About
Designing products that convert and scale.
I'm Digil David, a Senior UI/UX Designer and Product Design Lead at Würth UAE, where I've led digital product design for the GCC market since 2020. I started in graphic and web design and now turn business goals into human-centred products, from research to design systems to developer handoff.
I pair that with hands-on AI workflows (image prompting, Kling, VEO3, Runway, Higgsfield) and I build and ship my own products, from WhatsApp commerce to voice agents and SaaS tools. I'm happiest when a Figma file turns into something shipping.

Developer journey
Full-stack, with AI built in
I design the product and I write the code behind it. My path runs from computer engineering to full-stack apps, then LLM products, agentic AI and small language models.
Engineering roots
B.E. in Computer Engineering from Anna University, Chennai. Design and code have been part of the same toolbox from the start.
LLMs
Language model appsPrompt design, structured outputs, retrieval over your own data, and weighing quality against cost and latency.
Agentic AI
Agents and orchestrationTool calling, multi-step workflows, memory, guardrails and human-in-the-loop handoff.
SLMs
Small language modelsLightweight and on-device options, and when fine-tuning beats prompting for a narrow task.
Full-stack
Front end to databaseReact, Next.js, Node.js, Python and SQL, with APIs and data models designed around the UX.
Messaging & voice
WhatsApp and voice agentsWhatsApp Cloud API commerce flows and AI voice calling agents in regional languages.
Delivery
Ship and run itDocker and Azure, plus quick Vercel deploys for demos such as People Core HR.
