Senior Software Engineer

StayNTouch Inc / QBurst Technologies Inc Bethesda, MD, USA Sep 2018 – Present

● Architected and delivered scalable backend services and RESTful APIs in Go and Python (Django/FastAPI), applying clean architecture principles to support rapid feature iteration across a SaaS hospitality platform.

● Decomposed a monolithic hospitality platform into independently deployable microservices in Go, enabling parallel team delivery and reducing deployment blast radius across a multi-tenant SaaS environment serving 300+ hotel properties.

● Implemented multi-tenant data isolation using PostgreSQL schema partitioning and row-level access controls, ensuring strict data boundaries and regulatory compliance across all tenant organizations.

● Designed and scaled a fault-tolerant payment orchestration platform integrating Adyen, Shift4, and FreedomPay, supporting 5,000+ daily transactions with zero-downtime gateway switching, 99.9% uptime.

● Built asynchronous event-driven pipelines using Redis-backed job queues to decouple guest check-in, payment processing, and notification services — improving fault isolation, retry reliability, and overall system throughput.

● Engineered an ML-powered guest check-in pipeline — trained passport detection models and implemented face detection, ID scanning, and liveness-based auto-capture, significantly reducing manual check-in friction and improving fraud resistance.

● Spearheaded native iOS and Android development for Rover, a hotel operations app; integrated RFID key card support (MIFARE Classic, ISO 15693) enabling seamless, hardware-backed room access control.
