These case studies document production software I have designed, built, or led as a senior full-stack and AI agent engineer. Each write-up is based on the live product, the business problem it solves, and the engineering work required to ship and operate it in the real world—not mockups or concept work.
You will find AI and SaaS platforms (venue sales automation, free GPT-4 marketing tools), logistics and mobility products (on-demand courier and ride-hailing in Jamaica), corporate and local business sites (energy trading in Dubai, multi-location auto repair in Miami). Every indexed page links to the public site, summarizes the role, lists concrete deliverables, and explains the outcome for the client or end users.
If you are evaluating fit for a similar build—AI agents, custom CRM, React Native apps, Next.js SaaS, Stripe billing, or SEO-heavy marketing sites—use these pages as reference work. For a new engagement, start from the contact section on the home page or open any case study below for full technical and product detail.

Lead Engineer
AI sales agents for venues — qualify leads, automate follow-up, and book tours across web, SMS, and email.
Delivered multi-channel lead qualification, follow-up and tour-scheduling workflows with shared conversation history and human review controls.
Platform capabilities I helped engineer include a unified knowledgebase (pricing, packages, policies), configurable guardrails for escalation and tone, Draft Mode for human-reviewed replies that retrain the agent, a Playground for pre-launch testing, lead management across channels, custom workflows and campaigns, and analytics on lead journey and conversion. White-glove onboarding — the kind of integration work described on my [AI sales agent development](/services/custom-ai-sales-agent-developer) page — connects lead sources, shared inboxes, calendars, and existing event-management tools.
