plus 80+ public owner repositories across AI/ML, Web3 (Stellar, Starknet), legal-tech, edtech, and infrastructure tooling; the trail is public enough to inspect, not just polished enough to present — see GitHub.
01
Build until the idea resists.
The repo count is not the point. It is the residue of testing protocols, papers, product ideas, and unfamiliar systems by making them concrete.
02
Keep the model close to the mess.
AI work becomes real when it has to survive bad inputs, weird users, cost constraints, payment flows, and production support.
03
Distribution is part of engineering.
A product is not finished when it works locally. The copy, the first useful result, the upgrade path, and the operational loop are all part of the system.
