I deliver production-ready imagery for global beauty brands, editorial publications, and commercial campaigns. My professional background includes collaborations with Adobe and a focus on high-fidelity visual standards for the fashion and beauty industries. Non-destructive 16-bit workflow This is the core of my process. I maintain a clean and professional layer structure to ensure every file remains fully adjustable and retains its integrity at any scale. My method is built for high-end production where quality must hold from digital displays to large-format print. Controlled AI and Hybrid Post-Production I use generative tools and advanced algorithms as a supportive component of the workflow. I do not rely on automated filters. My role is to manually resolve the defects AI creates. I restore anatomy and textures to ensure the final result is authentic and meets professional standards. Core Services ● Beauty and portrait retouching for brands and magazines ● High-fidelity color grading and campaign consistency ● Commercial product retouching and rendering ● Complex compositing and generative refinement Professional Standards I prioritize quality over volume. Every frame undergoes a rigorous manual process including Dodge and Burn and surgical texture work. For new large-scale projects, I am open to a test frame to ensure my technical approach meets your specific production requirements.

Brine–CO₂ corrosion modelling, oil-field pipework (2025–26, active) — multiphase CFD with species transport. USC approved Valve (2025) — backflow-preventer pressure-loss validation to AWWA C510 across six configurations. EvansWerks (2023–26) — 32-month principal-engineer engagement for Product development Patented airless tyre (2026) — coupled FEA + thermal feasibility on an adaptive airless tyre (CalculiX + Gmsh). toronto university wind tunnel (2025) — contraction-section CFD achieving <1% velocity-profile RMS in the working section. Credentials: Mechanical Engineering, advanced simulation focus (in progress) · BSc.Eng (Hons) Mechanical Engineering, UKZN · Aerospace Systems Research Group affiliate since 2019 · 2× granted USPTO patents in cooling-system technology.
