Senior paid media, with nobody in between.
I am one person with 14+ years on Google Ads, Meta Ads and LinkedIn Ads for DTC, SaaS and B2B brands across the US and Europe. Brands hire me directly, and agencies bring me in when an account needs a senior operator without adding headcount. Either way you talk to the person who runs the account, because that is the whole arrangement.

Performance marketing, built on data
I'm an independent paid media strategist with 14+ years of hands-on experience managing Google Ads, Meta Ads, LinkedIn Ads, and programmatic campaigns. I've worked across B2B, B2C, SaaS, healthcare, and pharma, always with the same focus: turning ad spend into measurable pipeline and revenue, not just clicks.

The same practice also runs googleadsfreelancer.com for US businesses hiring a freelance Google Ads specialist, and ppcconsultancy.uk for UK and Irish businesses.
Brands I've worked on
Fourteen-plus years across agency, in-house and freelance roles put me on accounts with very different economics: SaaS and subscription products such as Intuit QuickBooks, Skillshare and Pontomais, global consumer brands such as Shell, Timberland and Amazon Prime, home services companies such as an HVAC and plumbing business in Houston, and companies in telecom, education, healthcare and e-commerce. Through Underscore Marketing, a US agency, I also worked on oncology, rare disease and gene therapy brands.
What carries over to your account is pattern recognition: how a trial-to-paid funnel differs from a lead form, which conversions each business can actually measure, and where spend usually leaks.

Direct access, one person
A paid media agency, an in-house hire, or one senior operator
A paid media agency, an in-house hire and an independent operator solve different shapes of problem, and plenty of my work comes through agencies. Here is the honest version of the trade, so you can tell which one this account needs.
| A full agency team | Working with me | |
|---|---|---|
| Who runs the account | Often not the person you met in the pitch | The person you spoke to |
| Who you talk to | An account manager relaying questions | Nobody in between |
| What you pay for | The team, the coordination, the overhead | The work |
| Capacity | Many accounts, many hands, always available | Few accounts at a time, which is the limit and the point |
| When the agency is the right call | Multiple markets at once, round the clock coverage, or a volume of creative production one person cannot physically deliver. If that is the account, the agency is the right call, and I will say so. | |

Real engagements, real numbers where I can publish them
Where I can publish numbers from the account, they are here with what they mean. Where the data is confidential, by contract or because it was an employed role, I describe the work and not the figures. All case studies.
HVAC and plumbing company, Houston, TX
Freelance · May 2025 to Feb 2026The Challenge
- Very expensive clicks, with dozens of local competitors on the same searches
- ZIP code choices, where the areas with the most potential cost the most
- Seasonal swings between cooling and heating
The Strategy
- Services, areas and budget adjusted as results came in
- Generic and brand campaigns read together, not in isolation
- Cost per conversion, calls and bookings tracked by service, area and season
Google Ads and Performance Max in one of the most competitive local markets in the US, with expensive clicks, ZIP code choices and seasonal demand. The performance data is confidential by contract, so the case covers the work and the lessons, not the numbers. Read the case.
Trutek, truck suspension parts, Brazil
Google Ads · since 2020Cumulative account history since 2020: 5,707 clicks and R$ 63.61 per conversion. Conversions are contact actions recorded by Google Ads, not sales. I also created the brand identity and built the site. Read the case.
Healthcare
Five years in the sectorI have also worked in paid media in healthcare. Nothing from that work is published anywhere on this site: no employer named, no budgets, no results, no internal detail. It is listed only because it is where a large part of my healthcare experience comes from.

Common questions
What does a Google Ads specialist do?
Manages and optimizes pay-per-click campaigns on Google's advertising platform: keyword research, ad copywriting, bid management, landing page optimization, conversion tracking, and ongoing performance analysis to maximize your return on ad spend.
How much does it cost to hire a PPC specialist?
A fixed-price audit, or ongoing management on a flat monthly fee that is never a percentage of ad spend, month to month. You get a written quote after a short first call. How it works is on the pricing page.
What changes when one person runs the account?
You get senior attention on the account every month, and the person who answers your question is the person who made the change. Fewer handoffs, faster answers: you communicate directly with the person managing your campaigns, which usually means faster response times and more accountability.
Which platforms do you manage?
Google Ads (Search, Display, Shopping, Video), Meta Ads (Facebook and Instagram), and LinkedIn Ads, with experience in Microsoft Advertising and programmatic platforms. Google Ads is my primary area of certified expertise.
How quickly can I expect results?
Campaigns can start generating traffic and leads immediately after launch. Meaningful optimization typically takes 2–4 weeks as data comes in, with most clients seeing significant improvement within 60–90 days. A live dashboard and a monthly written read keep you tracking progress from day one.
Tell me what you are working with
