Digital marketing · Data analysis

Communication that engages, data that decides.

I built an entire marketing department from scratch: strategy, execution, and the reports that guided every decision. Today I bring that same discipline to data, with SQL, BigQuery and Power BI, because every good decision starts with asking data the right question.

Communication, execution, data

Communication has always been my natural language: understanding an audience and translating that into text, image, or number. I spent time in the corporate world, earned a master's degree in Communication, and, nearly seven years ago, started building digital marketing in practice.

At EnergyCon, I built the entire department alone, from scratch: website, social media, paid traffic, SEO, and the KPI reports that guided every decision. Along the way, I also worked with companies in law, education, retail, and food service, always with the same approach: understand the audience before creating and executing the strategy. That's when I realized I already thought like an analyst, I just needed to learn the right tools.

Every day I sharpen my skills further in statistics, SQL, Power BI, and Python. It's not a fresh start, it's the same discipline applied with more precision. After all, I believe Big Data is the engine of the digital economy, and I want to be among those who know how to interpret it.

The name? Rosossi is how I've been known since university, a blend of Roberta Soares da Silva. It stuck.

A marketing department built from scratch, and a rebrand that prepared the company for the world

ProblemWhen I joined, the company had no marketing or communications department: few employees, and no one handling it. Years later came a second challenge: "Energia em Conserva" had a name that was linguistically restricted to the Portuguese audience and an inflexible logo. After the Painhas group acquired 51% of the company in 2021, the ambition for international expansion made these limitations clear: internal research showed that part of the audience didn't even connect the brand to its core business.
What I didI structured the entire area: websites, Instagram, SEO content, videos, sales presentations, LinkedIn Ads and Google Ads, email marketing, and KPI dashboards. In 2022, I took part in leading the rebrand: from competitor benchmarking (Helexia, Amarenco, EDP, dstsolar) to developing the new identity, inspired by the sunset, with a gradient palette and rounded typography, all the way to the new name, EnergyCon. I documented the entire process in a case study I published as a book.
ResultStrong organic growth on LinkedIn, lower cost per lead, and a first-page Google presence generating real client acquisition. Nearly two years later, the book documented the rebrand's wider business impact: revenue of 25 million euros (+150% versus 2021), team +59%, and LinkedIn with +60% new followers, +97.42% reach and +179% impressions.

Digital presence and lead generation for clients across different sectors

ProblemClients from different sectors (law, education, retail, food service, etc.) needing the same thing: a professional online presence and a predictable flow of qualified leads.
What I didSocial media management, content creation, SEO copywriting, website development, paid traffic campaigns on Meta Ads and Google Ads, and, in some cases, full visual identity work, always adapting strategy and tone to each client's context and audience.
ResultRelationships that last for years across every sector served, the strongest proof of results in a recurring service. In law, Kelly Bortoleto's campaign grew from 224,000 to 291,000 monthly impressions between February and April 2026, with CPM dropping from €1.81 to €1.04. In April alone, that reached 133,603 accounts and 320 WhatsApp messages received.

MethodI consolidated the account's data from day one into a custom dashboard: month-by-month overview, keyword ranking by clicks, cost and conversion, and campaign analysis by bidding phase, by city, and by day of the week.
