• •Stakeholder Collaboration: Collaborate seamlessly across business lines, enterprise architecture, database administrators, infrastructure, Information Security, and third-party vendor teams to align technical delivery with strategic business goals.
• •SME & Agile Delivery: Act as the primary Subject Matter Expert (SME) for complex escalations, production incident triage (Sev-1/MIM), and root-cause analysis, while driving Agile/Scrum ceremonies to ensure predictable, high-quality, and timely delivery.

Technical & Domain Responsibilities

• •Java Microservices Architecture: Architect, build, and deploy production-grade, containerized Java microservices using Spring Boot, Spring Cloud, and RESTful/gRPC APIs, implementing distributed resilience patterns (Saga orchestrations, Circuit Breakers, Bulkheads, Outbox pattern).
• •Database Engineering & Query Performance: Design robust database models and persistence layers (Spring Data JPA, Hibernate, JDBC), execute query tuning, analyze execution plans (EXPLAIN PLAN), optimize indexing strategies (B-Tree, Bitmap, composite), and resolve connection pool (HikariCP) and row-level locking contentions in enterprise Oracle/SQL environments.
• •High-Availability Integration Design: Design and implement resilient, distributed integration solutions prioritizing active-active high availability (HA), fault tolerance, multi-region disaster recovery (DR), recoverability, and minimal business disruption.
• •Legacy-to-Cloud Modernization: Lead the architectural evolution and phased decomposition of legacy centralized middleware (TIBCO BusinessWorks, IBM MQ) into distributed, event-driven architectures utilizing Apache Kafka and cloud-native Java microservices.
• •Banking Domain Systems Integration: Apply deep expertise in banking and financial services to integration architecture, specifically in real-time fraud detection, payment processing rails (ISO 20022, SWIFT, Fedwire, ACH), clearing and settlement, and core enterprise banking ledgers.
• •Security, Audit & Regulatory Compliance: Ensure all integration services strictly comply with enterprise security baselines, audit controls, regulatory mandates (OCC, Fed, PRA, MAS), data protection rules (PII, PCI-DSS), Mutual TLS (mTLS) certificate management, and operational resilience standards.
• •High-Volume Real-Time Messaging: Oversee the architecture, throughput tuning, and management of real-time transaction flows, high-volume messaging pipelines, dead-letter queue (DLQ) automation, and sub-second SLA routing.
