Prozorro.sale

We`ve developed a system that brings transparency and prevents corruption in procurement processes.
Prozorro.sale is the official portal and Sale of state and communal property belonging to liquidated banks, non-performing loans (NPLs), and lease rights.

It’s a Deposit Guarantee Fund (DGF) system that organizes the sale of property (assets) belonging to insolvent or liquidated banks and the sale of non-performing loans. Such assets include collateralized property (like household appliances, cars, buildings, land, and lots) and loans (individuals` receivables set and legal entities).

According to the Ukrainian laws, such assets are sold through electronic exchanges based on rules similar to those of the EU or the US. In order to ensure transparent, effective, and fair sale procedures DGF decided to apply the same software that is already proven to be effective in the Prozorro system.

Challenges:
– Components are scattered across many repositories, some of which are used in the procurement system;
– Difficulties in understanding which versions of which components are deployed in a particular environment at the moment;
– Violation of encapsulation of services and components, versions of dependencies were defined not by service, and in the course of deployment:
– Manual assembly of services, which leads to an additional workload on the DevOps team and an increased probability of human error;
-The absence of versions of the code services and components;

Solutions:
– Microservice architecture using Kubernetes, Docker, Helm, and GitLab CI for full automation and scalability;
– Fault-tolerant infrastructure using MongoDB and stateless services;
– A centralized database (CDB) system modeled like a stock exchange: users access tenders through any of 50+ marketplaces, ensuring equality and eliminating monopolies;
– Transparent reverse auction system, preserving anonymity during bidding and full disclosure post-auction;
– Tech stack: Aiohttp, MongoDB, Elasticsearch, Prometheus, Grafana, Python, GitLab CI, Helm, GitLab, Swagger, Kubernetes, and Docker;

Results:
– $890 million revenue generated;
– 245,000+ lots created;
– 15,000+ participants;
– 50 marketplaces connected;
– Enabled Ukraine’s Small Privatization reform;
– Established an independent Supervisory Board;

Award-Winning Impact:
In 2021, Prozorro.sale won the Open Government Partnership Global Summit Impact Award in Seoul, recognized as the world’s best public sector transparency project. Competing against 17 countries, the platform stood out for driving real societal change.

Prozorro.sale is more than a platform. It`s a powerful symbol of digital transparency and trust in government. A proven model of how smart tech can build better democracies.
