Serve as lead architect for EngageX, a next-generation student engagement SaaS platform — owning technical vision, system design, and architecture standards for a team of 20+ engineers. Produced end-to-end HLD/LLD documentation (context diagrams, component diagrams, sequence flows, data models) using draw.io, providing a shared blueprint for cross-functional teams.

• Designed scalable, API-first microservices using Spring IO ecosystem (Core, Data, Security, Web, Messaging, Cloud) and Spring Boot, delivering high-availability services on AWS.
• Drove modernization from legacy AngularJS/Node.js monolith to React micro-frontend + microservices (Strangler-Fig pattern), improving scalability and enabling independent deployments.
• Established security-by-design practices including Spring Security (OAuth2/JWT), IAM role-based access control, and SonarQube SAST integration — ensuring OWASP compliance across all microservices.
• Implemented SRE framework covering service-level objectives (SLOs), error budget tracking, distributed tracing, and alerting dashboards — improving MTTR by ~35% and maintaining 99.9% uptime and rate Grafana dashboards.
• Established TDD standards, code review governance, and secure coding guidelines — reducing production defects and improving release confidence across the 20+ engineer team.
• Introduced load testing pipelines using JMeter to simulate peak traffic, identify application bottlenecks (slow queries, thread contention, memory leaks), and validate system behavior under stress — improving p99 response times by ~30%.
• Complemented application-layer testing with AWS network-layer performance analysis using CloudWatch metrics, VPC Flow Logs, and X-Ray tracing to pinpoint latency hotspots across ECS/Fargate services.
• Initiated POC and production implementation of Global Search using Microsoft ML models integrated with Spring AI and MCP, enabling intelligent AI-to-system communication.

(2023-07 - 2024-06)

Led solution architecture and technical strategy for insurance-domain digital products, managing a cross-functional team of 40 engineers across multiple concurrent delivery workstreams.

• Designed high-level and low-level architecture (HLD/LLD) for insurance-domain digital products using Microservices, Event-Driven (Kafka/Dapr sidecar pattern), SOA, and MVC patterns on GCP (GKE, Pub/Sub, Cloud SQL). Led structured tradeoff analysis across synchronous vs. asynchronous communication, eventual vs. strong consistency, and monolith-first vs. distributed-first approaches — documenting decisions using draw.io and Confluence for stakeholder alignment.
• Enforced security architecture standards including API gateway-level authentication, secrets management (Vault), and network security policies (VPC, firewall rules) across all insurance-domain services.
• Established SRE monitoring using cloud-native observability tools — log aggregation, distributed tracing, and uptime alerting — ensuring SLA compliance for insurance-critical workloads.
• Collaborated with presales, PMO, and senior client stakeholders to author RFP responses, SOW specifications, and engineering roadmaps ensuring business-technology alignment.
• Established delivery governance covering release management, quality assurance, and sprint planning across distributed teams.
