Your data is there. It just needs the right engineering to be useful.

I design and implement data pipelines that extract, transform and consolidate information from multiple sources into a reliable, scalable system.

30 minutes free, no commitment

Robust ETL pipelines

I build data flows with orchestration, monitoring and automatic failure recovery. Airflow, dbt, Prefect — the right tool for your case.

Consolidated data

I unify data scattered across multiple systems (APIs, databases, files, SaaS services) into a data warehouse or data lake ready for analysis.

Architecture that scales

I design pipelines that process from thousands to millions of records daily without breaking. Predictable costs, minimal maintenance.

How I work

01

Data audit

I map all data sources, formats, frequencies and dependencies. I identify what you have, what is missing and where the bottlenecks are.

02

Pipeline design

I define the architecture: sources, transformations, destinations, orchestration. I choose the right tools for your volume and complexity.

03

Implementation & monitoring

I build the pipeline, put it into production and configure alerts. You know at all times whether data is flowing or something has failed.

Who this service is for

  • Companies with data scattered across multiple systems that need to consolidate it
  • Analytics teams spending time manually cleaning data
  • Startups that need a data warehouse or data lake from scratch
  • Projects that require complex ETL integrations between external systems

Frequently asked questions

Which orchestration tools do you use?

Airflow, Prefect or dbt depending on the case. I choose the tool that best fits your volume, complexity and team.

Can you work with my cloud data?

Yes. I work with AWS, GCP and Azure. BigQuery, Snowflake, Redshift — I know the main data warehouses.

What happens if a pipeline fails?

I design with automatic recovery, retries and alerts. You know in real time if something fails and the system recovers on its own when possible.

Can you consolidate data from multiple SaaS tools?

Yes. APIs, webhooks, exports — I integrate data from any source into a single centralised system.

I worked with Francesco as backend lead on one of the most technically demanding projects I've been involved in. The stack spanned several very different technologies, and he took ownership of all of them, getting up to speed remarkably fast. What impressed me most was his ability to integrate complex systems on first contact — grasping how unfamiliar pieces fit together and making them work correctly, the first time. That instinct is rare, and it made him the person the team relied on when the hard problems landed (we still rely on him as of now!). I'd gladly work with Francesco again and recommend him to any team that needs a dev who can own complexity rather than be slowed by it.
Federico Magnani CTO, glueglue™
Francesco is a professional who conveys confidence, not only from the point of view of in-depth technical skills but above all thanks to his way of tackling the most complex challenges. I feel confident, in conclusion, in suggesting Francesco as a real added value for any development team.
Mattia Costa CEO, Gitaigo
Francesco is an incredible hardcore worker, efficient and super skilled. He helped my organisation throughout all the development of a industry changer IoT system which required a massive effort on the backend side.
Filippo Quercetti CEO, HubWater
Francesco is an excellent programmer, whose great skills have allowed him to handle a variety of areas with excellent results, especially on the back-end and web development side. He is well suited to teamwork and knows how to respect agreed schedules, even under heavy stress and tight deadlines.
Andrea Rinaldo Principal Application Engineer Manager, Emerson
I strongly recommend Mr. Francesco Antonio Sessa as Back-End Web Developer. During 2016, I had the pleasure to collaborate with Mr. Sessa in the context of various Web Development projects for KCS Media Srls. I was impressed by his capability of capturing and leveraging my personal feedback to the extent of evaluating and reviewing the ongoing services. I also appreciated his capability of smoothly entering and boosting multiSite development, and his very helpful and flexible attitude towards the team. He has many soft skills, a very sharp analytic approach to problem solving, and a natural inclination to exploring new opportunities. Overall, I strongly recommend Mr. Sessa as a skilled as well as trusted professional in Web development and Web maintenance matters.
