Overview

+

Quest is a safari quotation platform for tour operators. I co-founded Quest as CTO and lead a 3-person engineering/product team building the platform: operator dashboards, admin tools, travel requests, itinerary planning, pricing, branded PDF generation, quote email delivery, content libraries, billing, and release workflows.

+ +

Problem

+

Tour operators often build quotes through spreadsheets, scattered assets, manual document editing, and repeated back-and-forth with travelers. Quest turns that workflow into structured software: requests become itineraries, pricing becomes traceable, and final proposals become branded PDF and email outputs.

+ +

What I Built

+ + +

I contract with xAI's Human Data software-engineering track to create and review high-quality coding data for training, benchmarking, and improving large language models.

Work Scope

+ + +

Why It Matters

+

This work sits close to the quality layer of AI coding systems: identifying which outputs actually satisfy real software-engineering tasks, why they work or fail, and how evaluation evidence should be grounded in code behavior rather than vibes.
