I step in when product growth fails.
Low activation.
Weak retention.
Users don’t reach value fast enough.
Revenue doesn’t scale with traffic.
I work with founders and product teams to fix that at the product layer.
Not by redesigning screens.
By restructuring how the product drives activation, habit, and trust.
-
I’ve worked across:
💊 Bayer (S&P Global 100) • 🦊 Foxit (AI, 700M users) • 🐻 MindsDB (AI, YC) • 📦 Archlet (AI, $16M+ raised) • 🌱 PictureThisAI (100M Users, AI) • ⚡️ SonicLabs (DeFi) • 🏥 Huma (HealthTech) • 🏢 BairesDev
I'm ranked in the top 1% on Upwork and hold Expert Vetted status.
-
What I actually do
When I join, we focus on:
• Activation baselines
• Onboarding drop-offs
• Time-to-value
• Retention loops
• Monetization logic
• Experiment frameworks
• Instrumentation clarity
• LTV expansion
I help teams move from:
“Users signed up”
to
“Users reached value and stayed.”
-
How I work
I operate at product strategy level.
I define:
• Clear problem thesis
• Target user and job-to-be-done
• Growth bottlenecks
• Metrics that actually matter
• Experiment roadmap
• Execution direction for design and engineering
I align product decisions with business outcomes.
No pixel pushing.
No random redesigns.
No feature shipping without metric intent.
-
I’m a strong fit if
• You’re building AI, Fintech, Crypto or SaaS
• Growth is inconsistent or plateauing
• Activation is weak
• Retention feels fragile
• Your product is powerful but misunderstood
• You want product thinking, not just UI work
-
Not a fit if
• You want cosmetic redesign only
• You don’t measure activation or retention
• You’re looking for the cheapest execution
• There’s no ownership or decision authority on your side
-
I’m a 2x startup founder.
I understand runway pressure.
Board expectations.
Growth targets.
Team constraints.
If your product needs sharper activation, stronger retention, and clearer monetization logic, let’s talk.

Two-second version:
I'm the co-founder of Cartenio, a design studio that fixes underperforming websites and redesigns products. I design and build conversion-focused Webflow sites, and I give founders' MVPs the polished UI/UX they need to look credible and convert. I've helped Nestwell, a healthcare startup, go from zero to an MVP that raised their $1.5m seed round, and I've been trusted by enterprise clients such as Kickstarter on web design work.
Projects are fixed-price only. I'm not accepting hourly work at this time.
Longer, sit-down version:
Here's what that actually looks like when we work together:
I'm usually brought in when a business or founder has one of three problems:
- their site looks dated or off-brand,
- it's confusing, or
- it gets traffic but doesn't convert into real leads and opportunities.
Lately, I've also been working with founders who've built an MVP through vibe coding or a fast first build. The product works, but it looks rough, and that's costing them with users and investors. I come in and give it a fresh, professional UI/UX without slowing their momentum.
I help you fix that by combining strategy, UX, and Webflow execution into one process:
We clarify who you're trying to reach, what you want them to do, and what makes you different in plain language. We map a simple, logical structure for your site so visitors know exactly where to go.
I design the key pages and flows so your brand finally feels as good online as it does in real life.
Then I build it in Webflow in a way your team can actually maintain without breaking things.
On the product side, I've worked with Nestwell, a healthcare startup, where I helped them go from zero to an MVP, providing them with a Webflow site, basic branding, product design, pitch deck, plus marketing support that landed them $1.5m in seed funding. On the enterprise side, I've been trusted by the likes of Kickstarter on web design projects, which means I'm comfortable collaborating with more mature teams and processes. I don't just "make it pretty"; I care that it works in the real world.
Most clients come to me because they want a partner who will think with them, push back when something won't help conversions, and stay involved long enough to make sure the handoff is smooth. I'm happy to advise on roll-out across the rest of your brand, simple automations, and how to get the most from Webflow once we launch.
On Upwork, I keep things straightforward: I work on fixed-price projects that typically start from $5k+, focused on full new sites, major redesigns, and MVP/product redesigns rather than tiny tweaks or one-off fixes.
If that sounds like where you're at, share a bit about your business, your current site or product, and what "success" would look like for this project, and I'll let you know quickly if I'm the right fit or not.

Current focus: AI agents, automation workflows, and product analytics. Recently shipped an end-to-end AI agent for a B2B SaaS client (n8n, HubSpot API, Gemini) and co-built a real-time web app from scratch - because the best way to stay sharp is to keep building.
What I can help you with:
- AI agent design and automation workflows
- Product strategy, roadmapping, and prioritization
- Technical project and program management
- Product analytics setup and dashboards (PostHog, Google Analytics)
- SaaS and MarTech product operations
Focus: AI Product Management • SaaS & MarTech • Product Analytics • LLM Integration • Automation Systems

Most marketers talk about pipeline. I build it.
I am a B2B Demand Generation and AI Search strategist with 10 years of experience helping companies in SaaS, Fintech, Tech Staffing, Ecommerce, and IT Services grow revenue through channels that actually convert.
Here is what that looks like in practice:
I helped a corporate gifting brand get cited and referenced by ChatGPT, driving 126 referral visits from ChatGPT in a single 30 day period, an 88% jump from the previous period. That is not SEO. That is Generative Engine Optimization and it is where search is heading.
I managed a $25,000 per month Google Ads account, cutting cost per click by 35% and growing conversions by 40% through audience segmentation, A/B testing, and disciplined bid strategy.
I reduced customer acquisition cost by 40% and grew organic traffic by 50% for a Fintech brand by rebuilding their SEO and SEM framework from the ground up using Ahrefs and SEMrush.
I delivered a 60% increase in organic traffic for a B2B marketplace by restructuring SEO architecture, building topical authority, and aligning content with high intent buyer searches.
I accelerated MQL to SQL conversion by 22% through HubSpot lead scoring, behavioral triggers, and automated nurture sequences built around the actual buyer journey.
What I actually do:
I own full funnel B2B demand generation strategy across inbound and outbound. I run ABM campaigns on LinkedIn targeting ICP accounts with personalized messaging. I build and manage Google Ads and Meta Ads campaigns with real budget accountability. I do off page SEO, white hat link building, digital PR, and expert quote placements that build durable domain authority. I optimize for AI search visibility so your brand shows up when buyers ask ChatGPT, Perplexity, or Google AI Overviews questions that matter to your business. I set up multi touch attribution in GA4 and Google Tag Manager so you always know what is driving revenue and what is wasting budget.
Tools I work with every day: HubSpot, Marketo, Salesforce, ActiveCampaign, Ahrefs, SEMrush, Google Search Console, GA4, Google Tag Manager, Unbounce, LinkedIn Ads, Google Ads, Meta Ads, Hotjar, PostHog.
I do not do bulk link packages, PBNs, or vanity metric reports. I work with clients who want real outcomes and are serious about building something that lasts.
