Currently in South America and planning my move back to the US once a role is secured (whether in San Francisco or another city) to avoid relocating twice. Due to high interest in my work with recursive self-improving coding agents, I've shared an example repo at https://github.com/adam-s/agent-tuning https://github.com/adam-s/agent-tuning. I'm always open to discussing how I optimize agents for complex, repetitive workflows. I bring 13 years of full-stack UI development experience alongside deep expertise in browser automation and agents, which I've been engineering since 2018. This blend makes me particularly strong in QA automation engineering and complex frontend architecture. Notable projects include event ticket inventory management and a drag-and-drop CRM email builder for social marketing campaigns. As a consultant and full-time engineer, I’ve led 0-to-1 product development across streaming, real estate, edtech, marketing, and media. Having worked at companies ranging from a 130-person AI organization to a scrappy 7-person team, I thrive most in fast-paced, high-ownership environments. https://github.com/adam-s https://github.com/adam-s https://adamsohn.com https://adamsohn.com
