At Act Digital, I develop and maintain banking systems focused mainly on regulatory solutions. I optimized a bulk account data update system, increasing throughput 10x and reducing monitoring-screen response time by 95%.
That update also lowered support tickets by around 80%. I reduced the impact on dependent systems through batch publishing with RabbitMQ, indexing, and optimized pagination in PostgreSQL.
I improved asynchronous processing in a critical legacy account-blocking system, increasing throughput 10x and reducing costs by 85% through SQS batching, automatic retries, and resilience improvements in AWS Lambda. I also contributed to a federal payroll-deductible loan portability solution and resolved inconsistencies in PCM Open Finance reports.
Previously, at Ploomes, I built an automatic inventory integration from a client’s ERP into Ploomes CRM, eliminating manual user intervention. At Umbler, I developed systems to detect and block fake websites, reducing domain-blocking incidents caused by abuse reports by 100% and hosted phishing websites by 90%.
