Over mij
Software engineer with 5+ years of experience building backend systems in Python (Django, DRF, FastAPI, Flask) and PostgreSQL/PostGIS. I've worked on fintech platforms handling 1M+ daily transactions, cutting processing time by 40% through better queries and Redis caching. Experience with Kafka, Celery, Docker, and KYC/KYB integrations. I focus on clean, reliable code delivered on time, not just code that works once. Recently built an AML screening API with fuzzy name matching against sanctions and watchlist data. Portfolio: https://md-arman-hossain-portfolio.netlify.app
