Hello! My name is Teresa and I’m a Portuguese native speaker, living in Portugal.
I hold a Master’s degree in Bioengineering and a PhD in Chemical and Biological Engineering. My academic and research background has provided me with strong analytical skills, a highly structured way of thinking, and extensive experience working with complex data sets.
Throughout my scientific training, I developed a strong attention to detail, critical thinking, and the ability to extract meaningful insights from experimental and technical data. I am comfortable working in data-intensive environments where accuracy, logic, and structure are essential.
I am currently expanding my skills in Data Analysis, with training in Excel, SQL, and Python, and I am particularly interested in data cleaning, data organization, and analytical problem-solving.
I am now looking for opportunities where I can apply my scientific and analytical background to real-world data tasks, while continuing to develop professionally in the field of data analysis.
Hope you consider my application!

🎯 Building a product shouldn't feel like throwing darts blindfolded. I help startups, entrepreneurs, and product teams get real feedback on their ideas, website, or app, so that they can confidently build what users and the market actually need.
I am a mixed-methods UX researcher with 8+ years across tech start-ups, consultancy, and the not-for-profit sector. By blending behavioral science with data storytelling, I've powered products across the USA and Europe in gaming, e-commerce, digital communities, (open-source) SaaS, and LGBTQ+ services, to name a few.
🦜 I can compliment you in 4 languages (Bulgarian, English, Dutch, and Portuguese)
🥋 I love engaging in sports such as fitness, calisthenics, and jiu-jitsu.
Here's how I can help you:
✅ Usability testing – Find out where users struggle before you invest more in building.
✅ User interviews – Go beyond what users say and understand the “why” of behavior.
✅ Surveys – Validate assumptions at scale before you act on them.
✅ Competitor analysis – See where rivals fall short so your product can fill the gap.
✅ Journey maps – Align your team on priorities and stop solving the wrong problems.
✅ Heuristic evaluation – Get an expert audit of your product against proven principles.
✅ Empathy maps – Build a shared understanding of your users across your team.
✅ Market research – Learn about your audience, your opportunity, and your risks.
✅ Data analysis – Turn behavioral and product data into a clear direction, not noise.
And more, tailored to where your product is and what decisions you're facing.
Some examples of my work:
🏳️🌈 InReach (Tech nonprofit | B2C | Mobile app): The product team needed clarity on what to refine next for a free platform connecting LGBTQ+ people to verified services. Through remote moderated usability tests with 5 service providers, I uncovered what was holding users back and delivered 5 prioritized development recommendations. My recommendations gave the team an evidence-based roadmap instead of competing opinions.
🎮 Solsten (Scale-up SaaS | B2B | AI-driven audience insights): When a growing SaaS needed to improve how 19 game studios integrated their data into the platform, guesswork wasn't an option. Working closely with the data team, I mapped the full integration flow, surfaced 4 major pain points, and handed over 10 actionable takeaways. As a result, I turned a complex technical relationship into a smoother, more trusted product experience.
💪 Solo founder (Freelance | B2C | Health & wellness SaaS): A founder knew something wasn't clicking with his desktop app for sport challenges, but couldn't pinpoint what. Through usability tests with 5 enthusiasts craving community around their health goals, I identified 9 usability issues. Not only did he receive tactical improvements, but also a strategic direction for a rebrand that helped him move forward with confidence rather than guesswork.
📩If you're building something and want research that actually moves the needle, send me a message and let's figure out the right starting point.

I help businesses stop leaking leads, time, and sanity.
I’m an experienced Account Manager and Marketing Operations specialist who works at the intersection of strategy, automation, and execution. My job is making complex systems simple, reliable, and scalable - while keeping clients informed, confident, and happy.
Over the years, I’ve worked with agencies, startups, and growing businesses to improve their marketing and sales infrastructure, streamline operations, and turn messy workflows into clean, automated systems that actually work.
What I do best:
Account & Client Management
Acting as the main point of contact between clients, tech teams, and stakeholders
Managing multiple accounts without things falling through the cracks
Translating “business problems” into clear technical solutions
Marketing Ops & Automation
Zapier, n8n, GoHighLevel, HubSpot, Hyros, Stripe integrations
Lead routing, lifecycle automations, CRM cleanup & optimization
Error handling, edge cases, and “what happens when this breaks?” planning
Systems Thinking
Auditing broken or inefficient funnels
Reducing manual work and human error
Designing workflows that scale instead of collapsing under growth
Results I’ve helped deliver:
Increased email open rates from 2–3% to 15–25%
Eliminated lead delivery failures and duplicate records
Built automation systems that saved teams hours every week
Smoothed client transitions with zero downtime or confusion
I’m known for being reliable, proactive, and calm under pressure. If something breaks, I don’t panic — I fix it, explain it clearly, and put safeguards in place so it doesn’t happen again.
If you’re looking for someone who:
understands both people and systems
communicates clearly (no tech-bro nonsense)
actually takes ownership of outcomes
…then we’ll probably work very well together.

I build the systems your team runs on: automation pipelines, AI-integrated workflows, data systems, and the Qualtrics programs and operational tools that connect them. I am a senior Qualtrics expert with 5 years of experience working directly at Qualtrics on service and implementation teams. For 8+ years I have designed and built systems for SMBs, nonprofits, and universities across the US, Europe, and Australia.
The work varies. Sometimes a client needs a fully automated delivery pipeline, sometimes an AI layer that reads and sorts incoming work, sometimes a Qualtrics program integrated into their CRM, sometimes an Airtable system to replace five disconnected tools.
Most consultants pick a lane: one tool, one layer, one type of problem. That works, until you realise you need three of them and a project manager to coordinate between them.
I work differently. I take the problem end to end: understand what is actually broken, design the full solution, and build it. You work with one person who owns the outcome from the first call to handover, rather than being passed between a sales lead, a project manager, and a rotating cast of subcontractors. On complex, production-grade AI builds I partner with a senior AI architect I work with directly, which adds staff-level engineering depth while keeping that single point of contact intact. The result is a system built around your specific workflow, that your team can maintain after I leave.
⚙️ WORKFLOW AUTOMATION
I build automation pipelines using Make, n8n, and Zapier, connecting platforms like Salesforce, Airtable, Google Suite, SendGrid, and custom APIs. A lot of this work has nothing to do with surveys: automated client delivery workflows, document generation, CRM update pipelines, data processing systems. When off-the-shelf tools are not the right fit, I also build custom lightweight applications using AI-assisted development, delivered in days rather than months.
⚙️ AI INTEGRATION
I build AI into the systems you already run, wherever it removes manual work or surfaces the answers you need faster. I stay tool-agnostic, using Claude, the OpenAI API, or custom builds depending on the job, rather than forcing one approach onto every problem. In practice that has meant reading and triaging incoming emails and form submissions, pulling clean structured data out of PDFs and thousands of open-text responses, auto-generating branded reports straight from a data source, and scoring or screening applications against set criteria. For complex, production-grade work I partner with a senior AI architect, so what I hand over is reliable enough to run unattended rather than a clever demo that breaks in week two.
⚙️ DATA SYSTEMS & OPERATIONS
I design and build Airtable systems for operations, CRM, project management, and client delivery. I also design process flows and system diagrams for business operations: mapping how work moves, where it breaks, and what a rebuilt version should look like. This is often where automation projects begin, and sometimes it is the whole project.
⚙️ SURVEY & RESEARCH SYSTEMS [QUALTRICS EXPERT]
I spent five years at Qualtrics in senior implementation and operations roles and hold both the CoreXM and CustomerXM certifications. I design CX, EX, and research programs with custom JavaScript logic, workflow automation, CRM integrations, and analytics dashboards. Most clients come to me when Qualtrics needs to do more than collect responses: eligibility screening, automated distribution, branching logic tied to external data, or full program infrastructure built from scratch.
WHAT I BUILD:
→ Automation pipelines across Make, n8n, Zapier, and APIs
→ AI integrations: triage, data extraction, automated reporting, scoring and screening
→ Airtable systems for operations, CRM, and project delivery
→ Process design and system diagrams for business operations
→ Qualtrics programs with custom logic, integrations, and reporting
→ End-to-end data workflows: collection, transformation, storage, output
→ Custom lightweight apps when the workflow requires it
WHY CLIENTS WORK WITH ME:
→ I build the complete system, not isolated pieces
→ One accountable owner from scope to handover, never passed around a team
→ Staff-level AI engineering on complex builds, through a senior architect I partner with
→ The output is something your team can maintain and build on after handover
$1.7M in margin recovery. 120k+ contacts automated. 500k+ feedback records processed.
