Seasonal Price Forecasting of Agricultural Commodities in Nepal

Time-series analysis
  • Analyzed long-term seasonal price behavior of agricultural commodities in Nepal using daily wholesale price data from Kalimati Tarkari Bazaar spanning 2013–2023.
  • Applied Facebook Prophet, STL decomposition, logistic regression, and K-means clustering to identify seasonal patterns, price volatility, and future price trends across six Nepali seasons.
  • Identified strong seasonal dependencies with peak prices during winter (Hemanta) and lower prices during monsoon (Barsha), and achieved moderate forecasting performance with Prophet (average MAE 32.95, R2 0.42).

About

I work on the backend. Most of what I enjoy sits behind the interface: designing services, drawing the boundaries between them, deciding what a database should actually be responsible for, and making the whole thing observable enough that a failure tells you where it came from.

Lately that means AI-native development, treating models as another component in a system rather than the product itself, plus a steady interest in system design, microservices and distributed systems: replication, consistency, and what a service does when its neighbour disappears.

Outside paid work I spend time on developer tooling and infrastructure, and on the technical side of community events with Nepal Open Source Klub.
