Principal AI Product Engineer @ buildwithpnj
I build production-grade AI applications, custom voice agents, and high-performance retrieval architectures that solve real-world problems. Operating under the brand buildwithpnj, I specialize in taking systems from initial design into robust, live customer production environments.
I am Prakash Nandan Jha, a software developer and AI engineer based in India. What started as writing simple command-line scripts to automate my own daily tasks quickly grew into a passion for building reliable software at scale. Today, I combine full-stack development with modern generative models, vector search, and agentic workflows to build software that operates autonomously and efficiently.
I focus on building software that solves concrete operations and growth problems. My work spans custom multilingual voice systems, semantic search engines, and real-time business dashboards. You can explore some of my active commercial work on the Projects page.
I believe in reliability, speed, and clean architecture. I write clean, grid-aligned code, build interfaces that put user legibility first, and ensure all systems run with low latency and secure parameters. For experimental ideas and pre-release tools, I maintain an active workspace on my R&D Labs page.
I build in the open because I believe the best way to understand systems is to share their blueprints. I document my design decisions, pipeline failures, and optimization logs in my Technical Journal. You can also watch live agent systems telemetry on the Mission Control dashboard.
Building a strong AI engineering brand as buildwithpnj while shipping revenue-generating verticals and production systems. We skip theoretical delay and focus on shipping working software.
