If customers join full of excitement but gradually lose momentum,
If onboarding feels rushed, unclear, or inconsistent,
Or if your team is constantly busy but important initiatives still get delayed,
The challenge likely isnโt growth.
Itโs a gap between customer success and operational alignment.
Thatโs where I come in.
I support SaaS, EdTech, and service-based businesses in building structured onboarding frameworks, strengthening retention, and bringing clarity to customer-facing operations. In short, I ensure customers donโt just sign up, they engage, adopt, and continue growing with your business.
With over 4+years of customer-facing experience and a strong focus in SaaS and AI-driven startups, I specialise in everything post-sale. From strategic onboarding to renewals and expansion, I design experiences that drive adoption, reduce churn, and increase long-term revenue. I donโt just manage accounts, I build scalable success systems that grow alongside the company.
Customer Success & Retention
โข Structured onboarding journeys that improve activation
โข Lifecycle planning to reduce churn and increase lifetime value
โข Proactive engagement strategies that build trust
Account Management
โข High-touch client relationship management
โข Expectation alignment and structured check-ins
Project & Operations
โข Cross-functional coordination across teams
โข SOP creation and workflow optimization
โข CRM visibility and accountability improvements
I donโt just manage tasks. I build operating systems around your customer journey.
Results include:
โข 50%+ improvement in customer retention and satisfaction
โข Up to 60% reduction in operational inefficiencies
โข Management of 15+ concurrent high-priority initiatives
โข Onboarding systems that significantly improved adoption
Whether you run SaaS, EdTech, or a service-driven business, the fundamentals are the same. Customers need clarity. Teams need alignment. Processes must scale.
I design systems that intentionally guide customers from their first interaction through long-term loyalty, while helping internal teams operate with clarity and consistency rather than pressure and guesswork.
I combine empathy with sharp commercial thinking. Iโm deeply relationship-driven, but equally data-led, using tools like HubSpot, ChurnZero, Mixpanel, ProfitWell, Intercom, ClickUp, and Asana to track health, anticipate risk, and uncover growth opportunities before theyโre obvious.
Your customers donโt need more support. They need better strategy, stronger partnership, and someone who knows how to turn retention into revenue. My focus is always the same: turning users into long-term partners and building customer success functions that scale with confidence.
And fortunately, you're here reading the profile of that person who would meet and exceed your expectations.๐ฏ
Do not hold back in reaching out to me. Kindly click on the โ๐๐ง๐ฏ๐ข๐ญ๐ ๐ญ๐จ ๐๐จ๐โ button on this profile to interact more with your project needs and how I may grow your business with my expertise.
Thank you.

Hey there, here is what I actually do, end-to-end for your business/brand:
------------------------------------------------
1. Full-Funnel Paid Media Across Every Channel That Matters
Meta Ads โ Advantage+ Shopping Campaigns (ASC), Catalog Sales, Advantage+ Audience, manual campaign architecture when ASC isn't the right call
Google Ads โ Search, Shopping, Performance Max (PMax), YouTube, Demand Gen โ including PMax asset group structuring and search term sculpting
TikTok Ads โ Smart+, Spark Ads, creative-led testing frameworks
LinkedIn Ads โ ABM, lead gen forms, conversation ads (for SaaS clients)
AppLovin, Reddit, Pinterest, Snapchat โ where the unit economics support them
CTV / Programmatic / Retail Media โ DV360, The Trade Desk, Amazon Ads, Walmart Connect when the brand is ready for it
I don't push channels for the sake of channels. I run the channels that produce incremental, profitable revenue for your specific business โ and I prove it with data.
------------------------------------------------
2. Measurement Frameworks That Actually Tell You What's Working - This is what separates senior operators from button-pushers. I build measurement systems on the trifecta:
MMM (Media Mix Modeling) for strategic budget allocation across channels
MTA (Multi-Touch Attribution) for daily tactical decisions
Incrementality testing (geo-lift, holdouts, time-based experiments) as ground truth
Platforms I operate in: Triple Whale, Northbeam, Hyros, Rockerbox, Polar Analytics, GA4, Looker Studio, Mixpanel, Amplitude. Server-side tracking via Meta CAPI, TikTok Events API, Google Enhanced Conversions โ because client-side pixel data alone hasn't been reliable since iOS 14.
------------------------------------------------
3. Creative Strategy + AI-Augmented Production - Creative is now the single biggest performance lever on Meta and TikTok โ bigger than targeting, bigger than bid strategy. I run a structured creative testing system:
Hook testing, angle testing, format testing on a defined weekly cadence
Reading creative data (hook rate, hold rate, thumbstop, CPM-by-creative, fatigue curves) and translating it into briefs
Direct-response copywriting with proven hook frameworks
UGC strategy โ sourcing, briefing, repurposing organic into paid
AI-augmented production stack: HeyGen, Arcads, Creatify, Captions, ElevenLabs, Runway, Kling โ which lets me ship 3โ5x more creative variants per month than a traditional production workflow at the same budget
The hybrid 70/30 framework (AI for high-volume testing, human creators for proven hero concepts) is how I keep creative volume high without the cost spiraling.
------------------------------------------------
4. Financial Modeling & Forecasting
Spend โ revenue โ margin forecasts tied to your actual P&L
CAC and payback modeling by channel and by cohort
LTV modeling and LTV:CAC ratio targets
Blended CAC vs. platform-attributed CAC reconciliation (the gap is usually where the truth lives)
Marginal return analysis for budget reallocation
------------------------------------------------
5. Technical & Analytics Setup
GA4 configuration, custom events, conversion modeling
GTM (Google Tag Manager) โ full implementation and debugging
Server-side tracking โ CAPI, Stape, server containers
Looker Studio / Looker / Mode / Tableau dashboarding
CDPs โ Segment, Rudderstack for SaaS and subscription DTC
Lifecycle stack integration โ Klaviyo, Attentive, Postscript (DTC), HubSpot, Customer io (SaaS)
Catalog and feed management โ Meta Commerce Manager, Google Merchant Center
How I work:
- Budget scale: comfortable managing $50kโ$250k+/month per brand across paid channels
- Reporting: weekly performance reviews tied to business outcomes (CAC, payback, contribution margin), not vanity metrics
- Cadence: structured creative testing weekly, full optimization daily, strategic reviews monthly
- Communication: Slack, Loom, scheduled calls โ whatever your team runs on
- Decision-making: I default to structured testing over intuition. If I can't prove a channel is incremental, I won't ask you to keep funding it
Additional experiences:
-English to Portuguese Translation and vice-versa, IELTS Certified, Native Portuguese.
-Spanish to Portuguese Translation and vice-versa.
-Google Certified (Analytics, Adwords Search, Video, and Shopping)
- Hubspot & Act-on Certified
- Scrum Agile Fundamentals Certified
