What I'm looking for

I'm looking to build scalable, reliable backend systems, make sound architectural decisions, and solve data-intensive production challenges.

At Rolique | Lendio, I build Node.js and TypeScript services for a high-load U.S. lending and banking platform, including core banking integrations with Finicity, Ocrolus, and Plaid.

I improve data-intensive workflows through MySQL and Knex optimization, reducing query execution from over two seconds to about 0.4 seconds. I also resolved a reporting memory leak, cutting memory use from about 10GB to 10MB and report generation from 10 minutes to two.

Previously at SoftServe | Cisco, I developed secure enterprise backend services, endpoint-level RBAC, and reusable audit logging. Across my career, I’ve worked with PHP, JavaScript, Angular, GraphQL, Elasticsearch, payment systems, and production applications.
