I’m a Python backend engineer specializing in PDF & document processing systems, internal data pipelines, and workflow automation used in real production environments.
Most of my work focuses on turning unstructured inputs — PDFs, spreadsheets, emails, reports — into reliable, structured data that teams can trust for operations, reporting, and decision-making.
🟢 What I typically build:
- PDF parsing & document ingestion pipelines;
- data extraction, validation, and normalization systems;
- internal backend services & APIs;
- workflow automation for ops, finance, and reporting;
- replacing manual Excel / email-based processes with Python systems.
🟢 Problems I help solve:
- PDFs / CSV / XLS / TXT and other types of documents that are hard to process at scale;
- manual data handling that causes errors and delays;
- automations that break on real-world inputs;
- internal tools that need reliability, logging, and maintainability.
🟢 Tech stack:
- Python (production backend services & data pipelines);
- REST APIs & webhooks;
- FastAPI / Django / Falcon;
- Cloud: AWS & GCP;
- Containers: Docker;
- Databases & storage systems;
- Observability, logging, error handling.
🟢 How I work:
- senior-level backend & systems mindset;
- clear scoping and realistic timelines;
- production-ready code with error handling and observability;
- direct communication — no handoff to juniors or agencies;
I’ve built and maintained systems handling real production data, not demos or prototypes.
If you need a backend or document-processing system that must work reliably in production, feel free to reach out with your use case.
