Oğuzhan Berke Efe — Full‑Stack & Mobile Engineer
I turn ideas into living digital systems.
From mobile experiences to distributed backends, I design fast, observable and human-centred products.

Code is not invisible infrastructure; it is the rhythm of the product.

How I work
Listen
I read the problem, people and system signals together.
Model
I make boundaries, data flow and real risks visible.
Build
I build the product in small, verifiable slices.
Observe
I treat post-release signals as part of the design.
Architecture by context
There is no universal architecture recipe. Scale, team, domain complexity and operational load determine the right boundary.
Clean Architecture
For long-lived, multi-team products where domain rules must evolve independently from UI and infrastructure.
MVC / Modular Monolith
For smaller teams, clear domains and fast delivery; it keeps operations lean while preserving module boundaries.
Microservices
When independent scaling, release cadences and strong domain ownership justify the operational cost.
Event-driven
When integration volume, latency tolerance and auditable workflows matter more than synchronous coupling.
