Custom CRM for managing internal processes and marketing of the largest indoor amusement park in Moscow.

Achievements:
* Developed an interactive filter constructor for DB data queries (nested condition groups, queries across related entities). Its adoption for client selection sped up marketers' mass-mailing workflows 6x (from half an hour down to 5 minutes)
* Built an internal email/push mailing module with a built-in visual drag-and-drop template constructor — dropping expensive specialized services saved the company almost 16 thousand rubles per month
* Designed and rolled out a Spec-Driven Development infrastructure based on the OpenCode AI agent: a hierarchy of subagents, custom skills and system rules sped up feature delivery for the whole team by about 20%, and automating Code Review cut its time by 30–40%
