Sebastian B.

US Mechanical Engineer | Product Design & DFM Specialist | Prototyping

I bridge the gap between concept and commercial reality. As a US-based Mechanical Engineer with 6+ years of experience, I engineer shop-ready products that work in the real world and in simulation. I help entrepreneurs and US manufacturers eliminate costly fabrication errors, optimize production cycles, and navigate the complex path from napkin sketch to mass production. Why Clients Choose Me Over Offshore Alternatives: US-Based & Compliant: I operate in your time zone and am fully qualified for IP-sensitive projects. Your intellectual property never leaves US jurisdiction, ensuring maximum security. ⚙️ Shop-Floor Fluency: I speak the language of machinists and mold makers. My designs are built with Design for Manufacturing (DFM) at the forefront, ensuring you don't pay for features that can't be machined. 📉 Capital Efficiency: I use advanced simulation (FEA & CFD) to validate designs virtually, reducing the need for expensive physical prototype iterations. My Core Engineering Solutions: 1. Design for Manufacturing (DFM) & Assembly The Goal: Reduce unit cost and tooling complexity. The Process: Rigorous analysis of wall thickness, draft angles, and tolerances (GD&T) for Injection Molding, CNC, and Sheet Metal. I deliver files that machine shops accept without questions. 2. Concept-to-Reality Product Design The Goal: Transform vague ideas into functional products. The Process: Full-lifecycle development using Fusion 360. From complex mechanism design to aesthetic enclosures, I create parametric, editable assemblies ready for future iteration. 3. Risk Mitigation via Simulation (FEA) The Goal: Prevent field failures. The Process: Structural Optimization & Analysis to predict failure points before cutting a single piece of material. What My Clients Say: "Sebastian’s attention to detail... reduced total manufacturing time by hours; this project has truly changed my life." - LOBA Corporation "The simulation insights were invaluable, and the detailed presentation made everything clear." - DBS Studio Ready to engineer a product that lasts?
