Freelance Data Engineer

I build data platforms.

Open-source stacks, hands-on delivery, no middlemen. Whether you need a quick PoC or a production-ready platform, you work directly with me from the first call to the final handover.

Wojciech Szyba
Data Engineer & Data Platform Engineer / Architect

I've been building data infrastructure for startups and enterprises for several years — everything from single-developer pipelines to platforms processing millions of events a day. My focus is the modern open-source data stack: ingestion, orchestration, transformation, warehousing, and BI. I work hands-on, end-to-end. No account managers, no junior hand-offs — the person you speak to is the person who writes the code.

What I do

Services

01

Platform Architecture

I review your requirements and design an end-to-end data platform right-sized for your team and data volumes. You get a technology recommendation, a component map, and a realistic delivery plan — not a 50-slide deck.

02

PoC & SPIKE Delivery

Time-boxed proofs-of-concept to validate your technology choices before committing to a full build. Typical turnaround: 1–2 weeks. You walk away with working code and a clear go/no-go recommendation.

03

Data Pipeline Development

End-to-end pipeline builds: ingestion, transformation, quality checks, and scheduling. Production-quality Python with tests, documentation, and runbooks included. Ready for your team to own and extend.

04

Migration & Modernisation

Move from legacy ETL, monolithic warehouses, or proprietary cloud services to a modern open-source stack. I handle the migration plan, the data validation, and the cutover — with minimal disruption to your team.

05

Managed VPS Setup

I deploy and configure a complete data platform on a VPS of your choice — your selected tools pre-installed, secured, and monitored — then hand you the keys with full documentation. You're ready to work with data before your coffee gets cold.

06

Training & Enablement

Hands-on workshops covering dbt, Dagster, Airflow, and more — run on your actual codebase, not toy examples. Tailored to your team's level, from first-timers to engineers who just need to go deeper on one tool.

07

Ongoing Support

Monthly retainers covering platform health checks, dependency upgrades, incident response, and roadmap guidance. A known expert on call — without the overhead of a full-time hire.

Process

How we work together

💬

1 — Discovery

A free 30-minute call to understand your data situation, goals, and timeline. No obligation. I'll tell you honestly if I'm not the right fit for your project.

📄

2 — Proposal

A short written proposal: scope, deliverables, timeline, and a fixed price or day-rate estimate. No surprise invoices, no scope creep without agreement.

🚀

3 — Delivery

Async-first with regular check-ins. All code is yours, all infrastructure is yours. I hand over complete documentation and a knowledge transfer session when we're done.
