What I'm looking for

I’m looking for a remote-friendly team to build secure, high-traffic REST APIs and FinTech payment microservices—while mentoring engineers and continuously optimizing databases, webhooks, and system design for reliability.

I’m a result-driven Senior Backend Engineer with 8+ years of experience designing, constructing, and scaling enterprise-grade cloud applications, transactional engines, and robust API frameworks.

I architect secure FinTech payment infrastructures and engineer high-performance microservices—turning ambiguous requirements into clean, modular code while reducing database bottlenecks through query and schema optimization.

In my recent role, I’m scaling Laravel business web infrastructures by building decoupled REST APIs, optimizing complex backend operations, and standardizing codebase guidelines in distributed agile teams.

Previously, I built enterprise SaaS platforms with Laravel and CodeIgniter, integrated end-to-end payments with Stripe and Razorpay (including resilient webhook processing), and contributed to open-source Django and JavaScript packages, alongside production Flutter apps.
