● Replaced manual outreach by CX agents with a backend AWS Kinesis automation pipeline that

processes vendor data, creates CRM profiles, and sends text messages. Freed up CX time and

increased user outreach scale. Decreasing time spent by agents from 2 hours down to 2 minutes.

● Migrated bank transaction ingestion from Plaid to Akoya, including Chase. Updated web services,

queue handlers, and background jobs to call Akoya APIs, store normalized data, and support front-end

connection flows—cost savings by 30%.

● Designed a queue-based processing system to classify transactions from multiple sources and persist

enriched results in DynamoDB. Integrated ML gRPC services to replace legacy string-matching logic.

Reduced classification errors by 25% and improved transaction processing throughput by 40%,

enabling downstream services to access normalized data via new API endpoints.

● Partnered with ML teams to consume earnings eligibility predictions from Kafka. Created scheduled

jobs to ingest and persist ML results, then refactored legacy earnings logic to leverage ML

insights—leading to improved grant accuracy by 10% of users.

● Solved production outages by designing a per-bank fixed-window rate limiter with async fallback

publishing. Ensured reliable third-party communication and prevented API throttling reducing error

rates by 40%.

● Designed and implemented a role-based access control system for API permissions using Go,

enabling fine-grained authorization and secure user management.

● Add APIs for bulk items for a Ruby-based synchronization service (etcd), ensuring seamless user

management across legacy and modern systems during product migration.

● Developed service account management features to facilitate secure machine-to-machine

authentication, improving automation and system interoperability.

● Built and maintained B2B e-commerce APIs with Ruby on Rails, decreasing customer support tickets

by 30% thanks to automation of shipping and invoicing.

improvement in Lighthouse accessibility score and a 15% reduction in Cumulative Layout Shift (CLS),

contributing to better SEO and user experience.

● Maintained and contributed to public data sampling APIs with Golang and gRPC (microservice)

enabling 2.5x user growth on research platforms.

● Led redesign of internal survey tool UI, cutting user-reported errors by 10% and improving satisfaction

scores.

● Delivered a new React-based B2B survey-building platform that reduced project setup times by 20%.

● Rewrote core analytical fetch tools, which reduced computation costs by $25,000 annually and

improved report generation speed from minutes to seconds.
