Led a cross-functional team of 6+ engineers building AI-powered platforms across web (React/TypeScript) and mobile (React Native). Architected features using OpenAI GPT-4 and LangChain, including conversational assistants and natural-language interfaces. Built RAG systems with vector embeddings for real-time financial document analysis to support underwriting decisions and compliance reporting while maintaining PCI DSS and SOX standards. Designed and launched cross-platform React Native mobile banking apps with biometric authentication, real-time transaction processing, and AI-driven insights supporting 100K+ active users with 99.9% uptime. Drove Python backend microservices development with Node.js and GraphQL APIs, real-time event processing, and ML pipelines for fraud detection and credit risk. Implemented technical leadership practices (architecture reviews, code standards, CI/CD, mentorship) reducing deployment time by 60%. Established test-first engineering with Jest and Supertes

Led a cross-functional team of 6+ engineers building AI-powered platforms across React/TypeScript web and React Native mobile. Architected GPT-4/LangChain features including conversational assistants and document processing, and built RAG systems with vector embeddings for real-time financial document analysis and automated underwriting/compliance reporting while maintaining PCI DSS and SOX standards. Designed and launched cross-platform mobile banking experiences with biometric authentication and real-time transaction processing, supporting 100K+ active users with 99.9% uptime. Drove Python backend work for core microservices, implementing Node.js and GraphQL APIs and real-time event processing for fraud detection and credit risk assessment. Established test-first engineering with Jest/Supertest and NestJS testing utilities to reach 85%+ coverage and catch 90%+ of regressions before production, while reducing deployment time by 60% through architecture reviews, code standards, and CI/

Led end-to-end delivery of a unified SaaS application spanning frontend architecture and backend services for two consumer lending products used by 10K+ monthly active customers. Built and maintained a shared UI platform with 150+ reusable components across 6+ product areas, accelerating development velocity by 30% with AI coding assistants for refactoring and test creation. Improved user experience using React and Next.js, raising SEO rankings from page 3 to page 1 and reducing time-to-interactive by 40%. Designed transactional APIs sustaining 50K+ requests per minute with 95ms P99 latency. Introduced a GraphQL aggregation layer across 6 backend services, reducing redundant payload transfer by 50% across 10K+ daily queries. Standardized CI/CD pipelines (8 total), cutting deployment cycles from 45 minutes to 15 minutes and reducing environment-related issues by 50%. Provided technical guidance and mentorship to 8 engineers, improving onboarding by 20% while maintaining high code qualit
