Senior .NET developer. Backend and Azure engineer.
I build C# APIs, Azure integrations and SQL Server systems. With 7+ years in software engineering, I turn complex requirements into services that are easier to maintain and support.

02 / EngineeringHow I design systems
From request
to reliable service.
Explore the layers of a typical .NET and Azure backend. Select a component to see its role in security, data integrity and reliable delivery.
Web and mobile clients that initiate requests and render the responses people actually use.
A single managed entry point — routing, versioning, rate limiting, and policy enforcement before traffic reaches a service.
Identity, tokens and scopes — establishing who is calling and exactly what they're allowed to do.
The service layer — clear contracts, request validation, and orchestration of the work behind each endpoint.
Focused services with clear ownership, talking over well-defined boundaries so each part can evolve on its own.
Relational persistence — schema design, integrity constraints, transactions, and queries tuned to the access patterns.
Cloud hosting, networking and managed services that keep the system available and operable.
Reproducible builds, automated checks and safe, traceable deployments — shipping change without surprises.
Structured logs, metrics and traces, so when something fails it can actually be investigated.

03 / How I approach workBeyond the tools
Think deeper.
Build clearer.
01 / Understand
Find the actual problem.
Understand the users, constraints and failure cases before choosing the tools or architecture.
02 / Engineer
Make the core dependable.
Use clear API contracts, focused boundaries and validation. Make services secure, testable and easy to investigate when something fails.
03 / Improve
Build, review and refine.
Test assumptions, review the result and improve it. Independent projects help me connect backend decisions to the experience people use.

7+
Years in software engineering
7+ years in software engineering, from Infosys training to backend and Azure projects for clients including Bupa and the World Bank Group.
From the unseen layer
to the whole product.
My professional work focuses on .NET APIs, Azure integrations and data systems. Alongside it, I build independent products to develop the frontend and product skills that connect the whole experience.
