Principal Studio • Arvind Kumar
Principal Full-Stack Engineer. 10 years taking systems from blank repo to production.
I am Arvind Kumar, a Vancouver-based Principal Full-Stack Engineer (+1 604-220-0601) operating an independent product and web engineering studio.
Over the past 10 years, I have engineered commercial websites, distributed platforms, and full-stack software. My foundation started with deep WordPress, PHP, and MySQL architectures for commercial operators and sports leagues, before advancing into modern TypeScript, React, Next.js, and end-to-end SaaS products.
Most recently, I built ReachRole (https://reachrole.app) from the ground up, engineering the complete product lifecycle: web application, ATS parsing pipelines, Razorpay payment passes, and companion Manifest V3 Chrome extension.
I work under a Studio of One model: direct senior engagement, zero junior delegation, and total accountability from day one. I partner with service business owners who need high-converting commercial sites and founders building production software.

Operating Boundaries
What I do not do.
No Agency Scope Games
I do not sell 8-tier generic retainer packages with hidden hourly caps or bloated management fees.
No AI Hype Without Utility
I do not pitch unmeasurable "AI transformations" for basic marketing websites. If AI is used, it solves a real workflow problem.
No Subcontracting
I do not accept projects only to quietly outsource the engineering to offshore third parties. You work directly with me.
Direct Access Required
I do not take freelance work through multiple layers of non-technical intermediaries. I work directly with the decision maker.
