Nicola Simboli

Senior / Staff Analytics Engineer (Snowflake · AWS)

I design and own scalable analytics foundations that turn raw data into trusted, decision-ready insights. From ingestion to curated datasets, semantic layers and KPI governance, I build systems that scale with product, teams and business complexity.


About

With 15+ years of experience across SaaS, enterprise and consulting environments, I help product-led, remote-first companies build analytics systems that people actually trust and use. My work focuses on analytics engineering, platform ownership and metric reliability, enabling consistent decision-making across product and business teams.

Me

Experience snapshot

I’ve held senior analytics engineering and consulting roles at companies including Docebo, Methode, Ascopiave and CEVA Logistics, working across SaaS and enterprise environments.

  • 15+ years in BI, analytics and analytics engineering
  • SaaS, enterprise and consulting contexts
  • High-scale Snowflake environments on AWS
  • Platform ownership in distributed, remote-first teams
  • Strong focus on reliability, performance and adoption

I’m less interested in trends and buzzwords, and more interested in systems that still work two years later.

Technology

  • Snowflake
  • AWS (S3, Lambda, EventBridge, CloudWatch, ECR)
  • Advanced SQL
  • Python
  • Tableau (Cloud & Server)
  • Looker
  • Git
  • Terraform
  • Docker

Tools matter, but clear ownership, governance and trust matter more.

What I do

  • Owning analytics engineering for product and business analytics
  • Designing curated datasets and dimensional models on Snowflake
  • Defining and enforcing KPI governance and metric consistency
  • Building semantic layers that enable reliable self-serve analytics
  • Scaling analytics platforms used by hundreds to thousands of users
  • Acting as a bridge between product, engineering and business stakeholders

What I avoid

  • Dashboard-only or reporting-only work without ownership
  • Metrics defined without governance, documentation or accountability
  • Platform changes without considering scale, adoption and impact
  • Analytics work disconnected from product and business decision-making

My approach

I approach analytics engineering as a long-term system, not a collection of dashboards or isolated pipelines. In practice, this means:

  • Prioritizing ownership over delivery
  • Designing datasets and metrics that remain reliable as teams grow
  • Treating KPI definitions and semantic layers as products, not documentation
  • Balancing self-serve enablement with governance, performance and cost control
  • Making trade-offs, documenting decisions and aligning stakeholders in remote-first environments

What I care about

I care about analytics that:

  • Is trusted by stakeholders
  • Scales without constant rework
  • Enables autonomy without chaos
  • Supports real decisions, not just reporting

Who I work well with

I tend to work best with:

  • Product-led companies scaling their analytics foundations
  • Teams that value clear ownership and shared standards
  • Organizations transitioning from “BI reporting” to analytics as infrastructure
  • Remote-first companies operating across Europe or globally

GeoClassy Python package

The geoClassy Python package was developed from the need of using GeoJSON files with OpenStreetMap data to classify points which GPS coordinates are known. Using the GeoJSON format as input, the package can also be used with files from sources different from OpenStreetMap.

Examples of use:

  • - find the neighborhood of the city with most AirBnB beds;
  • - classification of customers by key account area of competence;
  • - filter of road accidents in a certain province;
  • - assessment of the air quality for a specific Municipality;
  • - list of cities affected by the passage of a hurricane.

Amazon best deals about Lego and products for pets

The project is based on reading prices from Amazon e-commerce platforms and to publish the greatest deals to segmented user groups (on Telegram channels and Facebook pages). At this moment there are three groups: users passionate by Lego bricks, owners of cats, owners of dogs. The tool is one hundred percent written in Python 3.x/MySQL and uses several APIs (including Product Advertising API, Telegram API, and Facebook Graph API).

Delivery 74

The website provided a list of shipping fees from several parcel companies in Italy, based on the shipping location, the delivery location, the dimensions, and the weight of the box. Using this platform, casual shipping users could choose the cheapest solution based on the performance level described. I developed every part of the website (mainly in PHP, HTML, MySQL and jQuery) and also project the User Interface with complex controls (for example autocomplete of locations based on geolocation APIs). The project ended mostly because parcel services didn't have affiliation programs so it was very difficult to monetize the user's experiences.

Let’s talk

I work on designing and evolving analytics foundations in product-led, data-heavy environments. My focus is on building systems that scale over time: trusted datasets, clear metric definitions, and analytics platforms teams can actually rely on.

Most of the analytics work I’m brought into starts when one of these things breaks:

  • Metrics don’t match across teams and no one trusts the numbers
  • Product analytics works at small scale but collapses as usage grows
  • Self-serve exists in theory, but governance and ownership don’t
  • Analytics platforms become expensive, slow, or politically fragile

This usually happens when analytics grows faster than its foundations.

I tend to work best in contexts where analytics is treated as infrastructure rather than reporting, and where senior ownership, long-term thinking and close collaboration with Product and business stakeholders are expected.

If you’re already questioning whether your current analytics setup will still work a year from now, we should probably talk.
