I ship AI-native features and backend systems that scale in production — not demos that break at 100 users.
Currently engineering the aisentic AI plugin ecosystem (20,000+ active WordPress installations) and a unified AI backend at Arraytics. I cut AI integration costs by 35% and sped up feature delivery by 2x using harness engineering on legacy codebases.
Before this, I shipped high-value plugins and REST APIs at Incevio for zCart (1,000+ e-commerce platforms), adding $500 in value per sale. Earlier, I led teams at Data Sapience Lab building ML-powered apps and cut server costs by 34%.

| ICTBJ Conference | React, Node.js, MySQL | Official conference site for JKKNIU | Paper submission, registration, admin |
I'm targeting AI Engineering, Backend Engineering, and Full Stack roles where I can:
- Design LLM infrastructure that ships to real users at scale
- Own backend architecture decisions from database to API to observability
- Build full-stack products with AI as core architecture, not bolt-on features
I work best in teams that value end-to-end ownership, fast iteration, and production discipline over demo culture.
