About

I design and build products where mechanics, software and interfaces have to agree.

I am Oluş Emre Demir, a product and UX engineer working across mechanical constraints, embedded logic, interface systems and early product strategy.

I like projects where the answer cannot live in only one layer. A useful product has to make sense as an object, as a system, as an interface and as a thing someone can actually build, ship, maintain and use.

My work usually starts with a rough idea, a technical constraint or a messy workflow. I turn that into a clearer product model, then move toward prototypes, interface flows, implementation details and the decisions that make the product easier to manufacture, explain and operate.

What I build

I build product systems, UX flows, internal tools, technical interfaces and prototypes for hardware-adjacent products. I am comfortable moving between a product map, a screen, a firmware behavior, a manufacturing constraint and the small details that make the final experience feel coherent.

I care about products that survive contact with reality: interfaces that match the operator workflow, components that respect DFM decisions, dashboards that expose the right state, and prototypes that answer the riskiest question instead of only looking finished.

How I work

I work from first principles. I clarify the user, the job, the physical or technical limit, and the failure mode before I polish the surface. Then I reduce moving parts, prototype the uncertain layer and make the product language simple enough that engineering, design and business decisions can point in the same direction.

I prefer small loops with real evidence: sketch the model, build the minimum working surface, test the interaction, remove what does not matter, and keep tightening the relationship between product logic and implementation.

Where I am useful

I am useful when a product sits between disciplines: a device needs a usable control surface, a technical workflow needs a clearer interface, an early venture needs to find the shortest path from concept to market signal, or a team needs to translate manufacturing constraints into product decisions.

My range is strongest around product thinking, UX systems, prototyping, DFM strategy, embedded behavior, interface design and hands-on delivery. I do not treat those as separate departments; I treat them as parts of the same product system.

What I care about

I care about clarity, buildability and taste. I want the product to be understandable without a long explanation, the engineering choices to be grounded in real constraints, and the interface to feel calm, direct and intentional.

I avoid unnecessary complexity. The best version of a product is usually the one where the hard decisions are visible in the simplicity of the final system.
