You’ll get clear, well-structured SQL queries designed to answer your key business questions fast. Whether you need to understand your sales data, identify trends, or extract specific insights, I’ll write the exact queries you need — clean, efficient, and easy to follow.
I don’t just deliver code; I make sure you actually understand what the results mean. Every project includes readable queries, organized outputs, and optional summaries that connect the technical work to real-world takeaways.
I’ve built dozens of SQL queries ranging from e-commerce analysis to music sales, business operations, and survey data. I work with SQLite — and always keep performance and clarity as top priorities.

Lead Generation Specialist for Meta
Juan was an absolute pleasure to work with.
My Facebook ad account was shut down due to "compliance" and he was able to not only get my business back up and running, but do so way better than before.
My current ads are running at a cost of $2 a lead and some days it's even better than that!!
When working with Meta it's never an easy or straight forward task. Juan was able to help me make sure my ads were running well, prevent a future issue by ensuring that I had fail safes on my account, and give me enough data to help me in the event that my ads got blocked in the future. My needs and expectations were exceeded.
I am super thankful for Juan's guidance, patience, and support - and wouldn't hesitate for a second to hire him again in the future.

Facebook Advertising Strategy Consultant
Excellent experience with Juan. His expert advice on Facebook Ads, based on a rigorous analytical approach, perfectly optimized my objectives. I appreciated his clear explanations and structured methodology, combining organizational flexibility and responsiveness.
Juan made me understand how precise targeting is to Facebook advertising what a compass is to a navigator.
Moreover, Juan is very friendly, which isn't essential for being an expert, but makes the collaboration particularly enjoyable.

Before we go any further, you’ll probably notice that most of my reviews come from my earlier work as a media buyer and ad creative strategist. I keep them visible because they still reflect the same things clients value today: clear communication, reliability, problem-solving, and a genuine care for results. The only thing that’s changed since then is what I help people with, not how I work with them.
Over the last few years, my path has been anything but traditional. I started my career as a media buyer and ad creative strategist, helping companies scale their products with better messaging, visuals, and performance data. I worked closely with founders, marketing teams, and creative directors, not just to design campaigns, but to understand why things worked (or didn’t).
That experience taught me something important: no matter how creative the idea, data always tells the real story. And that realization is what slowly shifted my focus from just creating ads to understanding patterns, performance, and behavior through data.
At the same time, I have a bachelor's degree in Mechanical Engineering, which shaped how I think about systems: how small details interact to create big results. Engineering gave me structure and logic; marketing gave me intuition and storytelling. Those two things together are what define the way I work today.
Now, I’ve merged both worlds.
I help people and businesses make sense of their data through tools like SQL and Tableau, creating clear, visual dashboards that actually answer business questions, not just look good. My goal isn’t to drown clients in numbers, but to simplify them into something actionable. Whether it’s sales data, campaign performance, or customer behavior, I love transforming messy spreadsheets into something that finally makes sense.
So, what does all this mean for you as a client?
It means you’re not hiring someone who just executes tasks — you’re hiring someone who sees the full picture. Whether it’s analyzing business data, or structuring a dashboard, I approach every project like an engineer and a storyteller: finding patterns, simplifying complexity, and creating solutions that actually fit people’s lives.
In short, I don’t just build things; I help you understand and improve them.
You can expect clean, structured work that bridges the technical side (queries, organization, metrics) with the visual side (dashboards, insights, clarity).
The foundation for me is always problem-solving. It’s about understanding needs, constraints, and goals, then designing something that feels simple, logical, and human.
If that resonates with you, let’s talk.
Tell me what you’re working on, what’s not making sense yet, or what you’ve been trying to figure out, and I’ll help you turn it into something that works.
