Architected a BPMN 2.0-compliant drag-and-drop process constructor using TypeScript, React, Redux Toolkit, and Camunda Modeler, with server-side rendering via Next.js. Created interfaces for modeling customer onboarding, loan issuance, AML verification, and regulatory reporting with reusable React Hooks and real-time simulation. Developed role-specific dashboards and management platforms (React, TypeScript, Material-UI) with RESTful APIs (Node.js/Express) to support 20+ branch affiliates, auditors, and regulators, enabling live updates and collaboration via Socket.IO. Implemented robust access control and authentication (JWT with refresh token rotation, RBAC, Redis-based sessions, MFA with Twilio and SendGrid). Designed network bridge management interfaces using GraphQL, Apollo Server, microservices, and multi-database support (MongoDB, PostgreSQL) for real-time visualization of communications between engines and endpoints. Contributed to Agile processes, CI/CD pipelines, tests with Je

Spearheaded full-stack development of cross-platform banking applications serving 3M+ customers for a $1.7B revenue bank, architecting identical feature sets across React web app, React Native iOS, and Android platforms. Built Node.js back-end services with MongoDB for transaction processing, including P2P transfers, Twilio-based phone lookups, real-time SMS notifications, unique code generation, split payments via WebSockets, and international transfer integrations through local gateways. Developed advanced card management features with JWT-based security tokens, virtual cards, real-time currency displays via external APIs, and multi-currency support with PostgreSQL optimization. Engineered real-time account dashboards (React/Redux, Socket.io), offline mode (Redux Persist), and live chat via WebSocket. Collaborated in Agile sprints with CI/CD (Jenkins, Docker), comprehensive testing (Jest, Mocha, Enzyme), Swagger-documented APIs, and cross-platform data synchronization.

Rescued a failing commercial real estate startup by overhauling its web portal using Python, Django, Node.js, Express, and PostgreSQL. Fixed deep search using Elasticsearch, rebuilt the Excel import system with Python (openpyxl) and Node streams for varied formats, and improved UI responsiveness with React and modern CSS layout techniques. Built an internal analytics dashboard using Streamlit and automated reporting workflows to enable non-technical stakeholders to analyze property performance and market trends. Created subscription infrastructure from scratch with Django microservices and Node/Express, implementing JWT-based RBAC middleware (Passport.js) and tiered access APIs; integrated MongoDB for role management underpinning the revenue model. Implemented subscription billing with Stripe, secure webhook handlers, React checkout components, and recurring billing automation using Celery/cron/Node-cron; improved performance and reliability through Docker-based pipelines, zero-downtim
