SEEKING WORK | Remote | Based in Berlin, Germany

Hi, I'm a freelancer with 8+ years of international experience as a Solution Architect, Data Engineer, and Python Developer, specializing in cloud platforms, scalable data infrastructures, and machine learning solutions.

Recently, I led the implementation of a modern Azure Databricks Data Lakehouse for a Swiss-German manufacturer, delivering a scalable analytics infrastructure with data governance frameworks, CI/CD pipelines, and LLM-powered analytics interfaces. I’ve worked with clients across various industries, delivering end-to-end data solutions.

Freelance projects I can help with:

- Building complete data platforms from scratch, tailored to your needs.

- Enhancing and upgrading legacy data systems for better performance and scalability.

- Establishing robust Databricks environments with proper governance and scalability.

- Developing machine learning and GenAI applications that integrate seamlessly with your data.

- Providing strategic guidance on how to kickstart your data initiatives or MVPs effectively.

Some of the technologies I work with:

Python, Spark, SQL, Terraform, Databricks, Airflow, Docker, MLflow, PyTorch, LangChain, SpaCy, Kafka, Bash, JavaScript, Fivetran, Flask, FastAPI, Power BI.

If you have a data or ML/AI project in mind — or just want to explore possibilities — feel free to reach out. I’d be happy to have a chat!

I'm Sam Bleckley, a full stack engineer with 2 decades of successful outcomes consulting across dozens of industries. I can help with:

- Technical challenges ("We know the feature we want, but we don't have the expertise or the time to get it built")

- Process challenges ("We keep missing deadlines," "We're deploying too many bugs," or "The team has no motivation")

- Product design challenges ("We believe this solves our users' problems, but they aren't using it they way we expect")

I also offer fixed-bid development of small prototypes and MVPs, if you need to prove an idea, or have a new project hit the ground running.

If you're looking for experience in a specific tech stack, here are some of the technologies I'm comfortable using:

```AngularJS, Angular, AWS (S3, Lambda, RDS, &c.), C, CSS, Creative Cloud, Flask, git, Glamor, GCS, HTML, Javascript/ECMAscript, Lisps of many varieties, Next.js, Node, Photoshop, Python, Ruby on Rails, React, Ruby, SASS, SCSS, Svelte, Swift, Typescript, Vue, whatever legacy DSL you've got ```
