What I'm looking for

I’m looking to lead backend and cloud-native system design for real-time, high-scale products—where I can combine event-driven microservices with AI/LLM integrations and build reliable, secure architectures with strong team collaboration.

I’m a Senior Software Engineer with 10+ years of experience building distributed systems, cloud-native platforms, and backend microservices across fintech and consulting. I focus on designing scalable systems that hold up in real production conditions.

I’ve delivered end-to-end solutions for enterprise clients, building high-performance backend services with Go and Python and implementing event-driven architectures with Kafka and Flink. In high-scale environments, I’ve supported production incident resolution and reliability improvements to maintain SLA compliance.

I’m also hands-on with AI/LLM integrations, including RAG pipelines and model orchestration, using OpenAI APIs and Hugging Face. I’ve built model control systems that route between multiple LLMs based on latency, cost, and accuracy, alongside secure, privacy-compliant data architectures aligned with GDPR/CCPA.

Across AWS and Azure, I architect containerized microservices and cloud-native deployments using Kubernetes and Terraform, then connect them with ETL and data workflows using Airflow and Spark. I enjoy mentoring teams, enforcing engineering best practices, and translating stakeholder needs into scalable technical designs.
