Notes from the build.
Engineering deep dives, architecture decisions and what we learned shipping operations-heavy software.
Energy Is the Hidden Constraint on Tech in Emerging Markets
Unreliable power shapes budgets, product design and hosting choices long before it shows up in a pitch. How builders can design for interruption and treat energy as a real cost.
Open Weights or Hosted APIs: A Practical Comparison
Hosted APIs are fast to start and open weights give control, but the real costs sit elsewhere. A practical way to choose, test and keep your options open.
Why System > Person is the Only Way to Scale
Key-man risk is the silent killer of growing enterprises. Here is how we engineer systems that institutionalize knowledge and ensure zero operational disruption.
Migrations That Can Run Twice
A migration that dies halfway should be a rerun, not a lost weekend. How to write schema changes that are safe to repeat, resume and test.
Why Hospital Software Fails at the Front Desk
Hospital software often fails in the first ten minutes of a patient's visit. Why front desk workflows break, and what good registration, search and billing look like in practice.
Architecting the Treasury of the Future
How modern corporate treasuries are moving from spreadsheets to automated Cash Positioning.
Data Localisation and the Cost of Building Across Borders
Keeping data inside a border sounds simple until it reaches your database, backups, vendors and budget. A look at what localisation costs and how to design for it.
Idempotency Keys Are a Product Feature
A frozen screen and a second tap should never mean a double charge. Why idempotency keys belong in your product design, your documentation and your support tooling, not just your headers.
Telemedicine After the Hype
The urgency has faded and the grand claims with it. What remains is a set of tools that suit particular jobs, and a list of operational reasons why deployments stall.
Open Banking in Nigeria and the UK Compared
Both countries want customers to share their financial data safely, but they got there by different routes. A practical comparison of design, policy and what it means for builders.
The Rise of Tech-Enabled Consulting
Why traditional consulting firms are struggling to execute, and why the future belongs to systems architects who can both strategize and build.
Retries Without Regret: Backoff, Jitter and Budgets
Retries feel free until they turn a small fault into an outage. How to use backoff, jitter and retry budgets so your service helps a struggling dependency instead of burying it.
