Gilad G.
Last position:
European Strategy Atlas – Independent Analytics & Decision-Support Project at Independent Project
Designed and built an end-to-end interactive decision-support application using public European data across 27 EU countries and multiple strategic dimensions. Developed a structured analytical methodology for comparing countries, identifying patterns and trade-offs, and exploring strategic choices rather than presenting static dashboards. Translated complex multidimensional data into guided interactive exploration and learning workflows for non-specialist users. Built the application end-to-end using Python and Streamlit, with AI-assisted development and Git-based version control. Developed the project independently from problem framing and data analysis through methodology, UX logic, implementation and deployment.
Tools: Python, Streamlit, Git, AI-assisted development

About the technology
What Streamlit does
Streamlit is an open-source Python framework for turning data scripts, machine learning models and analytical workflows into interactive web applications. It lets specialists create interfaces with Python rather than building a separate frontend and backend. Companies use it for internal tools, proof-of-concept products, dashboards and model demonstrations.
Apps and use cases
Streamlit is well suited to fast delivery when users need to explore data or test a model through a browser. Typical work includes:
- Building interactive dashboards for business and operations teams
- Creating interfaces for machine learning predictions and natural language workflows
- Presenting data exploration tools to analysts and product teams
- Turning notebooks or Python scripts into shareable applications
Python ecosystem
Strong Streamlit professionals work across the Python data ecosystem. They commonly use pandas, NumPy, Polars, scikit-learn, PyTorch or other model libraries, alongside SQL and cloud data services. They also understand Streamlit components, session state, caching, multipage navigation and secrets management. Git, testing and container tooling help keep applications maintainable.
When to bring in expertise
Companies often seek freelance support when a promising notebook needs a usable interface, an internal dashboard must reach more users, or a data product needs a focused prototype. In Berlin, Streamlit work may support technology, research, finance and industrial teams that combine local collaboration with distributed delivery. Specialists can clarify scope, structure the application and connect it safely to existing data sources.
Production considerations
Streamlit makes iteration quick, but a reliable application still needs thoughtful design. Professionals should address authentication, authorization, data privacy, dependency management, error handling and performance. They may package the app with Docker, deploy it through Streamlit Community Cloud or a cloud provider, and connect monitoring and automated delivery where the use case requires it.
Choosing a strong specialist
Look for evidence of complete Streamlit applications, not only attractive screenshots. A capable specialist can explain data flow, state handling, refresh behavior and deployment choices in plain language. They ask how users work, protect sensitive data and separate exploratory code from reusable application logic. Clear documentation and communication matter when Berlin-based stakeholders work with remote teams.
Frequently asked questions
Before you brief your next project: the most common questions about Streamlit.
Streamlit is used to create interactive browser applications from Python scripts, data workflows and machine learning models. Companies often use it for dashboards, internal tools, prototypes and interfaces that let users run or explore analytical processes.
Streamlit usually offers a simpler path from Python code to a working data app, with less frontend setup. Dash can provide more structured control over complex dashboards, while Gradio is often chosen for focused machine learning or generative AI demos. The right choice depends on interaction complexity, design requirements and production constraints.
A strong Streamlit specialist often also works with Python, pandas, SQL, APIs and cloud services. Experience with machine learning libraries, authentication, Docker, Git and automated deployment is valuable when the application must move beyond a prototype.
The required experience depends on the scope rather than the framework alone. A small internal dashboard may need strong Python and data skills, while a customer-facing application calls for expertise in security, testing, deployment and application structure. Ask candidates to show work with similar data sources and users.
Yes, Streamlit work is well suited to remote collaboration because code, data access and deployments can be managed through shared repositories and cloud environments. Berlin teams should define access rules, communication routines and language expectations early, especially when sensitive company data is involved.
Streamlit can support production use when the application has a suitable scope and is designed carefully. Teams must still plan authentication, permissions, secrets, dependency control, observability and scaling. For highly customized public products, a dedicated frontend may be a better fit.
Review a Streamlit specialist's deployed examples and ask how they handle session state, caching, errors and data refreshes. A quality professional can explain trade-offs, keep business logic organized and make the interface understandable for people who are not data specialists.
Before starting Streamlit work, clarify the target users, data sources, hosting environment and security requirements. It also helps to establish whether the goal is a quick prototype, an internal application or a maintained product, because each calls for a different level of testing and deployment discipline.
