Prajwal D.

I'm a software and electrical automation engineer with over 8 years of experience delivering solutions at the intersection of engineering design and software development. I work with clients across manufacturing, industrial automation, oil & gas, water treatment, food & beverage, and machine-building sectors.
My core strength is combining hands-on electrical design expertise with custom software development — I don't just draft schematics or write code in isolation, I build tools that make engineering teams faster and more accurate.
**What I Do**
*Electrical Design*
- EPLAN Electric P8 — full electrical schematic design, from single-line diagrams to complete control panel documentation
- EPLAN Pro Panel — 3D panel layout, wire routing, and enclosure design
- AutoCAD Electrical — schematic drafting and design documentation
- Standards-compliant design following IEC 60617, IEC 61082, IEC 81346, and NFPA 79
*Automation & Custom Software*
- EPLAN API and C# add-in development — custom plugins that automate repetitive tasks like BOM generation, cable scheduling, and macro management
- AutoCAD scripting and API customization to speed up drafting workflows
- Macro library creation and management (built and maintained libraries of 10,000+ macros)
- Desktop application development in C# / .NET
- Python scripting for data processing, automation pipelines, and reporting
*Data Science*
- Data cleaning, processing, and analysis using Python
- Building automated data pipelines to support engineering and business workflows
- Custom reporting and dashboard tools
**Why Work With Me**
Most freelancers can either design electrical systems or write software — I do both. That means if you need a schematic designed AND the process behind it automated, I can handle the entire scope without you needing to coordinate between two different specialists. I understand the engineering problem from the inside, so the tools I build actually solve the right problem, not just a generic one.
I've spent years working directly with engineering teams to identify where manual, repetitive work is costing them time — cable schedule creation, macro placement, BOM cross-checking — and building targeted automation to eliminate that overhead.
**How I Work**
- Clear scoping before starting — I'll ask the right questions upfront so there are no surprises mid-project
- Milestone-based delivery for larger projects, so you have visibility and control throughout
- Direct communication — I respond promptly and flag any blockers early
- Clean, documented code and design files, so your team can maintain and extend the work after delivery
Industries I've Worked With
Manufacturing, oil & gas, water treatment, food & beverage processing, machine building, and general industrial automation.
