What I'm looking for

I'm open to international remote backend engineering opportunities, with flexible working hours to collaborate across time zones.

At byx., I develop Python backend services and integrations for financial operations. I addressed database lock contention in a legacy Django/PostgreSQL application by implementing asynchronous batch processing; post-deployment monitoring showed no recurrence of import-related API latency spikes during business hours.

Previously, at NAVA - Technology for Business, I led the integration of a new banking provider, refactoring a legacy integration to support multiple providers and contributing to a multi-tenant banking microservice. At Azos, I enabled secure partner access to an internal simulation engine through GCP Apigee. I work with Python, Django, FastAPI, and REST APIs across financial services, insurance, and healthcare.
