What I'm looking for

I’m looking to lead and build scalable, maintainable products—owning architecture, backend logic, and API design—while collaborating cross-functionally in Agile teams. I want challenging systems with strong security, performance, and room to adopt new technologies.

I’m a Team Lead / Senior Developer with 13+ years of experience building scalable, maintainable products across MERN Stack and PHP development. I bring a strong analytical mindset and a focus on owning architecture, backend logic, and API design.

In my current role, I lead a team to design and deliver scalable web applications—driving system architecture, backend API design, and frontend integration. I run code reviews, provide technical planning and mentoring, collaborate with product managers and stakeholders, and ensure performance, scalability, and security through Agile delivery and sprint planning.

Across key projects, I’ve architected frontend governance and backend integrations for high-concurrency, real-time workflows—delivering secure payment processing (Stripe/Payarc), robust error handling, and stable data synchronization. I’ve also led Next.js architecture decisions, REST API contracts for web and mobile, and OpenAI/LLM integrations with prompt engineering and response guardrails.

I’m also “open to learning and adopting new technologies,” and I bring a reliable, dedicated delivery ownership mindset. I’m strongest when I can troubleshoot quickly, enforce best practices, and help teams ship secure, well-structured systems that scale.
