Technical Lead for enterprise-grade third-party API integration solutions, building automation tools to improve governance and operational efficiency across internal platforms. Responsible for full-cycle delivery: architecture, development, testing standards, and mentorship.

• Automated the access-renewal process to cloud platforms holding legal & financial documentation, eliminating human intervention and freeing 3 IAM resources for higher-priority work.
• Led migration of critical document-management services from Spring MVC to reactive WebFlux, achieving a 455× throughput improvement — async jobs averaging 3h 30m now complete in ~45 minutes.
• Introduced a batch service to purge inactive channels in the enterprise communications platform, measurably reducing operational cost.
• Documented and standardized the API testing process; built a centralized Postman workspace used by both engineers and authorized non-technical stakeholders for validation of all team-owned features.
• Delivered full test coverage on new customer-facing components; mentored engineers on Spring, security best practices, and platform-specific tooling.

• Optimized Oracle PL/SQL databases: queries, stored procedures, and indexing strategies; configured Azure Cloud Services for microservices integration (Azure Functions, App Services, Blob Storage).
• Introduced automated load-testing data-generation and input-simulation suite, cutting performance-test resolution time by 73% (15 → 4 days).
• Documented architectural design and undocumented platform functionality for R&D teams, creating a centralized knowledge base that unblocked feature enablement and validation.
• Became primary onboarding resource for new team members (junior and senior); delivered full architecture and stack transfers, reducing ramp-up time significantly.
