Senior Data & Analytics · Freelance
I’m Simon Sangla — 15 years turning messy data into decisions, as Senior Lead Analyst at TripAdvisor and across senior analyst and BI-consulting roles (MSc, Université Paris 1 Panthéon-Sorbonne). Now independent, I pair that depth with a modern Snowflake + AI stack and ship the dashboards, models and tools your team actually uses in days, not quarters. Every service below is backed by something I’ve already built and put online, solo.
What I do for hire
Lead service
From raw warehouse tables to a board-ready readout — the core of my consulting work.
You get: a working dashboard or model, the queries behind it, and a short readout of what the numbers mean — not a slide deck of jargon.

Zero-infra, single-file tools your team opens in a browser — no logins, no servers, no maintenance bill.
You get: a finished tool that runs anywhere, with the source — yours to keep, fork and extend.

Transparent, rubric-driven scoring and content generation — the same shape as my AI-training evaluation work.
You get: a scoring tool or evaluation pack with a documented, defensible rubric behind it.

How I work
01
A short call or email thread to pin down exactly what you need and what done looks like. Fixed scope, fixed price — no open-ended hourly drift.
02
I build at lab cadence — you see a working version fast, not a status update three weeks later. Most tools land in a day or two.
03
You get the working thing and its source. One round of tweaks included; ongoing work by the project, never a retainer you forget you’re paying.
Why me
Tell me the problem in a sentence or two and I’ll tell you whether I’m the right person and roughly what it takes. No pitch, no obligation.
