Long-form write-ups of production systems I have architected and shipped — the problems, the constraints that shaped the design, the engineering decisions, and the measurable outcomes.

EduLinkUp had courses but no path after them. I designed and led the rebuild into one Next.js platform that unifies structured learning, in-browser coding practice, open-source programs, internships and a community app store — now serving 2,700+ monthly active users across 100+ countries with 300+ new signups a month.

MBT Institute sold courses through ad-hoc channels and lost revenue to account sharing and manual payment handling. I built a production LMS — a Flutter learner app, a NestJS API and a Next.js admin console on Supabase — that locks each enrolment to a single active device, splits payments into hardware and software tracks, and delivers live classes and auto-published recordings. Shipped to Google Play as com.tensorik.mbt_lms.
