Varun S V — Software Engineer // Research Engineer

Kerala, India · Open to remote & hybrid

I build bridges between hardware and software — from converting PLC diagrams into XML to fine-tuning LLMs and automating the boring parts of engineering life. I mentor, ship, and occasionally over-engineer things for fun.

Persona

Equal parts curious tinkerer and methodical engineer. I prefer solid experiments, clear metrics, and code that survives real users. When not debugging an IoT stack I write little scripts to make life slightly less manual.

Current focus: LLM applications for industrial automation, robust test automation, and edge device reliability.
