About DRJS
Science, software and the judgement to connect them
DRJS Software & Consulting Ltd is founded and directed by Dr David Slade, an engineer and software builder whose work crosses applied mathematics, industrial modelling, data, architecture and digital product delivery.

Dr David SladeFounder & DirectorHow I build
Start with the system, then earn the simplicity
I enjoy problems that live between disciplines: where software must reflect a physical process, a model has to support a real decision, or a product needs both technical credibility and an interface people can trust.
My approach is to understand the mechanism, constraints and users before committing to a solution. I favour visible assumptions, small testable increments and architectures that a future team can operate. The result may be a model, an API, a SaaS product, a technical review or a course, but it should always leave the problem clearer than I found it.
Education
PhD, Mechanical Engineering
University of Leeds, 2009–2013
Research in numerical simulation of thin liquid films and coating flows, including adaptive time and mesh methods, multigrid techniques and a parallel Navier–Stokes finite-element solver implemented in C++.
Background spanning applied mathematics, mechanical engineering and chemical engineering applications.
Experience
Research depth, industrial context and software delivery
A career spent translating models and systems into tools that support design, operation and better technical decisions.
