Wealthfy (SAAS product)

June 1, 2022 – June 1, 2026

Architected and deployed scalable Node.js REST APIs integrating MF Central CAS transactions from multiple brokers, supporting 50,000+ active users. Led the architectural migration of a wealth management reporting platform from a synchronous to a fully event-driven model using Node.js and Apache Kafka, reducing end-to-end processing latency by 60% and improving system scalability and fault tolerance. Designed and built a reusable JavaScript SDK for MF Central integration, reducing partner onboarding and integration effort by 40%. Optimized Node.js application performance using asynchronous processing, caching strategies, query tuning, and memory management techniques. Designed and optimized RESTful and event-driven APIs using Node.js and Express.js, ensuring low latency, high availability, and secure data exchange. Improved API response times and reduced server resource utilization through efficient event-loop handling and non-blocking I/O operations. Containerized backend services using Docker and deployed on AWS, enabling consistent environments, horizontal scalability, and faster release cycles. Drove the migration of a large-scale wealth management reporting system from synchronous services to an event-driven architecture using Node.js and Apache Kafka, improving throughput by 3x, reducing processing latency by 60%, and enabling horizontal scalability across distributed consumers. Designed and optimized complex SQL/NoSQL database queries, improving transaction processing speed and backend efficiency. Implemented database indexing, query optimization, and performance monitoring strategies, improving transaction processing efficiency for high-volume financial datasets. Implemented Apache Kafka for event-driven communication in Node.js applications, enabling high-throughput, fault-tolerant message processing and real-time data streaming between microservices. Designed and implemented MVC-based Node.js applications, ensuring clear separation of concerns and maintainable backend architecture. Applied SOLID principles and modular service design, improving code maintainability, testability, and scalability across distributed microservices. Owned full lifecycle delivery from design to production, enhancing API performance, scalability, and resilience in a FinTech SaaS ecosystem. Participated in architecture reviews and technical design discussions, contributing to scalable microservices and cloud-native solutions.

IDFC Bank Production Issue Management

June 1, 2022 – June 1, 2026

Led a 3-member backend support team managing high-priority banking production incidents, ensuring timely resolution and continuous availability of critical systems. Designed and implemented a standardized incident management process using Freshdesk, reducing average issue aging by 50% and improving SLA adherence. Owned end-to-end production issue lifecycle, from detection and triage to resolution, root cause analysis, and post-incident documentation. Implemented secure authentication and authorization using JWT, OAuth2, and RBAC, ensuring protected API access and enterprise-grade application security. Diagnosed and resolved production defects using Node.js, JavaScript, Redis, and SQL, optimizing backend performance and reducing repeat incidents. Integrated Elasticsearch-based log analysis, enabling faster troubleshooting, improved observability, and reduced mean-time-to-resolution (MTTR). Proactively monitored system health and stability, identifying performance bottlenecks early and preventing potential production outages. Improved scalability and operational efficiency by standardizing escalation workflows and knowledge sharing across production support and engineering teams.

Portfolio Summary (IDFC first bank)

June 1, 2022 – June 1, 2026

Led end-to-end development of a portfolio summary reporting system, delivering accurate financial insights for banking stakeholders and enterprise reporting needs. Managed and mentored a three-member engineering team, ensuring timely delivery, code quality, and adherence to enterprise development standards. Designed and implemented a scalable microservices-based architecture, enabling high-volume report generation and seamless future feature extensibility. Built backend services using Node.js and REST APIs, optimizing report processing performance and supporting increasing user and data loads. Collaborated closely with business and product stakeholders, gathering functional requirements and translating them into robust technical solutions. Authored detailed technical design documents and implementation plans, aligning system architecture with regulatory, performance, and business objectives. Ensured high system reliability and scalability by proactively addressing performance bottlenecks and supporting growing portfolio data volumes.
