Building software that lasts.
I design secure, scalable Apple platform software that remains reliable long after its first release.
Over the past eight years I've architected banking SDKs, trading platforms, payment systems, and AI-powered products — software where performance, security, and long-term maintainability are not optional.
My work extends beyond writing code. Throughout my career I've been trusted to define software architecture, mentor engineers, review production code, interview candidates, and lead technical decisions across iOS, Android, and backend teams.
I enjoy solving engineering problems where architecture matters more than features.

BolourSecurity — Keychain, cryptography, biometrics, certificate pinning, JWT, and OAuth 2.1 behind safe-by-default Swift 6 APIs. Ten composable modules, zero third-party dependencies, published threat model and ADRs.
BolourArchitecture — Architectural primitives for modular Apple applications.
Alongside these: engineering case studies, long-form technical writing, and WWDC notes.
I believe software should become easier to maintain as it evolves.
I optimize for clarity over cleverness.
I value thoughtful architecture over unnecessary complexity.
I build systems intended to outlive the technologies used to create them.
Designing an authentication SDK for five banks What changes when your consumers are compliance departments — binary stability, API design as contract law, versioning without trust.
