What I'm looking for

I seek a senior full-stack/backend role focused on cloud/serverless microservices, API and payment integrations, performance optimization, automation, and collaborative teams that value clean code and continuous improvement.

I am a software developer with eight years of experience building full-stack JavaScript applications using React, Next.js, Angular, Node.js, Firebase and AWS serverless technologies. I focus on delivering scalable web and mobile solutions with clean architecture and reliable APIs.

My core strengths are backend development and API integration, including REST APIs on Node.js, Firebase and AWS Lambda, as well as payment gateway integrations such as Stripe. I emphasize performance tuning across the stack—database indexing, memory-leak prevention, fast serialization, and optimized client rendering.

I also lead efforts in automation and quality assurance using WebDriverIO and CucumberJS, manage deployments and team code merges, and create technical documentation to accelerate onboarding. I have hands-on experience with microservices, API Gateway, S3, SNS/SQS and analytics instrumentation for production systems.

I have contributed to projects ranging from digital banking backends and admin portals to high-traffic news and telecom sites, and I hold a BS in Software Engineering. I bring a pragmatic, results-oriented approach and a commitment to mentoring teammates and improving delivery processes.
