Last position:
Developer at agentic-engineer.online
agentic-engineer.online is my publicly testable live demo and at the same time the platform where I show my work. Originally created as a recruitment trial task, I have since continued to run it as my own demo, learning, and product project — on a Hetzner VPS behind a Cloudflare tunnel, through a multi-stage AI-orchestrated deploy pipeline with snapshot rollback. If a deploy step breaks, the system falls back to the last clean snapshot, the script is adjusted, the test repeated — empirical, test-driven, without hand tuning.
- Technically behind it: Python and FastAPI, an OpenRouter model cascade, SQLite persistence, and Cloudflare edge tuning.
- I am the developer and the strictest customer of my own AI work in one person — what started as a prototype has become a tool I use every day and against which I test my own products.

Last position:
Senior Software Engineer — AI Evaluation & Benchmarks at Diversido
- Provided technical leadership for a 4-engineer team delivering 3 major client platforms in 12 months with microservices architecture and scalability solutions — 100% of scoped majors shipped ahead of schedule vs. planned milestones (baseline: prior releases often slipped 1–2 sprints).

- Drove API development and performance optimization for payment, exchange, and AI services; fail-closed error handling and payload validation reduced integration rework cycles by ~35% vs. the first AI integration pass.
- Applied software testing, testing frameworks, code quality assurance, and code refactoring with continuous integration gates; first-pass PR acceptance improved across the team and production hotfixes on AI adapters dropped noticeably after review standards landed.
- Owned DevOps practices: Docker, GitHub Actions, Jenkins-compatible pipelines, and version control workflows — cut deployment time ~50% vs. pre-automation baseline and stabilized releases across 3 client environments.
- Implemented verifier/oracle-style pass-fail checks in container sandboxes (Harbor/Terminal-Bench aligned); wrote technical documentation so failures cleared in one review cycle.

About the technology
Data format
CSV, short for Comma-Separated Values, is a plain-text format for storing tabular data. Each line represents a record, while separators divide fields. Commas are common, but semicolons, tabs and other delimiters are also used, especially across different business systems and regional settings.
Practical uses
CSV is a common exchange format between business applications, databases and analytical tools. Companies use it when a lightweight, readable file is more useful than a direct system connection.
- Import customer, product and transaction data
- Export reports for finance, operations and analytics
- Prepare files for migrations and bulk updates
- Transfer data between systems without a shared API
Reliable processing
Working with CSV requires more than splitting text at commas. Quoted separators, line breaks inside fields, empty values, character encodings and inconsistent column names can all change the meaning of a record. Strong specialists define parsing rules, preserve data types and test files against real edge cases.
Common tools include Python with pandas, R, SQL import utilities, spreadsheet applications and command-line processors. Larger workflows may connect CSV handling to ETL tools, cloud storage, data warehouses or scheduled automation.
When expertise helps
Freelance expertise is useful when recurring imports fail, files contain inconsistent structures or a migration depends on accurate bulk data. Specialists can also replace fragile spreadsheet routines with repeatable processes and clear validation steps.
- Diagnose encoding, delimiter and quoting problems
- Map columns between legacy and current systems
- Clean duplicates, missing values and invalid formats
- Automate recurring imports, exports and checks
Systems and industries
CSV appears in e-commerce catalogs, customer relationship systems, enterprise resource planning, accounting, logistics and research workflows. It often sits between older software and modern services, where data must move reliably without a direct integration.
In Germany, teams may need to align files from local business processes with international systems and distributed project groups. Clear field definitions, documented assumptions and dependable handovers matter in both remote and on-site collaboration.
Quality signals
A capable CSV professional asks where the file comes from, who consumes it and which fields are authoritative. They inspect samples, define an explicit schema and make failures visible instead of silently dropping records. They also separate one-time cleanup from a process that must run repeatedly.
Look for practical knowledge of encoding, delimiters, quoting, validation, version control and data protection. The strongest deliverables include tested transformations, reconciliation checks, useful logs and documentation that lets another specialist operate the workflow safely.
Frequently asked questions
Quick answers to the questions that come up most around CSV.
CSV is used to exchange tabular data between spreadsheets, databases, business applications and analytics tools. Companies commonly use it for imports, exports, reporting, migrations and bulk updates when a simple file is sufficient.
Comma-Separated Values stores rows and fields as plain text, so it is lightweight and easy to process across systems. Excel supports formatting, formulas and multiple sheets, while JSON represents nested data more naturally; the right choice depends on the structure and receiving system.
A strong CSV specialist should understand SQL, databases, data cleaning and file encodings. Experience with Python, pandas, R, ETL tools, APIs or cloud storage is useful when file handling forms part of a larger data workflow.
The required experience depends on the risk and complexity of the workflow. A simple export may need careful file preparation, while recurring integrations or migrations require proven skills in schema mapping, validation, error handling and reconciliation.
CSV work is often suitable for remote collaboration because files, mappings and test results can be shared securely. On-site sessions can still help when specialists must inspect legacy software, coordinate with operational teams or resolve unclear data ownership.
CSV imports often fail because of the wrong delimiter, character encoding, quoting rules, line endings or column order. Missing values, duplicate records and unexpected date or decimal formats can also create errors when the receiving system applies strict validation.
Ask for a documented schema, representative test files and clear validation results. High-quality CSV work preserves records, reports rejected rows, handles edge cases explicitly and includes repeatable steps rather than relying on manual spreadsheet corrections.
A CSV freelancer should clarify the source and destination systems, delimiter, encoding, expected columns, data volumes and failure-handling rules. They should also confirm whether the task is a one-time cleanup, a scheduled process or part of a wider migration.
The average hourly rate of freelancers in Germany who have used CSV in their recent projects is 94 €, which corresponds to a daily rate of about 752 € based on an 8-hour working day.
