I’m Kevin Yap. My professional foundation is in advanced manufacturing, Americas market development and technical-commercial leadership. My story also spans Singaporean roots, Air Force service, systems building, competition and creativity. BULL.S is the callsign that connects those worlds.
My journey began in Singapore: the Gifted Education Programme, Raffles Institution, and later service with the Republic of Singapore Air Force. Those chapters exposed me to very different kinds of work—from academic problem-solving and competition to the preparation and accountability required in air operations.
After developing my engineering foundation at Nanyang Technological University and working on maritime analysis with DNV GL, I moved into industrial additive manufacturing. My roles at 3D Metalforge, Endeavor 3D and BLT connected technical applications with customers, commercial decisions and markets across the Americas.
What connects the chapters is an interest in understanding how things work and helping others put that understanding to use. The timeline below links to the organizations and to the more detailed first-person career accounts.
I earned the callsign BULL.S during my service with the Republic of Singapore Air Force. It stayed with me after that chapter of my life and became the name I use for my personal identity and projects.
Today, the blue longhorn and red star bring together influences from Singapore and Texas—two places that have shaped my experience. The emblem is personal, but the principles behind it are familiar: preparation, determination, accountability and the willingness to take on difficult work.
It isn’t a separate business title or a manufactured brand story. It’s a name with a history, carried into the work I do now.
A closer look at the experiences behind the professional timeline—not separate awards or invented milestones.
The Gifted Education Programme and Raffles Institution are the opening chapters of my education in Singapore. The mix of academic challenges, sport and co-curricular activities made learning about more than a single subject or examination.
Education chaptersIn the RSAF, I served as an Air Operations Specialist with 145 Squadron after Command, Control and Communications training. The work involved operational and crew safety; my service also included joint exercises and an overseas detachment in India.
Air Force chapterEngineering at NTU and ferry-concept analysis at DNV GL built a bridge into manufacturing. The work that followed demanded not only technical understanding but also judgment about markets, customers, materials and delivery.
Engineering chaptersThe education, service and companies behind my story. The original educational and professional links return here alongside restored organization emblems, presented with updated career context.
Selected for Singapore’s Gifted Education Programme—an early opportunity to build critical-thinking habits and work through challenging academic problems.
The programme forms part of my educational foundation. I keep the official MOE link here for context, rather than treating the ministry emblem as a personal award.
Raffles Institution was part of my education in Singapore, with academic study alongside sport, co-curricular involvement and the friendships and expectations of school life.
The wider experience mattered: balancing schoolwork with competitive and group commitments introduced a different kind of preparation from classroom study alone.
Served as an Air Operations Specialist with 145 Squadron, supporting operational and crew safety. The experience taught me to prepare carefully, be accountable to others and perform under pressure. It was here that I earned the callsign BULL.S.
After Command, Control and Communications training, my service included joint exercises and an overseas detachment at Kalaikunda Air Force Station in India. I was recognized as Outstanding Serviceman of the Month in March 2013.
Developed my engineering foundation at NTU, learning to connect technical analysis and manufacturing considerations to practical problems. This period shaped the way I would later approach industrial applications.
The transition from service to university brought me back to the technical questions: how a design works, what constrains it, and how engineering choices affect outcomes.
Worked on the analysis of environmentally focused ferry concepts, including route assessments, engineering calculations and life-cycle considerations—a first exposure to engineering decisions in a commercial context.
The work was analytical rather than a finished ferry project I can claim as my own. Its value in the journey was learning to test proposals against practical requirements and environmental considerations.
Developed industrial additive manufacturing applications and global customer relationships, with work spanning technical feasibility, commercialization and international market-building from Singapore to Houston.
My scope included reviewing industrial drawings and applications, working with more than ten global accounts, and supporting the company's US expansion and Houston office setup. Publicly documented corporate initiatives, such as the PSA port project, are covered separately from my individual role.
As Senior Sales Engineer, managed ten national accounts and helped customers and engineers evaluate polymer and metal additive manufacturing applications before commercial decisions were made.
This was an opportunity to work close to the decision point between customer requirements and a viable manufacturing proposal—considering geometry, materials, process choices and production constraints.
Led Americas regional sales and market-development work in industrial metal additive manufacturing, creating customer and channel relationships and helping translate global capability into regional demand.
As Regional Manager (Americas), I worked across customers, distributors, industry events and cross-border coordination. My owner-reported commercial results and the distinction between personal contributions and company partnerships are documented in the BLT case study.
Two photographs retained from the earlier website. They document industry-facing moments rather than replace the detailed record of responsibilities and results.
The restored emblems identify places where I studied, served or worked. Their inclusion does not imply endorsement, affiliation today or permission to disclose nonpublic work. The external links lead to organizations or public programme information, rather than verification of my individual credentials.
Following my Americas regional leadership work in additive manufacturing, I’ve been exploring industrial intelligence tools, independent software and community projects. I’m interested in the point where practical experience reveals a problem worth solving.
Atlas, for example, grew from the commercial challenge of organizing scattered market, account and equipment information. It remains a private work in progress rather than a public commercial product. Other interests—including darts and photography—develop a different side of the same curiosity.
The industrial career is the foundation, not the entirety of the story. Selected work shows how these interests are becoming projects; Performance follows the competitive and creative side.
My career, projects and personal interests all shape the way I approach difficult work.
From industrial additive manufacturing applications to building markets across the Americas, my professional background is grounded in connecting technical capability with real customer needs.
Explore professional experience ↗Software experiments, photography, competitive sport and community projects keep me learning, challenge assumptions and help me approach unfamiliar problems with discipline.
View personal and technical projects ↗Lessons that travel between business, technology, sport and everyday life.
I prefer repeatable, scalable approaches to temporary fixes.
Good ideas need a route from discussion to practical outcomes.

Capabilities, relationships and good work compound over time.
Steel-tip and soft-tip darts, competitive pool, kiteboarding, skiing, snowboarding, shooting and parkour have all been part of the journey. Each discipline offers a different way to practice preparation, composure and adaptability.
Photography, street magic, branding and independent technology projects give me another outlet: the chance to understand an audience, shape an idea and make something real.
