• ▸Led the server migration of an internal reconciliation application, ensuring zero-downtime transition, data integrity across all reconciliation records, and continuity of critical financial settlement processes.
• ▸Developed an institutional report generation module for PDF and Excel formats consumed by approximately 2,000 internal users, automating the production of financial statements, portfolio summaries, and reconciliation reports that previously required manual preparation.
• ▸Partnered with the Wealth Management team to develop and optimize backend services for client wealth product lifecycle management.
• ▸Provisioned and deployed internal service infrastructure through CI/CD pipelines (Jenkins, ArgoCD), reducing deployment cycles and improving release reliability.
• ▸Applied Design Thinking methodology to translate complex business requirements into scalable technical solutions, directly impacting client-facing product delivery.
• ▸Enforced enterprise-grade security and compliance standards across all services, ensuring adherence to financial regulatory frameworks.
• ▸Integrated continuous deployment and delivery pipelines for internal services across all development environments, standardizing release flows from dev to production.

Technical Backend Engineer for an AI-driven medical intelligence platform, architecting advanced RAG systems, multi-model orchestration, and HIPAA-compliant data infrastructure for healthcare providers.

• ▸Led backend architecture of an AI-driven medical platform using LangChain for multi-model orchestration across Claude, GPT-5, and Gemini, reducing average AI response latency by 35% through intelligent model routing and caching.
• ▸Designed and implemented a RAG-based conversational memory system with vector search (Pinecone), enabling persistent clinical chat context and reducing AI hallucination rate and improving diagnostic response accuracy.
• ▸Engineered a scalable Data Access Layer (DAL) with Prisma 7 and PostgreSQL, optimizing complex queries through advanced indexing and caching strategies, sustaining p99 < 500ms and p95 < 200ms under concurrent clinical workloads.
• ▸Implemented end-to-end encryption and HIPAA-compliant security protocols across all patient data flows, achieving no critical findings in our internal audits.
• ▸Integrated 3+ healthcare interoperability APIs (FHIR R4, SaludTools) enabling seamless data exchange across provider systems and reducing integration overhead by 50%.
• ▸Architected and deployed a multi-tenant authentication system using Clerk, reducing onboarding friction for new healthcare organizations by 70%.
• ▸Implemented API Gateway using AWS API Gateway and Lambda functions, reducing API response latency by 80% and reducing application bundle size.
