Christopher H.

Full-Stack Developer | Web Apps, Automations, APIs, Scrapers & Fixes

I build and fix software, start to finish: web apps, scripts, automations, integrations and data pipelines. Fixed prices, clear written updates, and usually a working demo or a concrete plan right in my proposal, so you can see the work before you hire. Why you can trust me with your project: I designed, built and run ParentEdge on my own, a live web app plus an Android app on Google Play. Behind it is everything a real product needs: accounts and Stripe payments, a PostgreSQL database on Supabase, email, analytics, and a data pipeline that found, verified and published over 20,000 organizations across 207 US regions, plus a 585-page generated content library that ranks on Google. I also built and maintain a database of over 40,000 verified business contacts with the sending and tracking tools around it. What I take on: - Web apps, new features and bug fixes: React, Next.js, Node.js, TypeScript, Python, PostgreSQL, Supabase, Firebase - WordPress, Shopify and website fixes: broken pages, speed, plugins, Cloudflare and DNS - Automations and integrations: APIs, webhooks, Google Sheets and Apps Script, Airtable, Zapier, Make, n8n - Data work: scrapers, cleanup and dedupe, lead lists, dashboards and reports - Small builds: browser extensions, bots, scripts and internal tools that save someone hours every week How I work: you get a clear plan before I start, progress updates in writing, and a short handover note explaining what I changed and how to adjust it later. If something in your brief is unclear, I'll ask one good question instead of guessing. My background before building products was technical writing for publishers like Wiley, so the notes and documentation you get are clear and easy to follow.
