Software Engineer with 4+ years building backend systems, and the last two spent building production AI: multi agent pipelines, LLM proxy layers routing between self hosted and cloud models, and MCP based automations. I like owning a feature end to end, from database schema to deployed UI, and I bring the same scrutiny to AI generated code as to my own: I read it, test it, and measure it before it reaches production. Looking for full time or long term contract work, backend or AI engineering, fully remote.
