At Exist Software Labs, Inc., I redesigned PostgreSQL schemas, queries, and indexes for a multi-tenant energy market platform, reducing reporting and bulk-processing latency by 50–90%. I also optimized high-frequency telemetry ingestion, cutting processing latency by 90% while ensuring data integrity.
I consolidated billing feeds from five legacy systems into an automated calculation and invoicing engine and engineered an HRIS loan approval workflow using RabbitMQ. Earlier, I developed Java/Spring APIs for participant registration and banking services, and increased automated test coverage across trade-finance modules from 20% to 80%.
