What I'm looking for

I am looking for a role that challenges my technical skills and offers opportunities for growth in a collaborative environment.

With over 14 years of experience as a product-oriented developer, I specialize in back-end development using Java, TypeScript, NodeJS, and AWS. My career has been marked by a commitment to finding simple solutions that effectively address customer problems while minimizing engineering complexity. I have successfully led significant projects that have driven substantial revenue growth and improved system reliability.

At Grab, I architected and led the development of critical systems that enabled the delivery of 50 million personalized messages daily and generated $7 million annually through innovative solutions. My role involved mitigating critical incidents and enhancing user engagement through AI-driven personalization. My experience at White Sand SRL further solidified my skills in building robust data pipelines and migrating complex systems to AWS, showcasing my ability to adapt and thrive in dynamic environments.
