Python Temporal Data Research Experiments - GERMANY ONLY

Python Research Developer – Temporal Data Reconciliation Experiments (Germany Only)

Project Type: Fixed Price

Budget: €100–€200 (negotiable depending on experience and proposed scope)

Project Period: 15–31 December 2026

Location: Germany only – registered businesses or self-employed professionals

Project Description

We are seeking a Germany-based Python developer or technical researcher to assist with a short-term experimental software research project involving temporal data processing and incremental state reconciliation.

The project investigates the behaviour of computational systems when historical events are received, corrected or processed asynchronously.

The commissioning company will provide the research objectives, initial hypotheses and experimental requirements.

The contractor will be responsible for implementing and executing a defined set of Python experiments and delivering reproducible technical evidence.

Scope of Work

1. Develop Python scripts implementing specified temporal data processing and reconciliation scenarios.
2. Generate structured JSON test fixtures containing timestamps, event sequences, delayed updates and historical corrections.
3. Implement automated tests, including property-based testing where appropriate.
4. Execute the experiments and record actual system behaviour under different test conditions.
5. Capture original execution logs, including errors, failed tests and unexpected outcomes.
6. Identify and report any implementation limitations or unexpected technical behaviour encountered during testing.
7. Deliver all source code, JSON fixtures, test scripts, execution logs and a brief technical summary.

The experiments should be reproducible and should preserve both successful and unsuccessful results.

Required Skills

- Python 3
- JSON data processing
- Automated testing (pytest preferred)
- Timestamped and event-driven data processing
- Familiarity with asynchronous systems, temporal databases or state reconciliation is advantageous.

Mandatory Contractor Eligibility

Applicants must be genuinely established and carrying on business in Germany.**

Applicants must:

- Be based in Germany and perform the contracted work in Germany.
- Operate through a registered German company or as a self-employed professional (*Freiberufler* or *Einzelunternehmer*).
- Provide their registered business name or full legal business name.
- Provide a German business registration identifier, where applicable, such as a Handelsregister number, Gewerbeanmeldung details or German tax/VAT identification number.
- Must be able to issue a valid invoice in EUR to a German UG upon completion of the agreed work, no later than 31 December 2026.
- Confirm their availability between 15 and 31 December 2026.

Freelancers without a Handelsregister number may still apply if they are legitimately self-employed in Germany and can provide appropriate evidence of their business status.

Sensitive tax identification details may be verified privately after shortlisting rather than posted publicly.

Deliverables

- Python source files
- Timestamped JSON test datasets
- Automated test scripts
- Original experiment execution logs
- Short technical findings report
- Instructions to reproduce the experiments

Application Requirements

Please include:

1. Your experience with Python and automated testing.
2. Relevant experience with temporal data, event processing or asynchronous systems.
3. Confirmation that you are established and will perform the work in Germany.
4. Your German business type and the registration evidence you can provide upon selection.
5. Your proposed fixed-price quotation.
6. Your availability during 15–31 December 2026.

This is a short, fixed-price technical research assignment with the possibility of further experimental work if justified by the findings.

Future opportunities will be announced in 2027.
