Bridging the gap between reliable industrial machinery and modern data infrastructure. I am a Senior Automation Engineer with a background in Mechanical Engineering. My focus is on delivering complete, end-to-end solutions—from the logic running on the factory floor to the dashboard in the cloud. I believe that successful automation isn't just about writing code; it's about understanding the physical process, respecting the hardware, and building systems that are safe and easy for your team to maintain long-term. 🤝 How I Can Help Your Team Holistic Approach: I combine traditional PLC reliability with modern software practices. Whether it's commissioning a new machine or building a data pipeline, I look at the whole picture. Collaboration First: I work well with on-site technicians and IT departments alike. I document everything clearly so you maintain full ownership of your systems. Reliability: My goal is to build systems that run quietly in the background, minimizing downtime and support calls. 🛠️ Core Services 1. PLC & HMI Programming Platforms: Siemens (TIA Portal), Mitsubishi (GX Works), Allen-Bradley, and WAGO. Logic: Structured, well-commented code following IEC 61131-3 standards. Interfaces: Designing intuitive, user-friendly HMIs (Weintek, Siemens, FactoryTalk) that simplify operations for plant staff. 2. IIoT & Data Integration Connectivity: Integrating industrial assets with the Cloud (AWS, Azure) using MQTT, Sparkplug B, and Modbus. Gateways: Configuring robust Edge Gateways (Raspberry Pi, OnLogic, Arduino Opta) to buffer and secure your data. Visualization: Creating clear, actionable dashboards using platforms like Ignition, ThingsBoard, or FUXA. 🏆 Proven Experience Hybrid Control System: Architected a concrete curing controller that has operated 24/7 for over 18 months, ensuring continuous production even during internet outages. Data Center Modernization: Developed a Python-based Gateway to integrate legacy power units with a modern SCADA system, improving data visibility and response times. Safety & Retrofit: Successfully updated legacy machinery logic to meet modern safety standards, working closely with the client to minimize production impact. Ready to start? If you are looking for a reliable partner to help you automate or digitize your operations, I’d love to hear about your project.

With 4 years of experience in IT infrastructure and technical support, I developed a strong foundation in problem-solving, system monitoring, and incident management. Now I'm applying that analytical mindset to data analysis and business intelligence—helping businesses make sense of their numbers. What I offer: Data cleaning & organization – I turn messy Excel sheets, CSVs, and databases into structured, analysis-ready formats. SQL queries – Need specific data? I write precise queries to extract exactly what you're looking for. Dashboards in Power BI & Tableau – I create clear, interactive visuals so you can track sales, customers, and trends at a glance. Automation with Python – I build scripts that handle repetitive reporting, saving you time and reducing errors. Tools I work with: Python (Pandas, NumPy), SQL (SQL Server, MySQL, PostgreSQL), Power BI, Tableau, Excel. A recent example: I built an automated Power BI dashboard for an e-commerce client that tracks sales by region and top products. What used to take them hours of manual work now updates automatically—saving them over 5 hours per week. I'm relatively new to Upwork, but I bring years of real-world experience, clear communication, and a commitment to delivering quality work. If you're looking for someone reliable who genuinely cares about your project, let's talk.

I help businesses save time and make better decisions — by automating repetitive workflows and turning messy data into clear, useful insights. I work with Python, Excel/VBA, SQL, and Power BI to build things that actually get used: scripts that run automatically, spreadsheets that don't break, and reports that make sense to non-technical people. What I can do for you: 🔧 Automation • Python scripts for file processing, PDF extraction, data transformation • Excel/VBA macros to replace manual, repetitive tasks • Telegram/Discord bots for notifications and commands • Workflow automation connecting spreadsheets, APIs, and databases 📊 Data Analysis • Data cleaning: duplicates, mixed formats, missing values, cross-sheet lookups • Dashboards and reports in Power BI, Excel, or Python (Plotly/Streamlit) • SQL queries and database analysis • Trend analysis and summaries ready for decision-making A bit about my background: I work in hospital IT in Argentina, where I automate internal workflows and manage real-world messy data every day — staff databases, survey exports, cross-reference sheets. I also develop Python desktop tools commercially under my own brand. I'm currently completing a degree in Data Science at Universidad Siglo 21. I'm straightforward to work with: I ask the right questions upfront, deliver on time, and tell you honestly if something isn't feasible. Feel free to message me — I'm happy to take a look at your project before you commit.
