Hire the Best Engineering Designers
in the Netherlands

I take IoT products from napkin sketch to factory floor. Not just design, actual production. Most hardware freelancers hand you a schematic and wish you luck. I handle the full journey: requirements, hardware architecture, schematic design, PCB layout, CE/FCC/RED certification, DFM optimization, and factory management through my manufacturing network in Shenzhen. What I bring that's hard to find on this platform: → 10+ years shipping real IoT products build in the largest factories in the world. → Direct relationships with PCB fabricators, PCBA assemblers, and test houses in China. → CE/RED/FCC certification expertise, I know what passes and what gets rejected. → PogoBot: our own production test platform used in active manufacturing lines. → Full product management: I coordinate firmware, mechanical, and supply chain in parallel Tech stack: Nordic nRF9160/nRF5340, ESP32, BLE, LoRaWAN, LTE-M/NB-IoT, Altium, KiCad Based in Delft, Netherlands. Insyght is a full-stack IoT studio: hardware, firmware, industrial design, mobile apps, cloud platforms, and production. One team, concept to certified product on the shelf. Let's talk about your product! 15-minute call, no commitment.

If you have a product idea you want to bring to life, I can help you turn it into something you can eventually hold in your hands. I’m a hands-on Mechanical Engineer with over 9 years of experience developing products from the first sketch all the way to fully functional prototypes. I work across every stage of the design process, including concept development, CAD modeling, manufacturing, testing, and assembly. Over the years, I’ve gained practical experience with a wide range of fabrication methods such as laser cutting, creating precise DXF files, CNC machining, milling, lathe work, and general mechanical assembly. This means you’re not just getting a designer, but someone who understands how a product is actually built and how it needs to function in the real world. Whether you need a clear product concept, detailed 3D models, functional prototypes, or a design refined for production, I can support your project from beginning to end. I can help you move smoothly through the entire development process, from the initial idea to a prototype you can test and hold. From the first conversation to the final result, you will always know where your project stands. If you’re ready to turn your idea from an initial thought into a physical product, I’d be happy to help you take that next step.

Experienced Structural Engineer educated in an extensive field of structures, heavy and light, in various structural materials. I possess a good understanding of today’s market design changes. I reply to technical questions quickly and recognize good engineering opportunities to adjust to existing designs to make them fit for purpose. I'm well-versed in Structural Engineering, Earthquake Engineering, High Rise Structures, and Bridge Engineering. Skilled in most design analysis software such as ETABS, SAFE, SAP2000, CSIBridge, CSICols, TEKLA TEDDS, FORTE, IDEA StatiCa, etc. Ample experience in basic structural engineering and capable of providing highly detailed structural engineering designs, plans, and specifications. Excellent in AutoCAD and have been using it for 16 years now. My basic skills are: • analyzing configurations of the basic structural components of a building or other structure; • calculating the pressures, stresses, and strains that each component, such as a beam or lintel, will experience from other parts of the structure due to human use or environmental pressures such as weather or earthquakes; • considering the strength of various materials, e.g. timber, concrete, steel, and brick, to see how their inclusion may necessitate a change of structural design; • liaising with other designers, including architects, to agree on safe designs and their fit with the aesthetic concept of the construction; • examining structures at risk of collapse and advising how to improve their structural integrity, such as recommending removal or repair of defective parts or rebuilding the entire structure; • making drawings, specifications and computer models of structures for building contractors; • working with geotechnical engineers to investigate ground conditions and analyze results of soil sample and in-situ tests; • liaising with construction contractors to ensure that newly erected buildings are structurally sound; • applying expert knowledge of the forces that act on various structures; • using CAD technology for simulation purposes.

Hi, I'm Osman Ender Kalender, a Naval Architect (MSc) based in the Netherlands with 15+ years of experience in yacht design, commercial vessels, workboats, small craft engineering, and advanced 3D modeling. My background spans Feadship, Damen Schelde Naval Shipyard, Euromarine, Sarp Yachts, and multiple R&D and concept-development roles. I specialize in solving complex marine engineering problems quickly and accurately—whether you need hydrodynamic analysis, stability, 3D vessel development, structural layouts, or professional engineering judgment for design decisions. My work combines naval architecture + 3D visualization + practical shipyard-level engineering, which gives clients a rare combination: beauty + engineering accuracy + production-ready thinking. 🔹 WHAT I DO BEST 1) Small Craft & Yacht Engineering (6–50 m) - Hull design, refinements, hydrodynamic viability - Stability, hydrostatics, trim analysis - Powering prediction & engine sizing - Weight estimation / LCG–VCG assessment - CE/RCD-inspired compliance guidance - Parasailing boats, fast craft, leisure craft, refit engineering 2) Concept-to-Model Development -Starting from a hull, sketch, or GA, I can build a full 3D marine model including: -Structural members (frames, girders, longitudinals) -Decks, bulkheads, superstructure -Machinery spaces & arrangement -Piping fundamentals (routing, logical placement) -Clean Rhino topology suitable for CNC & production -CAD drawings (DWG/2D production sheets) This is ideal for early-stage startups, boat builders, and engineering teams lacking in-house naval architecture support. 3) Fast Engineering Consultancy (48h Sprint) Short, high-impact technical tasks: Hydrodynamic viability check Recommended HP + performance prediction Weight distribution evaluation Safety/rigging/structural recommendations Quick technical memos for investors & founders Pre-survey design review for concept feasibility 🔹 TOOLS & SOFTWARE Rhino 3D (expert) – main modeling tool Maxsurf – stability, hydrostatics, powering PIAS – naval architecture tools AutoCAD – 2D drafting KeyShot / Lumion – photoreal renders Siemens NX / 3DX / Teamcenter – production-level design MS Project / PMI methodology – project planning 🔹 WHAT MAKES ME DIFFERENT? ✔ Engineering-Level Accuracy Most 3D designers are artists. I am an engineer first, ensuring proportions, hydrostatic balance, centerlines, and structure make sense in the real world. ✔ Shipyard-Ready Thinking I’ve worked inside major Dutch yards. I know what is buildable, maintainable, and safe. ✔ Clear Communication & Documentation I can deliver technical notes, short engineering memos, design justifications, and investor-friendly feasibility summaries. ✔ Fast & Iterative My workflow is ideal for clients who need progress quickly: “Share your model → I analyze → we iterate → you get clear answers.” ✔ Global Marine Perspective Hydrodynamics, weight, stability, safety—and the practical realities of operating boats—are core to how I work. 🔹 TYPES OF PROJECTS I DELIVER -3D Development Cargo ships (from hull + GA → full 3D structure) Passenger boats Parasailing vessels RIBs, tenders, chase boats Concept vessels & prototypes -Technical Guidance Stability (intact/damage overview level) Powering & performance Weight distribution plans Safety equipment selection Preliminary structural evaluation Feasibility assessments -Visualization Photorealistic renderings Concept presentation materials Environment renders (river, sea, marina) 🔹 WHO I WORK WITH Boat builders Designers & inventors Startups developing new marine products Shipyards lacking NA support Entrepreneurs validating a concept Training schools, watersports companies RYA/CE consultants needing NA input 🔹 AVAILABILITY I work less than 30 hours/week, but in high-focus blocks, ideal for clients who want fast progress and clear results. Short-term sprints or long-term recurring support available. If your project involves water, structure, performance, or the real-world behavior of marine craft — I can help. Let’s build something seaworthy together. Send your hull, 3D model, GA, or even a sketch — and I’ll take it from there. — Osman Ender Kalender Naval Architect, MSc
