Why sponsoring

I am currently active with the development of psycopg3: initial funding goes directly towards the development and completion of that project.

In the longer term, funding will ensure the maintenance of psycopg2, psycopg3 and other projects.

What I have done

My main area of expertise is between Python and PostgreSQL. The most successful project in that space has surely been Psycopg, which I've been involved with occasionally since its inception, taking on the role of main contributor since 2010 (with development, documentation, testing, web presence) and making it become the de-facto standard adapter.

Aside from Psycopg, I have developed and maintain several other projects, some of which can be considered the industry standard for their task:

There are another number of projects I would like to develop, but I find my time constrained:

  • psycopg3: the successor of psycopg2. The work is in progress!
  • replisome: a framework for flexible replication and messaging for PostgreSQL
  • bromine: a Pythonic wrapper to write Selenium tests with Python idioms.
  • pg_seldump: a tool to extract selective data from PostgreSQL databases in a way more flexible than pg_dump
  • pgaudit: a simple audit solution for PostgreSQL data

What I want to do

I have terminated my full-time employment back in February 2020. I am currently receiving several offers for full-time jobs, however it would be my desire to refuse the call for a stable employment and pursue the development and maintenance of the free-software projects I am responsible for, topping up with contract work when needed.

Some projects of mine are in the need of attention. While I do receive messages and requests about them, it rarely develops into concrete support. Receiving sponsorship for these projects would be an excellent incentive to address their shortcomings, bitrot, and develop new features.


For a practical use of the generosity space, please find some monthly donation suggestions in convenient powers of two.

Because not everyone is keen on recurring support, one-off contributions are welcome too. In terms of perks, they will be considered as 2 levels below (that's $128 for a t-shirt, but your average socialite would still surely pay more).

On the other hand, I appreciate the reliability of long term support: if you are a long term supporter, you will reach the perks of the above tiers, but one tier later (that's $2 for a t-shirt if you can wait 5 years).
