Live data and PMF logs from AI products built and operated firsthand — WICHI (GEO SaaS), Make Me Unicorn (OSS), Self-Tuning Loop, and Minbook itself, with decisions recorded chronologically.
Less code, more decision: 9-Bucket framework design, multi-engine architecture transitions, integrating security, observability, and payments — the operational stages tutorials skip.
Written for solo builders shipping their own SaaS or OSS, and PMs and founders wanting to see solo-operation limits and possibilities together. Live numbers and one-line decision notes share the same page.
Three months after first opening Claude Code on Lunar New Year, I started by building everything in parallel, then nobody came, then I returned to my own pain point - a news-collection workflow. The same sequence shows up everywhere at meetups.
Operational review of WICHI's backend on Railway and Supabase, covering real-world incidents like connection pooling and migration conflicts, plus criteria for infrastructure migration.
Analysis of the design philosophy and hierarchical dependencies of the four GEO Score layers (Inclusion, Prominence, Quality, Stability), and their implications for decision-making.

Documenting the psychological mechanisms and viral loop strategies behind three sharing elements designed for MMU's PLG growth: score cards, badges, and custom checklist links.
Solving the false-pass problem in MMU's checklist by designing a condition marker system with 17 feature flags and improving score accuracy through 48 regression tests.
Strategic analysis of three opportunity factors in the AI search (GEO) market and why WICHI chose 'SaaS-based monitoring' over advertising or agency models.
Why MMU is an MIT open-source CLI, not a paid SaaS. Details the solo builder workflow fit, the 3-tier 'What-How-Auto' revenue model, and explicit validation metrics.
Documenting how 534 SaaS launch checklist items were derived from 80 service analyses, 12 guidelines, and 5 real-world failures, including the P0-P3 priority logic.
Analyzing the difference between 'code complete' and 'product complete' through the 3-week post-feature work (payment stability, security, legal docs, SEO, etc.) which accounted for 88% of the effort.
10 key changes for transitioning an MVP to commercial SaaS: security hardening, JWT auth, KO/EN i18n, and payment automation to build a 'payment-ready' service.
Recording the 3-day MVP build for WICHI during the Jocoding Hackathon, covering tech stack choices (FastAPI, React, Supabase) and priorities for creating a 'working product' under tight deadlines.
Comparative analysis of Lemon Squeezy (MoR) and Stripe for Korean solo SaaS builders, providing a practical guide on global tax compliance, fees, and business registration.
Recording the 24-hour pivot of WICHI to an independent SaaS after a hackathon rejection, covering i18n implementation, SEO setup, and monetization roadmap restructuring.
Migration from Lovable ($25/mo) to Vercel ($0) including build pipeline reconfiguration, documenting the frontend hosting transition process.
Essential security checklist for solo SaaS builders. Defense against five critical OWASP Top 10 vulnerabilities and real-world security configuration cases improved for WICHI.
