30 USD Data collection system
Data Parsing- Development of a data collection system: Based on collected business requirements and an analysis of target resources, specialists initiate the development of a data collection system. This involves selecting appropriate technologies and tools, designing system architecture, and crafting necessary components and functionality.
- Implementation of data transfer pipelines: Following the development of the data collection system, pipelines or processes for transferring received data to the client are established. This may entail integration with existing client systems or the creation of new data transfer methods such as APIs or file transfers.
- Integration with existing systems (if required): In cases where an existing system is already in place, integration of the developed data collection system with the current infrastructure is undertaken. This ensures seamless operation and compatibility with the client's existing business processes.

20 USD Parsers Estimate
Data ParsingThis service provides a comprehensive approach to analyzing and selecting optimal technologies for implementing a parser (data collection system) tailored to a specific task and target resource. Here is a detailed description:
- Target Resource Exploration: A thorough study of the target web resource slated for parsing is conducted. This encompasses analyzing site structure, available data, formats for information presentation, and access methods.
- Implementation Plan Development: Based on the gathered information, an implementation plan is crafted. This plan determines the appropriate parser and integration method with the target resource. It involves selecting technologies, tools, and scraping methods best suited for the given context.
- Implementation Cost Estimation: Using the implementation plan, the expected cost of the parsing project is assessed. This estimation includes evaluating the time and resources required for parser development, testing, and implementation.
… - Full Parsing Cycle: Upon the customer's decision, specialists commence the parsing project implementation. This process encompasses parser creation, configuration, optimization, as well as performance testing and data quality assessment.

Scope of Tasks (Initial Infrastructure Phase)
Very satisfied with the collaboration. Elizaveta not only completed tasks but also genuinely helped to build the architecture and workflow logic.
I especially liked the ownership approach, code quality, calm communication, and the ability to make technical decisions independently without overengineering.
The work was done very professionally, structured, and with a good understanding of the long-term development direction. We plan to continue the collaboration in the future.

Logging для clinical validation.
Elizaveta quickly understood the complex architecture of the project, proposed the right technical solutions, and successfully implemented the API, regression testing, and logging. It is especially valuable that she thinks systematically, pays attention to stability and reproducibility of results, rather than just "making it work." Communication was easy, all tasks were completed on time and with attention to detail.

Regression / stability check.
Excellent work. The contractor carefully brought the stage to a stable state: the API pipeline was implemented, the aggregation logic was corrected, and regression was added to check stability. The code is structured, and revisions from the review were made quickly and accurately. Communication is at a high level, and deadlines were met. We plan to continue the collaboration.

Phase 7 Website Demo Integration
Laid down by the result.
The project included the integration of an ML pipeline, API, and web UI with deployment on Railway. As a result, we obtained a fully functional end-to-end demo (upload → analysis → result).
The performer demonstrated a good level: independently found and fixed problems, correctly set up deployment, integration, and API. Communication was clear and to the point.
Ready to continue collaboration in the next stages.

Placido Pipeline Iris Detection Root Cause Analysis
Thank you for the completed work — this is a strong result. You approached the task correctly: you found the root cause of the problem (IRIS_NOT_FOUND), carefully corrected the configuration without changing the logic, stabilized the pipeline and brought it to a working state, added a clear structure for results and logging. It is especially valuable that you did not try to "work around" the problem through parameters, but rather understood the cause. Now the pipeline is already providing valid results, and this is a good basis for the next stages.
