I design systems that have to stay correct in production, and I build them across software engineering: web, mobile, desktop, CLI tools, security, and the pipeline that ships them.
Build
Apart from a consultation
A session is a review. These are the things I build, under a separate agreement once the shape of the work is clear.
Web applications
Browser products with the system behind them kept correct.
Mobile applications
Phone applications on the same system as the web.
Desktop software
Installed products that still have to stay correct after the first release.
CLI tools
Tools you run from a terminal, built for a job a person repeats.
Software systems
The product itself: the parts that have to work together in production.
Software security
Hardening auth, APIs, payments, secrets, and the path that ships them.
CI/CD
The path from a commit to a release you can explain.
IoT hardware
A little. Enough to connect a device to the software around it.

Practice
What I will actually take on
A consultation is useful when the design is about to harden and the cost of being vague is real. These are the areas I will take on in a session.
CRM systems
Records, pipelines, and the work between teams. I design the platform a company actually runs on, and keep the edges clear.
Fintech systems
Wallets, ledgers, transfers, and reconciliation. I decide which system may change a balance, and what a person can see when it does.
AML
Monitoring, screening, and case handling. A score can rank a case; it should not be the only record of why money was held.
AI and machine learning
Scoring, assistants, and document work beside the ledger. I look at the data, the decision, and what happens when the model is wrong.
Software security
Threats at the edges that matter: auth, secrets, payments, APIs, and release paths. I harden what an attacker would actually try.
Enterprise
Several teams, one set of boundaries. Integration, identity, and a design another team can operate after the review is over.
Featured project
Reton
This is the company I'm building. Reton is a digital wallet. It holds the balances and a double-entry ledger. Interswitch is the payments company underneath: cards, transfers, and bill payments.
Wallet
Balances a person can see, and a timeline they can follow.
Ledger
Double-entry. Stricter than the status codes coming back from the rail.
Rail
Interswitch moves the money. It does not own the wallet.
Sessions
If you want my time
Remote, for clients in Nigeria and abroad. Pricing follows your location. Book and pay on WhatsApp.
Fit check
Free
Ten minutes to see whether the problem is a fit. Once per person.
