01 / Interfaces
APIs that read like documentation
Predictable resources, honest status codes, errors a client can actually branch on. The contract is the product.
Software engineer / System design
Bismark Obuobi
I build the load-bearing half of software — the APIs, schemas and services that have to stay standing when nobody is watching them.
mostly Node & Postgres, occasionally Mongo when the shape fits

What I do
Three things, done properly
02 / Data
Schemas that survive the second year
Relational where relationships matter, document where they don't. Constraints in the database, not only in the application.
03 / Systems
Architecture with the trade-offs written down
Multi-tenancy, auth boundaries, payment flows. The parts that are expensive to change once real users depend on them.

Got something
worth building?
I'm interested in backend work, system architecture, and anything that forces me to grow as a software engineer.
