Hire the Best SQL Consultants in Los Angeles, CA

Most data consultancies fall into one of two camps: strategy firms that hand you a slide deck and walk away, or implementation shops that sit around waiting for you to tell them exactly what to build. Neither works if you're a mid-market company with zero to two data hires. At Data-Sleek, we own the full path from data strategy through AI enablement so you don't have to hire a team to do it well. You shouldn't have to hire a Head of Data just to start. My name is Franck Leveneur. 𝗜 𝗯𝗿𝗶𝗻𝗴 𝟯𝟬+ 𝘆𝗲𝗮𝗿𝘀 𝗼𝗳 𝗵𝗮𝗻𝗱𝘀-𝗼𝗻 𝗱𝗮𝘁𝗮𝗯𝗮𝘀𝗲 𝗮𝗿𝗰𝗵𝗶𝘁𝗲𝗰𝘁𝘂𝗿𝗲 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲.

I'm a GIS analyst and cartographer with 8+ years of experience translating complex environmental, social, and operational data into maps and dashboards that actually get used. I've built interactive Tableau and ArcGIS Online tools for nonprofit disaster response, developed climate visualizations for international NGOs, and mentored students at Columbia University's School of Professional Studies and Climate School. My work has been featured at the Data Visualization Society's Outlier Conference. I work best with organizations where the data matters - environmental nonprofits, sustainability initiatives, climate advocacy groups, public agencies, and mission-driven teams.

My approach is equity-focused, collaborative, and delivery-oriented. I'll ask the right questions upfront so the final product fits your audience, not just your dataset.

I am an expert Data & Analytics Consultant with nearly 10 years of experience delivering high-impact analytics & AI solutions that have moved the needle for 50+ clients across a multitude of industries ranging from Fortune 100 corporations to Series A startups. Data is the most underused asset most companies have - the answers to their biggest questions are usually already sitting in their systems, just buried, scattered, or stuck in reports nobody reads. My job is to surface those answers and make them useful. • Data Strategy — I help you decide what to capture, how it should be modeled, and how to consolidate scattered sources into a single source of truth. Clean, well-structured inputs are what separate dashboards people ignore from dashboards people run their business on. • Analytics & Visualization — I've delivered 100+ dashboards to 50+ clients, turning complex datasets into clear views that answer real business questions. Power BI, Tableau, Looker, Quick Sight & more. • AI Strategy — I help clients move past standard reporting into predictive and prescriptive analytics: where AI actually creates value, what's realistic versus overhyped, and how to put it to work so your data tells you what's coming, not just what already happened. Across all three, my goal is to be a real partner on your hardest problems, not just hand off a file and leave.
