What I'm looking for

I seek roles where I can build scalable backend systems, optimize performance and automation, mentor teams, and drive measurable business impact in collaborative, product-focused environments.

I am a Senior Backend Engineer with 6+ years delivering efficient, high-impact solutions that improve customer experience, team productivity, and business outcomes. I design scalable APIs and systems using Node.js/Typescript, NestJS, microservices, and data stores like Postgres, MongoDB, Elasticsearch, and Redis.

I have led performance and automation initiatives that cut search response times by 30% and reduced voucher distribution from hours to minutes, while building omni-channel integrations and batch processing pipelines that multiplied commercial productivity.

As a product-minded engineer and former trainer, I prioritize pragmatic system design, effective collaboration, and mentoring to drive reliable releases and measurable business value.
