Zeno was born out of a personal need to maintain momentum while building projects. Consistency is the hardest part of shipping products, and Zeno acts as an accountability partner.
The application features a robust streak-tracking engine that handles logging activity intelligently.
Core capabilities:
- Analytics: It provides users with analytical dashboards that highlight performance trends over time, helping them identify their productivity patterns.
- Performance: High-speed queries to ensure fast, snappy dashboards.
- Data Modeling: Complex time-series data aggregation for streaks and activity logs.
From a technical perspective, building Zeno involved deep dives into caching and query optimization.
