Banking Infrastructure, Platform Infrastructure

◦ Led banking integrations with global fiat institutions supporting infrastructure responsible for $35B+ in monthly USDC transaction volume, primary responsibilities included collaborating with external banking partners to integrate APIs, diagnose outages, and resolve abnormal transaction states.

◦ Extended and maintained the transaction processing system handling fiat payment flows for USDC issuance and redemption, including payouts, push payments, settlement reconciliation, and returns across 5+ global payment rails.

◦ Integrated LaunchDarkly to design and implement a feature flag platform, including a sahred Java library, Terraform-based flag configuration, and GitHub Actions pipelines enabling automated management of 600+ feature flags across 28 production services with adoption continuing to grow.

◦ Led organization-wide migration from AWS Java SDK v1 to v2, building backwards-compatible platform modules for common AWS services such as SNS, SQS, and S3 to standardize infrastructure dependencies across backend services.

◦ Participated in on-call rotation for banking infrastructure supporting 10+ bank integrations, diagnosing and resolving production incidents including bank API outages, reconciliation mismatches, and stuck transaction lifecycles using Datadog monitoring and operational tooling.

Platform Infrastructure

◦ Built and maintained a Protobuf-based configuration service managing 1000+ blockchain configuration parameters across stablecoin services.

◦ Optimized configuration refresh and retrieval latency by up to 85%, significantly reducing propagation time for new blockchain parameters across stablecoin services.

◦ Maintained core platform libraries and shared infrastructure components used across backend services, managing dependency releases and compatibility across multiple production systems.

◦ Implemented observability using Datadog metrics and dashboards, supporting production reliability and incident response.

• Designed and developed RESTful APIs using Vert.X and Java that expanded the functionalities of the internal Chaos Engineering platform's administration portal.

• Identified shortcomings in existing micro services and implemented improvements to follow best practices for RESTful APIs.

• Supported the admin portal's development and maintainability by implementing standalone client classes that manage interactions with external micro services following the factory design pattern.

• Introduced and Implemented API request validations using javax annotations to expand validation coverage and provide informative responses to clients consuming the APIs.

• Supported product translations involving over 14 languages using C# and Javascript to support expansion into international markets and ensure regulatory compliance.

• Debugged defects in the complex codebase using VS debugger and Chrome Dev Tools to support user experience objectives.

• Developed automated tests using Selenium C# Web driver to prevent future changes from causing unexpected software errors.

• Identified and reported software defects using JIRA in an Agile/Kanban environment to ensure issues are known and can be prioritized.

• Developed a flexible and scalable CLI for collecting contextual utterances in S3 using Apache Spark and Python to improve Alexa's user interaction capabilities.

• Created a low-level design on the architecture, algorithm, and frameworks of the developed CLI to provide detailed documentation for internal teams.

• Wrote python unit tests using the unittest module to achieve 84% code coverage.

• Wrote user stories for each sprint to track and ensure project deliverables.
