Helix.ai

WithSeismic is an independent product-engineering business that builds software, analytics and marketing automation for client teams. As founder and sole operator, the role spans finding the commercial problem, scoping the work, designing and building the solution, and supporting it after launch.

• Delivered 100+ product-engineering engagements over 10 years for clients including Framer, The Motley Fool, Groupon, Contra and Weedmaps.
• Scoped, priced, delivered and supported every technical build independently.
• Runs a fixed ten-business-day, £12,000 Revenue Loop Sprint that finds one material commercial leak and ships one corrective system into production.

Benson shows online stores which coupon extensions and AI shopping agents are in their sessions and what they cost, then lets them hide, cap or replace them with a holdout behind every change. The founder and technical lead role covered building, operating and selling the original getBenson platform, then reacquiring the brand and rebuilding it for the relaunch at trybenson.com.

• Rebuilt Benson from an empty repository to a public relaunch at trybenson.com in ten days, against an original roadmap of 14 to 18 weeks.
• Wrote the product as 44 PRDs and ran the build as an orchestrator, with AI agents delivering each task through tests, adversarial review and simplification: 836 commits and 785 test files in under two weeks.
• Shipped ten apps and fifteen packages: a 2.5KB storefront loader, ingest on Redis Streams, Postgres with row-level security, a dashboard, an embedded Shopify admin, a WooCommerce plugin, a Cloudflare edge detector and an MCP server.
