Remote Scala spark developer in India (UTC+6)
As a seasoned data scientist with a decade of experience, I specialize in building and scaling AI-driven solutions that deliver measurable business impact across the healthcare insurance, fintech, retail, eCommerce, IoT, and government sectors. My expertise spans—from advanced analytics and machine learning to deep learning and the latest advancements in generative AI and large language models. My journey began with a strong engineering foundation from IIT Varanasi and evolved into data science roles where I consistently transformed business challenges into scalable, production-ready solutions. At Tiger Analytics, I scaled a data science team from 1 to 25 members and led the delivery of 10+ AI/ML projects for a Fortune 50 healthcare insurer. Notably, I developed a predictive model that reduced direct mail costs by 40%, saving $2 million per quarter in senior health screening campaigns. I also created a fraud detection system for pharmacy claims that achieved 92% validation precision and a 60% hit rate on flagged claims, significantly reducing unnecessary audits and improving loss recovery. Additionally, I led the development of an NLP-driven call audit solution that expanded audit coverage from 5% to 100%, halved FTE requirements, and eliminated human bias. These solutions improved operational efficiency and empowered business stakeholders with actionable insights. For a global CPG client, I led the design and deployment of a hybrid recommendation engine that boosted product ranking by 5% and increased CTR by 10%, projecting $5 million in additional CLV. My work on smart pet devices integrated advanced ML pipelines for IoT sensor data, achieving F1 scores of 85% for activity detection and 95% for health monitoring. This innovation led to significant commercial success, with over 40,000 units sold of waste tracking device, $6 million in revenue, and an 85% daily active user rate—all within the first year of launch. Additionally, the predictive health framework developed is now patent-pending, with myself listed as a co-inventor. Previously at Algonox Technologies, I spearheaded AI integration for Dubai law enforcement, earning an Excellence in Technology Leadership award for halving investigative TAT and achieving over 80% F1 in legal classification. I also led the automation of mutual fund reconciliation for a leading fintech, scaling the solution to handle billions of transactions and reducing processing time from 15 days to just hours—a solution adopted by 15+ fund houses. My technical expertise spans Python, SQL, machine learning, deep learning, NLP, cloud platforms, and MLOps best practices. I am adept at building robust ETL pipelines, deploying models using Docker and MLflow, and integrating solutions seamlessly into business workflows via RESTful APIs. I emphasize reproducibility, operational excellence, and continuous improvement. Beyond technical delivery, I am passionate about mentoring, fostering high-performing teams, and bridging the gap between technical innovation and strategic business needs. Recent certifications in product management (Duke CE) and generative AI with large language models (Coursera) reflect my commitment to staying at the forefront of the field. After a recent career break focused on health, travel, and upskilling, I am energized and ready to contribute as a senior individual contributor or data science lead. I thrive in collaborative environments that value creativity, autonomy, and the transformative power of data. I am eager to join a team where I can take ownership of complex data challenges, build impactful products, and help shape ambitious data science roadmaps.
