From long-lived platforms to modern cloud services.
Anh Bui
Senior / Lead Software Engineer building reliable software for the real world.
More than 20 years of experience across .NET, Azure, fintech, payments, distributed systems, and legacy-to-cloud modernisation. I build business-critical services that stay clear and supportable under production pressure.

7
Live SaaS products
Browser software actively available to real users.
Production-first
Engineering mindset
Secure, observable, resilient, and supportable by design.
Engineering depth
Complex systems, made operationally clear.
I specialise in integration-heavy platforms where reliability, security, and traceability are part of the architecture. My approach is pragmatic: understand the failure modes, make state explicit, and build observability in from day one.
- Hosted checkout, tokenisation, 3-D Secure, and webhook-driven payment flows.
- Partner integrations across REST, SOAP, files, secure authentication, and asynchronous processing.
- Azure App Services, Functions, Queue Storage, SQL, Key Vault, and Application Insights.
- Incremental legacy-to-cloud modernisation without losing operational stability.
Products in production
I build and operate my own SaaS products.
Alongside professional engineering work, I run a growing collection of browser products used by real people. They turn engineering decisions into a complete product lifecycle: delivery, operation, feedback, and improvement.
- Product discovery, UX decisions, and focused solutions for everyday browser workflows.
- Chrome, Edge, and Chromium extensions with free and Pro capabilities.
- Licensing, device activation, release management, privacy-conscious design, and support.
- A short feedback loop between real usage, product decisions, and continuous improvement.
What I bring
Technical leadership grounded in delivery, production support, and steady improvement of the systems people rely on.
Fintech & Payments
Secure payment flows with clear state transitions, recoverability, and auditability.
Azure Cloud
Pragmatic cloud services designed for visibility, reliability, and day-to-day operation.
Integrations
Contract-aware connections across APIs, callbacks, queues, and file exchanges.
Reliability
Retries, idempotency, correlation IDs, monitoring, and incident-focused debugging.
Trusted by people I have worked with.
Recommendations from managers and colleagues highlight dependable delivery, adaptability, Microsoft-stack depth, communication, and a genuine interest in building better solutions.
