Paid Media Marketer
Luigi

With a touch of Italian flair and a sharp eye for detail, Luigi is the mastermind behind our PPC campaigns, ensuring every click counts. When he’s not fine-tuning ads, you’ll find him scaling rock faces or out on the water with his boat licence in hand—because whether it’s climbing to new heights or navigating uncharted waters, Luigi loves a good challenge.

Web Developer
Louis

Louis is the wizard behind hundreds of websites, effortlessly bringing digital ideas to life with his incredible efficiency and talent. Don’t let his age fool you—he’s a powerhouse of innovation and success, proving that age is just a number when you’re this skilled. A proud Nichiren Daishonin Buddhist, he’s been chanting since age 8. When he’s not building websites, you’ll find him gaming, watching EastEnders, or supporting Liverpool FC. Kitchen skills? Still a work in progress, but he’s getting there!

SEO Executive
Johanna

Johanna, our SEO Executive, has South American roots and has travelled to most continents, bringing a wealth of diverse experiences to her work. She’s also a keen camper van enthusiast—having renovated one and lived in it for a long time, embracing the freedom of life on the road. With her global perspective and SEO expertise, Johanna combines creativity and data to deliver impressive results. Whether optimising search rankings or sharing her travel stories, she adds an adventurous spark to the team.

Head of Design
Iwona

Iwona, a proud Polish native, has lived in both the US and the UK, with each country adding a unique twist to her passion for design. As Sierra’s branding mastermind, she brings big ideas to life, creating stunning visuals and unforgettable brand identities for clients. A true artist, Iwona’s just as at home tickling the ivories on a piano as she is with a hand-lettering pen. When she’s not designing, she’s preparing for her first boxing match—talk about a knockout combo! And when the gloves are off, you’ll find her watching the NBA, hoping for a dunk so epic it makes her spill her tea. 

Finance Manager
Martin

Martin ensures our finances are sharper than his cricket batting average, leveraging years of expertise in financial planning and budgeting. With a proven track record of managing complex accounts, he’s the backbone of Sierra’s fiscal health. When he’s not mastering numbers, he’s juggling cricket matches, badminton tournaments, and basketball games with his sports team—proving he’s just as competitive off the spreadsheets. (We suspect he’s eyeing a trophy shelf expansion.)

Senior SEO Executive
Alice

Alice is the queen of details. With an almost supernatural ability to spot even the tiniest gaps in data, she’s the one who ensures everything runs like clockwork at Sierra. She thrives in the world of numbers, analytics, and operations, where she can make sense of the chaos and turn it into pure magic. When she’s not optimising search rankings, she’s in the kitchen baking (and, let’s be honest, sometimes just cooking for the fun of it). Oh, and she’s a bit of a gamer, too—whether she’s getting lost in Sims 4 or collecting coins in Mario, Alice knows how to balance work, creativity, and a bit of gaming nostalgia.

Founder & Managing Director
Jade

Back in 2017, Jade turned her first-class Business Studies degree, a killer sales record, and a big dream into Sierra Six —a thriving business that’s been making waves ever since. Known for her energy and enthusiasm, she’s appeared in countless press releases, hosted workshops for top universities, and is a proud mentor for Bloom – Women in Digital magazine, encouraging women to claim their spot at the top. When she’s not conquering the business world, Jade’s whipping up experimental dishes, or plotting her next adventure – because why just conquer business when you can conquer the world too?
