Story arc

How this shipped

End-to-end solutions from database to deploymentThree beats: what pressed against the work, how the stack answered, and what changed once it was live.

I · Constraint

The brief

Fishkeepers struggle to maintain consistent water quality and track maintenance across multiple tanks. Existing apps are basic spreadsheet replacements.

II · Build

The craft

Built PWA with trend visualization for water parameters, AI-powered alerts predicting issues before they happen, species compatibility database, and gamification to encourage consistent maintenance.

III · Proof

What moved after launch

Live at myaqualog.com. PWA works offline for tank-side logging. Predictive alerts catch water quality issues 24-48 hours early. Gamification layer keeps logging cadence consistent.
