I'm a seasoned Full Stack Developer with 12+ years of experience, specializing in building high-performance, AI-integrated web applications using Python (FastAPI, Django, Flask) and JavaScript/TypeScript (React.js, Next.js). I bring 5+ years of full-stack experience across healthcare and finance, with backend expertise in Python microservices, REST/gRPC APIs, PostgreSQL, and ORM frameworks like SQLAlchemy and Django ORM. I also work with AI tools such as Cursor, Visual Studio Copilot, and LLM APIs including OpenAI and Mistral to accelerate intelligent feature development. With a strong foundation in microservices architecture, event-driven systems, and CI/CD automation, I build robust and secure applications aligned with compliance standards like HIPAA, FHIR, PCI DSS, and SOC 2. I bring hands-on experience in developing machine learning pipelines, serving ML models in production, and implementing MLOps workflows using Python-based tools like MLflow, Airflow, and Kubeflow. Beyond coding, I thrive in collaborative, agile environments—mentoring cross-functional teams, driving DevOps culture, and continuously improving product reliability, performance, and user experience. I’m passionate about leveraging Python and modern cloud-native technologies to deliver impactful, intelligent digital solutions for mission-critical industries. I'm excited to continue delivering scalable, secure, and AI-powered software that helps healthcare and financial institutions operate more efficiently and safely.
