I’m looking for a data-savvy partner who can turn my raw numbers into clear, actionable guidance that streamlines our internal processes. I have the data ready to go; what I need is a thorough analysis that highlights inefficiencies, pinpoints bottlenecks, and shows exactly where we can save time or money. You’ll be free to work in the environment you’re most comfortable with—Python (pandas, NumPy), SQL, R, or even a well-structured Excel or Power BI setup—as long as the final output is easy for my team to understand and replicate. A concise summary of your methodology, all cleaned datasets, and a visual or written report of the key insights will round out the hand-off. If you’ve previously optimized workflows or operations through data-driven insi...

I’m arranging a short-term training program for an engineering college and need a freelance technical trainer who can deliver an engaging Java Data Structures & Algorithms series to intermediate-level students. The cohort has already mastered core Java syntax; what they now need is clear guidance through data structures, algorithmic thinking, and hands-on problem-solving strategies that prepare them for coding interviews and competitive programming. While this round is Java-specific, the college may explore a Python DSA track next semester, so familiarity with both languages is welcome even if not essential right now. Here’s what I’m looking for: • A structured yet flexible curriculum that covers key data structures (arrays, linked lists, stacks, queues, trees...

I want to build a set of AI-driven plugins that plug straight into our LinkedIn connection database and continuously enrich each profile with deeper demographic details and behavioural insights. The core workflow is data updating: whenever a new customer record appears—or an existing one changes—the plugin should trigger, fetch the most relevant external signals, run light machine-learning scoring if needed, and write the additional fields back to our CRM in real time. Scope • Data domain: strictly customer data. The enrichment must cover both demographics (age band, location, income range, etc.) and behavioural patterns (engagement frequency, preferred channels, likelihood to churn). • Automation focus: updating only. Collection pipelines already exist; I just n...

Hello, My name is Víctor and I am looking for a reliable freelancer who can assist me on an ongoing technical project.

I am overhauling our analytics stack so every report and dashboard refreshes automatically, without anyone pressing “run” or “export.” The goal is a fully automated, real-time pipeline that ingests raw data, validates its quality, and surfaces clean metrics directly to our BI layer. Real-time processing is essential, and Google Cloud is our chosen environment. Expect to work primarily with Pub/Sub for event ingestion and Dataflow (or an equivalent managed service you recommend) for streaming transforms. All configuration—service accounts, IAM roles, network rules—needs to be production-ready and documented. Beyond moving bits from A to B, I need genuine process optimisation. Historical bottlenecks must be surfaced through analysis, then eliminated thro...

I need a developer available on-demand (Monday to Friday, 09:00–18:00 CET). The response have to be very very quick. I am looking for someone who can be ready to code when I send a task. Tasks are usually 1–2 hours each, and we will work together through AnyDesk on my computer. Quick response is essential: when I send a task in the chat, I need someone who can start immediately. If not, I will assign it to the next person. This is urgent work and can become a long-term collaboration. Example of tasks: Run a Jenkinsfile and fix issues if necessary. Apply changes related to our CI/CD pipeline. Adapt configurations to a different type of GCP infrastructure (as seen in Jira). General help with Python/GCP/DevOps tasks. Payment: The rate is 10–15 EUR per hour. Important...
