Laravel Backend Engineer • PHP Architect • Fintech & APIs Specialist
8+ Years of Engineering Elegant & Resilient Architectures
I am an accomplished Backend Engineer with 8+ years of professional software engineering experience, specializing over the last 3 years in the Laravel and modern PHP ecosystem. My career spans high-scale, security-first fintech solutions and enterprise-grade government banking applications.
Throughout my journey, I have specialized in building transaction-heavy architectures, integrating multi-layered payment gateways, managing complex KYC verification pipelines, setting up robust role-based access control (RBAC), and optimizing relational databases (MySQL and DB2) under heavy query loads.
As a modern, forward-thinking developer, I actively design and accelerate my engineering workflows utilizing cutting-edge **AI-assisted development ecosystems** (ChatGPT, Claude, Gemini, DeepSeek). By employing structured prompt-engineering and agentic coding workflows, I achieve rapid prototyping, immediate bug discovery, and fast-tracked architectural exploration, keeping delivery cycles extremely fast and efficient.
