– As the Solution Architect for the Identity Core initiative, I design and deliver secure, scalable authentication and authorization systems built on Auth0 and custom Java microservices. My mission is to ensure frictionless user experiences while maintaining enterprise-grade security and compliance. – Architected and integrated Auth0 as the centralized identity and access management (IAM) solution across multiple SaaS platforms. – Designed and implemented authentication and authorization workflows supporting username/password, social logins, multi-factor authentication (MFA), and single sign-on (SSO) with external identity providers (Azure AD, Google, etc.). – Developed and maintained custom Java Spring Boot microservices for token management, user provisioning, and permissions synchronization. – Collaborated with product and security teams to define zero-trust policies, audit trails, and GDPR-compliant data handling. – Deployed and monitored production workloads on AWS (EC2, RDS, S3, CloudWatch) using Datadog for observability and performance tracking. – Contributed to company-wide architecture decisions, CI/CD pipelines, and microservice best practices to ensure resilience and scalability. – Reduced authentication latency by 35% and improved login success rates across all integrated apps. – Strengthened security posture by enforcing MFA adoption and centralized identity governance.

– Worked on the eCommerce FinIntegration (eCFI) team, managing financial transaction events and audit reporting pipelines for Amazon's global marketplace. – Developed and optimized SAFE (Simplified Accounting Folio Engine), ensuring 0 % data loss and full audit traceability. – Built Lambda functions to automate partner onboarding and reconciliation processes. – Improved service performance by profiling & refactoring, reducing latency by 30 %. – Delivered secure, high-volume data pipelines using AWS S3, DynamoDB, and Kinesis.

– Led backend architecture for the Program Manager Platform, a cross-division solution integrating multiple transport-system modules through a unified, extensible GUI. – Architected a scalable microservices ecosystem enabling integration of 10 + modular apps. – Designed cloud-ready APIs using Spring Cloud Gateway, Consul, and ELK. – Improved system reliability and observability via profiling and monitoring dashboards. – Provided technical leadership and architectural reviews across multiple R&D teams.

– Contributed to the development of compliance and risk management platforms for financial institutions. – Focused on microservices and workflow automation aligned with AML regulations. – Enhanced platform scalability and data processing performance. – Collaborated with cross-border teams to ensure regulatory compliance and integration quality.

– Developed REST microservices and an API Gateway for the R&D Data Pole team, supporting energy consumption analytics. – Built APIs handling real-time data from thousands of smart meters. – Created a reporting dashboard for business intelligence and performance analysis. – Integrated CI/CD pipelines and automated testing (JUnit, SonarQube).

– Enhanced the Palmyra Framework and API Gateway, supporting core banking and insurance solutions. – Improved framework performance and reliability for tier-1 financial clients. – Implemented unit tests and profiling tools to reduce bug density by 20 %. – Collaborated with international teams on custom module development.

– Developed a testing framework and web app for automating performance and security tests for HR products.
