The person behind Appexo

A clear view.
A hands-on approach.

I’m Michał Wiszenko. I design and build Salesforce solutions, connect systems, and turn useful AI ideas into working software.

Michał Wiszenko / Warsaw, Poland

Independent by design

My work has grown from Salesforce development into solution design, technical leadership, and AI implementation. I enjoy the difficult middle ground: understanding what a business actually needs, then making the technology fit.

Appexo is my independent consulting practice. Today, I provide services through B2B engagements, bringing hands-on delivery experience from larger enterprise consulting programs.

I stay close to the work: architecture decisions, Apex and Lightning Web Components, integrations, and the details that help a team maintain what it builds.

How I approach the work

Understand before building.

Start with the process, the people, and the constraints. A useful technical answer begins with the right question.

Make the decisions clear.

Explain the trade-offs, keep the architecture understandable, and give the delivery team a sound basis to work from.

Stay close to delivery.

Carry decisions through implementation. Pay attention to integrations, testing, and the people who will run the solution.

The foundation

Technical depth. A wider perspective.

A computer science foundation, with a particular interest in how AI can be applied thoughtfully.
