Tomasz Stępnik

Salesforce developer since 2020. For smaller companies I am the Salesforce person by the hour: the one you call when something breaks or needs changing.

In brief

I have been building on Salesforce since 2020. Today I am the sole owner of the Salesforce org at a Swedish software company: development, permissions, integrations, production releases. Before that, two years in a Vaillant Group team (loyalty programme, large Apex API, installer portal) and three years at Britenet for clients in education, insurance and finance. Salesforce certifications: Platform Developer I, Administrator, Platform App Builder, Sales Cloud Consultant.

I work with AI every day: Claude Code as a developer, Claude and OpenAI in production automations, Agentforce and Prompt Builder in Salesforce. I built my own MCP server with around 75 tools, exposed to the Claude assistant over OAuth 2.1, and a system where AI wrote nearly all of the code while I owned the specification, review and tests. At the company where I own Salesforce, I took part in rolling out AI in finance, accounting, administration and IT.

How I work

  • On what you have. I do not rebuild systems from scratch. I fix and extend what works.
  • In small steps. Every change checked, with a backup and a way back.
  • On a separate account. Named access, only to what is needed. Handed back at the end.
  • In plain language. Options with pros and cons instead of one right answer. No jargon unless you want it.
  • For time worked. Single jobs, blocks of hours or ongoing support. Quoted per case.
  • With notes. I write down what I did and why, so the next person does not start from zero.

Ways of working together, access security, billing.

Who I work with today

A trading company whose Salesforce was implemented by an outside vendor: ongoing support, about 12 hours a month. A company with Salesforce and a WordPress site: 1–2 hours of changes a month and a larger job every six months, including connecting the site to the CRM. A company with its own mobile app: fixes every two months. Names on request during a call.
