Freelance presentation and pitch deck design

I’m Maria Kalavrezou, a senior freelance graphic designer in the UK. I design executive presentations, pitch decks and presentation templates in PowerPoint and Keynote, for corporate teams and for agencies pitching for new business. The job is to turn a strategy, a set of findings or a sales argument into slides a room can follow.

Clients

Who it’s for

  • Leadership and communications teams preparing an executive or board presentation
  • Agencies that need a senior designer on a new‑business pitch
  • Marketing teams that need a sales or capabilities deck in the company brand
  • Teams that need a PowerPoint or Keynote template other people can build slides from

Scope

What’s included

Executive and board decks
The story, the slide structure and the design, built inside your brand guidelines.
Pitch decks and pitch concepts
Concept development and the deck itself, for agency and in‑house pitches.
PowerPoint and Keynote templates
Master slides and layouts your team can keep using after the project ends.
Charts, diagrams and infographic slides
Data and processes redrawn so the point of each slide is obvious.

Experience

Where I’ve done this

Decks have run through every role I’ve had. At Ogilvy I produced presentation materials for B2B clients including Mastercard, Vodafone, Iron Mountain and Oracle. As brand manager at Cushman & Wakefield I looked after stakeholder-facing presentations inside a global brand system. As a freelancer I’ve designed pitch concepts and executive-facing decks for agencies and brands, and the Tokenise brand guidelines were delivered as a slide system.

Questions clients ask

Do you design in PowerPoint, Keynote or both?
Both. I design presentations and templates in PowerPoint and in Keynote, and I use Figma, Illustrator and InDesign alongside them when a deck needs custom graphics.
Can you work within our existing brand guidelines?
Yes. Most of my presentation work has been built inside a company’s existing brand guidelines, including global brand systems at Ogilvy clients and at Cushman & Wakefield, where I was brand manager.
Can you help with a pitch deck for a new-business pitch?
Yes. I’ve worked on pitch concepts and pitch decks as an agency designer and as a freelancer, from the early idea to the finished slides.
Can you redesign a presentation we already have?
Yes. Send the existing deck with a note on who it’s for and what it needs to achieve, and I’ll come back to you on scope and timing.
