Technical Documentation by an Engineer
Documentation created by someone who has actually designed, built, and troubleshot products. 26 years of manufacturing gives you technically accurate docs — not polished writing from someone who has never held a wrench.
26 Years Manufacturing DocumentationISO/ASME/DIN StandardsEngineering + Technical Writing
What You Get
The Challenge
Your product needs documentation — but technical writers create polished text without understanding how things actually work. Engineers create accurate but unreadable docs. You need someone who is both: an engineer who can write clearly.
My Approach
With 26 years creating manufacturing documentation at Mann+Hummel, I deliver docs that are both technically accurate and clearly written. I've created assembly instructions for membrane modules, operation manuals for lab equipment, and manufacturing drawing packages for production. My docs work because they come from hands-on experience.
The Outcome
Documentation that production teams actually use. Manufacturing drawings with proper GD&T. Assembly instructions that prevent errors. Manuals that reduce service calls. ISO/ASME/DIN compliant.
What You Receive
Comprehensive deliverables package
- 2D Manufacturing DrawingsWith GD&T per ASME Y14.5, BOM, notes
- Assembly InstructionsStep-by-step with photos/renders, tool lists, safety notes
- Operation & Maintenance ManualsComprehensive user documentation
- Technical SpecificationsProduct specs, data sheets, certification docs
Production Ready Standards
How It Works
1
Define Scope & Standards
What documentation do you need? Who is the target audience? What standards must be followed? I review existing materials and define the documentation plan.
2
I Create with Engineering Knowledge
Documentation created by an engineer who understands your product. From CAD-extracted drawings to equipment manuals — technically accurate because I've built similar products.
3
Review & Deliver
Internal technical review, your feedback, 2 revision rounds included. Delivered in required formats: PDF, native CAD, editable documents. Source files provided.

Proof from My Career
90% Lab Documentation
Complete R&D Facility Documentation
Created documentation for 90% of all lab and pilot equipment at international R&D facility. Test protocols, operating procedures, maintenance manuals, and equipment specifications — all to DIN/ISO standards.
Lab DocumentationProduction-Ready Packages
MBR Module Documentation
Complete manufacturing documentation for MBR module family: assembly instructions, BOM, quality control procedures, and inspection checklists. Documentation enabled 50% cost-reduced design to go into series production.
Manufacturing DocsPatent Documentation
2 Filed Patent Applications
Prepared technical descriptions, claims, and supporting drawings for 2 patent applications in filtration technology. Clear documentation of novel design features that secured IP protection.
IP DocumentationDocumentation experience from 26 years of manufacturing and R&D
Featured Project
R&D Facility — Complete Technical Documentation
Created the full technical documentation library for an international R&D facility. Covered 90% of all lab test equipment and pilot plants — from initial equipment specifications through operating procedures, maintenance schedules, and safety protocols.
Key Outcomes
- 90% of all lab and pilot equipment fully documented
- Test protocols enabling repeatable experimental results
- Maintenance manuals reducing equipment downtime
- 60% cost savings vs outsourcing documentation to external vendors
