Senior Rails developer, 11 years. 9 years on a fintech platform in 9+ countries (payment integrations, client APIs, a Rails 5 to 6.1 upgrade of a very large codebase). In 2026 I built two products alone: SnapDub (https://snapdub.ai), an AI video-clipping SaaS with 5,700+ users and paying subscribers, and Store Pickup Alert (https://storepickupalert.com), which had paying customers within three days of launch. Integrations on GitHub: https://github.com/aheront. Looking for a product or founding engineer role, B2B contract.
