Sep 2025 - Jun 2026 • Bogota, D.C., Colombia (Hybrid / Remote)
- Engineered an enterprise real-time anti-fraud engine from scratch in Golang utilizing the Strategy Pattern to detect cashier collusion and rolling-window velocity anomalies, delivering sub-50ms synchronous endpoints into POS checkout with cross-timezone normalization.
- Architected and deployed mission-critical microservices in Golang adopting Clean/Hexagonal Architecture and Go concurrency primitives (Goroutines, channels, worker pools) on DynamoDB and Redis, enabling non-blocking execution across high-volume transactional flows.
- Centralized the core authentication platform into a unified OTP/TOTP microservice, enforcing strict rate limiting, transactional failover to relational storage, multi-channel billing calculation (SMS, WhatsApp, Email), and secure legal document attachments.
- Decoupled analytical workloads from operational OLTP databases by integrating native gosnowflake drivers into Go microservices, aggregating millions of marketing interactions (sends, opens, clicks, ROI) into real-time merchant dashboards.
- Spearheaded DevSecOps compliance and CVE remediation across 10+ core repositories under Vanta / SOC 2 standards, hardening Alpine production containers with dumb-init, migrating to modular AWS SDK v3, and engineering Rust contactability pipelines with zero-downtime Unleash feature flags.
