What I'm looking for

I seek roles where I can lead technical decisions, build scalable data and backend systems, mentor engineers, and optimize performance in cloud-native environments.

I am a senior software engineer with 4.5+ years building products for product-focused companies, focused on data pipelines, serverless architectures, and performance optimization. I design and implement backend systems, databases, and APIs using AWS, DuckDB, Databricks, and modern Python tooling, driving measurable improvements in execution speed and resource usage.

I lead technical decisions, mentor engineers, and build CI/CD and automation to support production systems. My work includes architecting RAG systems with OpenAI and vector stores, migrating heavy workloads to PySpark/Databricks, and delivering geospatial and energy dataset pipelines for UK-wide coverage.
