What I'm looking for

I am looking for a role that fosters innovation and collaboration, where I can apply my skills in machine learning and software development to drive impactful solutions.

I am a dedicated Software Engineer and Data Scientist with hands-on experience in building fraud detection systems, real-time data pipelines, and LLM-powered automations. My journey in technology has equipped me with a strong foundation in backend engineering and applied machine learning, allowing me to develop innovative solutions that enhance operational efficiency.

At Cloudwalk (Infinitepay), I successfully built and deployed a stolen device detection model that significantly reduced user fund thefts and chargebacks. My work on an internal Slack LLM bot automated manual risk workflows, saving the monitoring team over 40 hours weekly. I am passionate about leveraging technology to solve complex problems and improve processes, as evidenced by my development of an LLM-powered alert classification system that triaged daily fraud alerts.

Throughout my career, I have embraced opportunities to mentor junior developers and lead critical production bug resolutions, ensuring stability and reliability in core business operations. My experience spans full-stack development, machine learning, and data analysis, making me a versatile asset in any tech-driven environment.
