M-Pesa Python SDK for Payment API Integration
Built a Python SDK for integrating M-Pesa APIs, including STK Push, C2B, and B2C payment workflows. The SDK simplified authentication, request validation, transaction handling, and error management so developers could integrate M-Pesa services with a clean and consistent API pattern.

Last Seen - Places disappear. Their stories don't have to.
Last Seen is an archive of lost places and the memories people left behind. A living record of the places that shaped us, before they disappear from memory as completely as they have from maps.
The research
Before writing a line of code I posted to Reddit. "What closed place do you still think about?" Three subreddits. Three cities. 217,000 views. 1,652 replies. The Astoria. Shunt Vaults. CBGB. Florent. The problem was real before I built anything.
The Figma workflow
Figma Weave generated the visual language, aged paper textures, film grain overlays, archival map treatments. The Design Agent built the complete design system from a single prompt, colour styles, typography, eight components, page layouts, brand guidelines. The result is a 16-frame horizontal brand identity deck published to the Figma Community.
Two Figma Make widgets built and published to Community, Memory of the Day and Still Here, pulling real memories from a live Supabase database in real time.
The product
Next.js, TypeScript, Tailwind, Supabase, Mapbox GL JS, Vercel. 103 places across five cities. A heatmap showing where memory concentrates across continents. Real memories from real people. An admin queue, rate limiting, auto-geocoding, profanity filtering, i18n across six languages.
825 unique visitors in three days. The archive keeps growing.
The workflow
Reddit validation, Figma Weave, Design Agent, Figma Make, live product. In 24 hours.
