Charles Heller

Quality-Driven Software Engineer

I started in QA, test automation, and test management on enterprise projects — then expanded into shipping modern web products myself. Today I work as a quality-driven software engineer: I build reliable applications and bake testing, architecture, and maintainability in from day one.

Experience

Test Manager · Swiss Life

Multi-year · Enterprise CRM & digital delivery

Lead quality for complex enterprise delivery — aligning teams on risk, coverage, and release readiness across CRM and related digital workflows.

  • Owned test strategy in agile delivery for multi-team CRM programs.
  • Drove automation with Playwright, TypeScript, API testing, and structured testdata practices.
  • Partnered with engineering and product so quality became a shared delivery signal — not a late gate.

Software Engineer · Freelance / Projects · Independent

Ongoing · Web products & automation

Building modern web applications while applying the same quality systems used in enterprise environments.

  • Designed Playwright / Vitest suites and CI-ready automation as part of product delivery.
  • Bridged QA depth and engineering ownership — from architecture decisions to shippable releases.
