Case Studies

How ABS Stopped Losing Families Online and Filled Their Pipeline With an AI Assistant

Ellie didn't just make the intake process nicer. She made it measurably more effective. Families get a faster, warmer experience. The ABS team spends zero time on data entry. And leads that used to slip through the cracks are now being captured automatically, around the clock.

Noorly: Engineering a Distraction-Free, Glassmorphism-Inspired Spiritual Companion

The client faced a market saturated with cluttered, poorly designed spiritual apps that hindered rather than helped focus. We built Noorly, a premium glassmorphism-based Tasbeeh companion, giving users a distraction-free, haptic-enabled environment to maintain their spiritual journey with total clarity.

FERRATI SPORTS: Building a High-Performance B2B E-commerce & Automation Platform

FERRATI SPORTS, an international manufacturer, needed a powerful SEO and highly reliable B2B digital system. We built a custom site using Next.js for full rendering control, implemented smart filtering for superior UX, and integrated AI automation to streamline the order inquiry and internal workflow, resulting in an efficient, future-proof platform for their global operations.

Minimap: E-commerce

The client faced the limitations of scaling a business solely through Instagram DMs and manual tracking. We built a custom Next.js and Firebase e-commerce platform, giving them a centralized system that simplified inventory management and provided a seamless, searchable shopping experience.

Direct Transport Solutions (DTS) — Engineering a Full-Scale, 90% Automated Logistics Platform

DTS faced a critical need to overcome a 90% manual workload and lack of real-time visibility9. We built a complete, full-stack TMS using Next.js and React Native that implemented real-time tracking10, a client booking portal, and an automated single-approval payroll system. This gave the client a future-proof, enterprise-grade solution that now saves the business significant daily administrative hours.

Word of Mouth — Building a Scalable Social Food Discovery Platform

The client faced the significant challenge of building a high-performance, cross-platform social application with a complex, personalized feed algorithm. We built a React Native and Supabase-backed solution with a custom-tuned algorithm and an enterprise-grade Admin Dashboard, giving them a future-proof platform with optimized performance and complete operational oversight.

Building an Enterprise-Grade B2B Lead Automation Engine

The client needed to scale highly personalized B2B outreach without increasing staff. We built an n8n-orchestrated B2B engine that uses AI to scrape prospect websites, write technical, hyper-personalized icebreakers, and manage the entire email campaign lifecycle automatically, resulting in up to 1,200 personalized emails sent every month and a hands-free pipeline for the sales team.

Elite Property: Achieving Cost Savings and 24/7 Support with an Intelligent AI Assistant

The client faced a major bottleneck in customer support and a failure to convert browsing users into active contacts, specifically not wanting to hire more people. We built a full real estate platform featuring an AI chatbot powered by a vector database and the Gemini model, giving them significant cost savings on staffing and a highly efficient, 24/7 engagement system that drives users directly to bookings and purchases.
