About Me

I help companies architect and scale enterprise SaaS platforms that remain stable as they grow. With over 5 years of experience building systems with Laravel, React, TypeScript, and AWS, I focus on delivering high-performance infrastructure that handles real production scale.

My work includes contributions to platforms used in enterprise environments by organizations such as Samsung, Rivian, Philips, and Kering, supporting systems that manage 10M+ records with 99.9% uptime across complex regulatory and operational workflows.

I focus on building systems that remain maintainable long-term by applying SOLID architecture, automated testing, and efficient database design, helping teams consistently achieve 95%+ on-time delivery.

Beyond building features, I reduce operational friction by implementing automated data pipelines and resilient third-party API integrations, cutting manual overhead by up to 60% while keeping systems scalable and reliable.

I don't just build features - I design systems that stay reliable as your product scales.
