WRITING & CASE STUDIES

Notes from the build.

How I actually build these systems — architecture decisions, costs, failures, and results. No theory, no hype. If a post is marked "soon", it's being written between client work.

HOW THE PROJECTS WERE BUILT
01

AgroB2B Hub

LIVE · PRESS

How one person takes a B2B marketplace from empty repo to live platform with real companies and press coverage: scoping the frozen fruit trade, building marketplace mechanics (listings, matching, messaging), onboarding an industry that lives on the phone. Full write-up coming.

Blog-writing Telegram bots

LIVE

A content pipeline that lives entirely inside Telegram: research → structure → draft → format → publish, on schedule, with zero clicks. Architecture, prompt design, failure handling, and per-post running costs. Full write-up coming.

IN DEVELOPMENT

What founding a B2B marketplace taught me about shipping AI products

Lessons from AgroB2B Hub that transfer directly to 0→1 AI work: scope ruthlessly, launch embarrassingly early, talk to users daily.
