I’m Sergio Perez Fontana, an Aerospace Engineer, Manager, and Technologist with over 30 years of experience in Flight Sciences and Structures. My career spans many successful aircraft programs at Boeing, Gulfstream, Bombardier, Bell Helicopter, and Embraer, where I led cross-functional teams in driving innovations through process and design optimization. I’ve led the implementation of advanced methodologies integrating advanced aerospace and exponential technologies for aircraft and other high-performance products maximizing efficiency and effectiveness. I have also developed a deeper specialty in Generative Design and Structural Optimization. Since 2014, I’ve explored and applied topology optimization and AI-driven generative design techniques, leveraging various generative design tools to inspire better, more efficient designs. For example, I contributed to achieving significant weight reduction in thick aluminum plates used to support heavy monuments on the Boeing VC-25B New Air Force One Presidential Aircraft, achieving tangible benefits in structural performance and cost. Traditional design methods often yield heavy, costly parts with underutilized material after long design processes. Every structural component, regardless of the scale of the project or budget, can benefit from my proprietary AI-driven workflows to transform conventional designs into structures that are: - Stronger and lighter: Eliminating unnecessary mass while exceeding performance requirements. - Optimized for manufacturability: Custom-tailored for efficient, scalable production using subtractive or additive processes. - Cost-effective and ready for validation: Minimizing engineering effort and material usage while seamlessly integrating into certification and operational workflows. This approach delivers high-quality structural engineering solutions faster and at a lower cost. Whether you’re developing an advanced component for a Martian flying vehicle or a flying hydrofoil board over water, I bring deep aerospace expertise and advanced AI tools to help you overcome your design challenges.

A beginning graphic designer with an associate’s degree looking to join the graphic design industry. My goal is to use my creative talents to benefit the company and bring joy to others. I'm knowledgeable in using various production software such as Photoshop, Maya, Libre Office, Unity, Animate, Illustrator, Indesign, and Wavepad. I’ve had practice in 2D/3D art production software. Working in Photoshop and Maya are two of my strongest skills. I enjoy creating art pieces or other 2D designs such as a website page, advertisement, or greeting card. There are also many miscellaneous objects and props I build in Maya for fun. One of my biggest projects was to design and build a 3D environment from scratch. Throughout all these, soft skills were also put to the test. Some examples intrude problem solving, improvising, and deciding on a different approach when my original plan doesn’t work. My specialty is building objects from a game or cartoon. I enjoy building things that are related to fun and games.

I excel at in CAD Design with a particular skill at modeling aerospace structural components and assemblies from old 2D drawings to facilitate manufacturing. The first part I modeled for machining included 7 sheets of detailed dimensions and complex geometry, and I nailed it in few weeks where others had spent several months and gave up. I worked professionally in CATIA v5 for 8 years including for Boeing having won the 2012 COE Top Gun XXV award. For the last 10 years I've been working in SolidWorks and AutoCAD for Honeywell and added Siemens NX 2 years ago. I am personally licensed with SolidWorks, and am willing to invest in CATIA, AutoCAD, or NX licenses as well if the work justifies it, otherwise there are VPN or remote desktop solutions if you have licenses available.

My design and manufacturing experience began with the challenge of the Formula Society of Automotive Engineers (FSAE) competition in 2004. Ten engineers worked for one year to design and manufacture an open wheel race car from scratch to compete against the world's top engineering schools. The year-long project solidified my years studying aspects of engineering design, analysis, testing, and manufacturing. Since then I have taken on multiple freelance projects, helping folks take innovative ideas and create engineering models and manufacturing drawings. My greatest strength is working with clients to optimize their design to work with modern manufacturing methods. Whether it's maximizing product strength through Finite Element Analysis (FEA) or minimizing manufacturing costs, we will work together to take your idea into reality with a thoughtful and clearly communicated plan followed by professional execution.
