What I'm looking for

I’m looking for a role where I can build next-generation trading platforms end-to-end—backend, web, and mobile—using data-driven optimization, RESTful architectures, and AI/DeFi insights to deliver measurable improvements in performance and user experience.

I’m a Full Stack Software Engineer focused on delivering robust trading platforms with measurable impact. I’ve spent 9+ years building and optimizing backend services, web experiences, and mobile applications for trading users.

I specialize in Python, Flask, and PostgreSQL to improve performance and responsiveness, including a REST API approach that delivered a 30% improvement in application responsiveness. I design and optimize database structures to increase data retrieval speed, while monitoring user feedback to drive iterative enhancements.

On the frontend and mobile side, I build intuitive experiences with React/React Native and Kotlin. I collaborate closely across teams to integrate RESTful APIs and ensure seamless data flow between backend services and mobile apps.

Beyond standard fintech development, I’ve engineered automated trading algorithms and high-frequency trading bots using Python and machine learning for predictive analytics. I’ve also worked across DeFi and blockchain systems—building and auditing smart contracts, supporting secure infrastructure, and integrating AI-based risk management into trading platforms.
