SOFTWARE ARCHITECT | BACKEND ENGINEER | AGENTIC AI ENGINEER

Building Reliable Backends & Agentic Systems

I build enduring systems by leveraging software architecture to unify backend engineering and agentic AI. As an architect, I design for scalability and modularity; as a backend engineer, I prioritize reliability and security; as an agentic AI engineer, I embed self-improving learning. This integrated approach ensures every solution is future-ready—adapting to growth, new tech, or shifting business needs

What I Do

From designing resilient software architectures to implementing intelligent systems, I deliver technical solutions that drive business value and scale efficiently.

Software Architecture

I design robust and scalable software architectures, choosing between monolithic and distributed systems (microservices, event-driven) to meet your specific needs. Every system is modularized for maintainability and future growth.

Backend Engineering & DevOps

I build high-performance, scalable backend systems with a TDD mindset. I optimize database queries and algorithms for speed and efficiency. My ownership extends to production, using DevOps practices (CI/CD, Docker, Kubernetes) to ensure reliability and cost-effectiveness.

Agentic AI Integration

I'm growing my expertise in Agentic AI, moving from simple LLM API calls to building sophisticated agentic systems. This involves creating autonomous agents that can perceive their environment, make decisions, and take actions to achieve specific goals. I'm currently exploring architectures where agents collaborate, reason about complex tasks, and interact with external tools and data sources to solve real-world business problems.
