Crafting data‑driven interfaces for founders and startups.

At Polygraph, we worked with Hesham on a variety of projects over several years. We greatly appreciated forming an ongoing relationship with him as a contractor.

He was consistently a reliable resource on both the development and data sides of our work. Hesham always adapted to client needs as projects progressed, maintaining steady communication and awareness of deadlines.

I worked with Hesham for over two years on full-time product development and data visualization.

He played a key role in designing and coding fully functional React prototypes using real data, and building a complex design system — including reusable data visualization components.

I originally brought him in to help design a tool for microbiome research, which evolved into a full redesign of our metabolomics product — transforming a static PDF deliverable into a B2B SaaS platform.

Hesham’s greatest strength is making sense of complexity — both conceptually and technically. He quickly understood the nuances of metabolomics and focused on what mattered most.

Hesham did a lot of heavy lifting with minimal technical support, and always gave back to the team with detailed design, code, documentation, and personal availability.

He had no issues working across the org — from senior devs to scientists, VPs, and our CEO. As a director, I only had to set my weekly goals and ask what he needed — and he was off and running.

He takes his work seriously, stays open to feedback, and approaches every task — big or small — with thought and care.
