I help companies turn scattered data into automated, decision-ready systems — dashboards that update themselves, pipelines that don't break at 2am, and cloud (Bigquery, Fabric) bills that don't spiral. 5+ years specializing in Power BI (advanced DAX, M language), working across both major cloud ecosystems: BigQuery/GCP and Microsoft Fabric/Azure (Lakehouse, notebooks, Data Factory pipelines, Dataflows Gen2, capacity management). I've led a full SQL Server → Fabric Lakehouse migration end-to-end, and manage Fabric capacity governance for ongoing Power BI delivery — most BI freelancers work in one cloud ecosystem; I work comfortably in both. I also build Python automation (ETL/ELT, Cloud Run/Cloud Functions), GA4-to-BigQuery integrations, and AI-driven solutions (WhatsApp voicebots via ElevenLabs). — for clients who want automation beyond dashboards. Industries: Logistics, Finance, Plastic Manufacturing, HR, Marketing, E-commerce, Call Centers, Tourism What I typically deliver: ✔ End-to-end BI systems — from raw data (SQL Server, BigQuery, Fabric Lakehouse, APIs) to automated Power BI dashboards ✔ Microsoft Fabric implementation — Lakehouse/Warehouse architecture, Dataflows Gen2, pipelines, notebooks, and capacity (F-SKU) governance to control cost ✔ GA4 → BigQuery integrations, with clean, reliable data modeling ✔ Cloud cost optimization (FinOps) — on BigQuery (partitioning/clustering) and Fabric (capacity sizing/monitoring) alike ✔ DAX/M optimization for slow or bloated models (VertiPaq, performance tuning) ✔ Python-based data pipelines and reporting automation ✔ AI-powered automation for support, sales, or ops workflows I work both as an individual contractor and through Rumi Data & Tech, a data/tech consultancy I founded in Peru. For larger or multi-disciplinary projects — data engineering + BI + fullstack (React/Node) + AI — I can bring in a small specialized team under Rumi, so you get one point of contact but more bandwidth. Happy to scope either a short-term fix or a long-term retained engagement, whichever fits. We can be partners and develop your business with data ! If your BigQuery bill is a mystery, your Fabric capacity keeps throttling, your GA4 numbers don't match your dashboard, or your reports are slow to trust — that's usually the same underlying problem. Let's talk about what's actually going on underneath it.

I’m an Industrial Designer and 3D modeling expert with years of experience turning ideas into products that connect with customers. I specialize in product design, packaging, jewelry, furniture, and photorealistic renders that elevate brands and make concepts feel real. My work has helped brands present concepts, impress clients, and move seamlessly from sketch to production. I have strong experience in Rhinoceros (and Grasshopper), Fusion 360 (including its Freeform tools), and Blender, which I use for ultrarealistic product renders and also for sculpting complex, organic meshes. Here’s How I Can Help You: I can transform your sketch, reference, or idea into a precise 3D CAD model ready for prototyping or manufacturing, or create photorealistic renders that communicate your product’s value for marketing and investors. ✔ 3D modeling for packaging, jewelry, furniture and more! ✔ Product rendering for marketing, e-commerce, and social media. ✔ CAD files for 3D printing, CNC, or mass production. ✔ Creative input to make your product stand out while staying practical. What Makes Me Different? Most freelancers either do CAD modeling or renders. I do both, meaning you get factory-ready 3D models and photorealistic renders from one person. I combine technical accuracy with design sense, so your product doesn’t just look good, it can actually be made. ✔ Clear communication: I ask the right questions and keep you updated. ✔ Flexibility: I adapt to early concepts or detailed technical specs. ✔ Consistency: Every project receives the same attention to detail. If you are ready to: ✔ Turn your idea into a manufacturable CAD model. ✔ Get photorealistic renders that make your product shine. ✔ Work with someone who understands a wide range of product design needs, from packaging and jewelry to electronics, accessories, furniture, and beyond. ✔ Collaborate with a designer who is both a 3D modeling expert and a product rendering expert. ➡️ Send me a message and let’s bring your product to life.

🏆Do you want to design a freezing system? Or air condition a room?🏆 Hello! I'm Javier Sánchez, a Mechanical Engineer with 16 years of solid experience in the design and optimization of industrial refrigeration and HVAC (heating, ventilation, and air conditioning) systems. I have had the privilege of working in various industries: food, beverages, agribusiness, and fishing, among others. This background has given me great flexibility and broad judgment to solve the unique challenges each project presents, from conception to implementation. Do you need to design a complex freezing system or efficiently air-condition an industrial space? I am here to help you. 🌟 Design of Ultra-Low Temperature Systems (-95°C / -139°F) 🌟 My experience focuses on designing 2 and 3-stage cascade systems to achieve ultra-low temperatures, using refrigerants such as R-23, R508B, R507, R134A, R404. Project deliverables: ✅ Thermal load balance. ✅ Step-by-step installation guide. ✅ Pipe calculation report. ✅ Control logic. ✅ Material takeoff. ✅ Preventive maintenance plan. Drawings and modeling: ✅ 3D design in SolidWorks. ✅ Piping drawings. ✅ Heat exchanger design in Aspen Hysys, Aspen EDR, and HTRI. 🌟 Refrigeration System Design (Refrigerants: Ammonia, Freon, CO2) 🌟 ✅ P&ID design for cooling systems. ✅ Heat pump design. ✅ Freezing and preservation chambers (cold storage). ✅ RSW (Refrigerated Sea Water) system design for fish unloading. ✅ Ammonia freezing plant design. ✅ Optimal selection of heat exchangers (including plate heat exchangers), chillers, and other equipment. ✅ Chilled water systems for process. ✅ Selection of glycol (chilled water) recirculation pumps. ✅ Air conditioning of process rooms. 🌟 Services Offered in HVAC 🌟 ✅ HVAC system design for residential buildings, condominiums, shopping centers, and more. ✅ Equipment selection. ✅ Duct and pipe sizing. ✅ Grille and diffuser selection. ✅ Mechanical ventilation system design. ✅ Extractor and injector calculation. ✅ Technical file for license approval. ✅ Constant pressure systems for process rooms or stairs. ✅ Dust extraction systems. 💡 Additional Technical Support Areas 💡 Besides complete designs, I can offer specialized technical support in: 1. Computational Fluid Dynamics (CFD) modeling using Ansys Fluent. 2. Heat exchanger design with Aspen Hysys, EDR, or HTRI. 3. Advanced and detailed 3D modeling in SolidWorks. ✨ Why Choose Me Over Other Freelancers? ✨ The added value I offer goes beyond just design on paper. I have the judgment and practical experience from having built industrial plants from scratch, implementing and coordinating disciplines such as civil, mechanical, piping, refrigeration, structural, and electrical. This comprehensive vision allows me to anticipate potential interferences and harmonize my design efficiently with the rest of the project, avoiding setbacks and cost overruns during the construction phase. ✨ Remember: ✨ Modifying a drawing has minimal cost. Modifying what has already been built directly impacts the project's budget and schedule, besides causing inconvenience. Therefore, it is essential to choose correctly the person who will carry out your design. Good design engineering is the best investment! I enjoy applying my creativity, experience, and knowledge to provide the best solutions for my clients. I am drawn to complex and challenging applications, and my approach to tackling difficult jobs prepares me for almost any task within my areas of expertise. Thank you for visiting my profile! 😁 I look forward to hearing from you soon and collaborating on your next project. 🔜 #mechanicalengineering #hvac #refrigeration #ammonia #freon #co2 #solidworks #aspenhysys #aspenedr #htri #ansysfluent #fluent #cfd #autocad #coolselector #heattransfer #heatexchanger #plateheatexchanger #industrialdesign #optimization #energyefficiency #freelancer #upwork #coldstorage #chamberstorage #chiller #modeling
