Led architecture and end-to-end implementation of a multi-service health platform, owning NestJS EMR APIs, Django integrator, React/Next.js patient portal, Saleor apps, and Phoenix dashboards. Built a multi-tenant EMR service and internal dashboards (NestJS, TypeORM, MySQL) handling prescriptions, telemedicine links, doctor reviews, and chat threads linked to patient profiles. Created a Django integrator service connecting Saleor, EMR, payment gateway, referrals, identity verification, and subscription/auto-order logic via REST APIs, webhooks, and Celery tasks. Developed a patient portal and Saleor checkout apps surfacing EMR data, questionnaires, orders, labs, and chat threads across dashboards. Implemented cross-channel communications with Omnisend, Twilio, and EMR–portal chat notifications, with asynchronous processing and translation. Integrated Lifefile APIs, S3 document delivery, and robust HTTP client abstractions with retries and observability. Introduced experimentation and

Architected and delivered an end-to-end GenAI platform for automated gene pathway analysis using Python, Django, React, and GPT-4, enabling efficient extraction of pathway information from scientific documents. Designed specialized computer vision and OCR pipelines (MMOCR, SAM, Google OCR, Detectron, Siamese networks) to reliably detect gene pathway images and entities. Built LLM-powered RAG pipelines integrated with external gene/protein databases to provide citation-backed answers. Orchestrated multi-LLM workflows combining GPT-4, Claude 3, and Gemini with advanced prompt engineering to interpret gene relationships and multimodal pathway content. Implemented verification and quality-control framework (cross-model voting, validators, consistency checks) reducing errors and increasing trust. Developed full-stack Django REST Framework backend and React frontend for document uploading, detection method selection, results review, and analysis management. Engineered scalable backend servic

Designed and developed full-stack web apps for internal banking operations (customer onboarding, loan processing, risk dashboards) using Python, Django/Django REST Framework, and React. Built secure REST APIs backed by PostgreSQL/SQL Server and implemented authentication, input validation, and audit logging. Developed responsive frontends with reusable components and data visualizations for staff and risk teams. Implemented business logic in Django services and database layers to optimize high-volume transactions. Integrated internal/external services (KYC/AML checks, credit bureaus, notifications) via REST/JSON, automating fraud checks, credit approvals, and customer servicing. Collaborated with data/ML teams to expose model outputs (fraud scores, risk, customer segments) via APIs and UI components for real-time decisioning. Applied unit/integration testing, CI/CD, and Agile methodologies to ensure reliability and maintainability.
