About me

Experience

Senior Software Engineer

GeoTech InfoservicesJul 2026 - Present

I own the architecture for automated customer onboarding and work on enterprise sign-in and our AI code review agent.

  • Designed and built two Spring Boot services to set up new customers. The workflow tracks each provisioning stage and supports rollback. I also built the AWS infrastructure with Terraform, using ECS, EventBridge, SQS and PrivateLink.
  • Worked with four domain teams to define onboarding requirements, wrote the specifications and implementation backlog, and presented the work to engineers and architects.
  • Added enterprise single sign-on with Microsoft Entra ID. I handled the backend APIs, Angular admin screens, gateway routes and identity-provider setup.
  • I'm leading work on Rust-based Language Server Protocol support so our AI review agent can navigate and understand code.

Software Engineer

GeoTech InfoservicesJun 2023 - Jun 2026

I helped build the platform's identity service from the start. Over time, I took on gateway fixes, document storage and tools that other teams used in their services.

  • Built authentication, invitations, login flows and profile management with Spring Security and Auth0, using OAuth 2.0 and OpenID Connect. Later, I led the identity service's move from MongoDB to PostgreSQL with Liquibase.
  • Fixed premature logouts and concurrent token-refresh bugs in the API gateway. I added rules and automated checks for routes, plus shared libraries for OpenFGA authorization, JWT propagation and token caching.
  • Built document storage with per-tenant quotas and upload limits, plus tagging, retention and search. I also built an engine that uses configuration to map requests and responses for external data providers.
  • Helped build compliance audit logging with immutable object storage and OCSF-aligned schemas. We used Athena to query the logs and added paginated exports.
  • Proposed and built an AI code review agent that the company adopted as a pull-request quality gate.
  • Led small teams building tools for tender analysis with retrieval-augmented generation, AWS Bedrock and Textract.

Trainee Software Engineer

GeoTech InfoservicesJun 2022 - May 2023

I worked on tenant security and automated the setup and removal of tenants in an insurance system.

  • Added IP allowlisting with CIDR ranges, account lockout and session revocation. I also checked the system's OpenID Connect compliance.
  • Designed and built onboarding and offboarding workers that handled tenant data and tracked each operation's status.

Intern

GeoTech InfoservicesDec 2021 - May 2022
