IndiaWhat I'm looking for
I’m a Senior Backend Developer and Technical/Team Lead with 12+ years of experience building enterprise-grade backend systems using PHP, Laravel, and Python. I focus on scalable architectures, secure implementations, and high-availability solutions—especially in FinTech, ERP, and SaaS.
I’ve led technical delivery, code reviews, sprint planning, production deployments, and developer mentoring. At DexBytes Infotech Pvt. Ltd., I delivered the Chargezoom platform’s subscription billing, invoice management, reconciliation, and payment automation.
My work includes integrating 20+ payment gateways and accounting platforms, designing REST APIs and microservices for high-volume workloads, and improving API/database performance using Redis and SQL optimization (reducing API latency by ~40%). I also implement Docker, AWS, and CI/CD for reliable, low-downtime releases, with PCI DSS–aligned payment workflows and secure webhook processing.
