Backend and platform engineer specializing in automation, distributed systems, and developer productivity, with a strong focus on building secure, compliant, and scalable software delivery platforms that enable teams to ship high-quality software faster.

My work centers on combining modern CI/CD, observability, and AI-assisted development workflows to improve software reliability, operational efficiency, and engineering velocity.

A strong advocate of shift-left software quality engineering, enabling defects to be detected as early as possible in the development lifecycle—during design, code review, and unit testing—where fixes are significantly less costly and disruptive. I work closely with engineering teams to embed testability and observability requirements directly into system design, influencing architecture and design templates to include mandatory sections addressing these concerns.

This includes initiatives such as improving production error handling and propagation, ensuring systems are observable, diagnosable, and resilient across distributed environments.

I also advocate for secure engineering practices and regulatory compliance by design, particularly around the protection of sensitive financial and customer data. During design and code reviews I promote safeguards such as encryption or masking when handling or logging personally identifiable information (PII), secure logging practices that prevent sensitive data leakage, and validation of access controls for internal APIs and services.

Recently I’ve been applying AI-driven development tools, AIOps practices, and advanced observability to automate failure detection, accelerate debugging, and improve system resilience.

Key areas of impact:

 • Architecting scalable CI/CD and deployment platforms

 • Building automated testing ecosystems for APIs, UI, and distributed systems

 • Implementing AI-assisted coding and automation workflows

 • Driving shift-left testing and design-for-testability practices

 • Designing observability pipelines for proactive operations (AIOps)

 • Applying statistical analysis and telemetry data to performance engineering

 • Promoting secure coding practices and regulatory compliance for sensitive financial data

 • Improving developer productivity through platform automation

I enjoy solving complex system challenges and enabling engineering teams to move faster while maintaining high reliability, security, and regulatory compliance.
