AI-Assisted Software Engineering • Security Fixes • Quality Gates

Samuel Bostock

I build software with coding agents — and the specs, quality gates and review loops that make their output trustworthy.

I'm a top-10 contributor to Open Mercato, an open-source AI-engineering framework for CRM/ERP and commerce, with 45 merged pull requests — mostly security and correctness fixes. Before that, I founded and ran a software business for ten years: 12 commercial products and around 20,000 customers.

How I can help

Engineering with coding agents, backed by a decade of shipping and supporting real products.

AI-Assisted Engineering

I design the workflow agents work in: spec templates per task type, an independent quality gate that re-verifies every change before it's published, browser-based self-QA, and review loops that keep pull requests moving. My Open Mercato work runs entirely through this pipeline (Cezar + Claude Code).

Security & Correctness

Authentication and sessions, tenant and organization scoping, webhooks, payment-gateway handling, AI-agent safeguards, concurrency and undo/redo integrity — fixed with regression tests, upgrade notes for behaviour changes, and follow-up issues for known limitations.

Product & Customer Experience

Ten years of running a commercial software business end to end: requirements, releases, licensing, payments (WordPress/WooCommerce, Stripe, PayPal) and supporting around 20,000 customers — so I understand how technical decisions land with real users.

Experience built around real products and customers

More than a decade of practical responsibility across software, support and online operations.

Open-Source Contributor — Open Mercato

Security and correctness fixes across an open-source AI-engineering framework for CRM/ERP and commerce — 45 merged pull requests, with more approved in the merge queue.

  • Authentication, tenant scoping, webhooks, payment gateways, AI-agent safeguards, forms and portal access.
  • Delivered through an agent-driven pipeline I designed: spec templates, an independent quality gate, self-QA and automated review loops.
  • Defects are scouted, reproduced with a failing test, fixed, and only then filed — together with their fix.
