Granton Advertising

We workked with a team of 10 people from Granton Advertising for roughly 16 weeks. They were in our Office helping us to develop data pipelines reorganize our data capture system. They were very bright, they knew what they were doing , well trained. And they were really friendly, totally open, they took time to make sure we understood thier processes and roadmaps. I found them to be totaly open and willing to share. I liked working with them very much. I made some good friends.

We engaged Granton Advertising to modernize our legacy technical architecture and eliminate data fragmentation across our multi-national footprint. Granton's engineering team decoupled our legacy core by deploying an event-driven microservices architecture. They built a React.js frontend on Vercel with a Node.js and GraphQL middleware plane. To handle massive concurrent mutations without packet loss, they implemented Apache Kafka buffers and an Optimistic Concurrency Control (OCC) strategy utilizing atomic PostgreSQL JSONB deep document merging. They also integrated OpenAI's GPT API and LangChain into a WhatsApp customer-intake framework to automate data sanitization.
They pulled off a complex, multi-location deployment across international boundaries on an aggressive timeline. The architecture is incredibly sophisticated; implementing GraphQL eliminated data over-fetching at our retail terminals, cutting network payload weights by 70%. Their use of Kafka and PostgreSQL JSONB completely eliminated row-locking contention during peak hours, while the LangChain/GPT workflows dropped data pipeline ingestion error rates to near zero. They bridged physical sales with cloud architecture, giving us live telemetry to calculate precise Average Revenue Per User (ARPU).

As the Operations Manager for Kuflilicious, I partnered with Granton Advertising for a major multi-location digital infrastructure rollout across eight of our branches (six in the UAE and two in India).
Granton’s engineering team showed technical autonomy, building a highly responsive full-stack architecture utilizing React.js, Node.js, and a robust PostgreSQL database on an pretty aggressive three-month timeline. They went a step further by implementing a strongly typed GraphQL API layer that eliminated data over-fetching at our physical retail terminals and event booths. Additionally, they integrated OpenAI's GPT API and LangChain workflows into an automated WhatsApp customer-intake framework, which streamlined our guest data ingestion end to end.
The project did experience an initial scheduling setback. Balancing the integration between our legacy POS system and their new custom enterprise platform caused early friction and some hesitation from our internal IT department. However, Granton’s project manager handled this challenge excellently. The PM listened closely to everyone's concerns, focused on direct problem-solving, helped forge a cross-team consensus, and cleared the impediments to get our timeline back on track.
Despite that early hurdle, the team handled themselves very well under tight eight-week sprint timelines. The new system has dramatically reduced our administrative overhead and improved data accuracy across all international regions. I highly recommend Granton Advertising for complex full-stack software development and practical enterprise AI implementations.

I met with the Granton representative at the World Trade Center last weekend. I had some questions regarding my purchase and the girls took time to review the Terms & Conditions of the promotion clearly. They also answered all of my questions , and, they did it all with an extremely pleasent attitude. I actually enjoyed speaking with them. They deserve credit.

Granton Advertising helped us device customer acquisition very Strategic and methodical. It helped us improve our ARPU while keeping the CCA very minimal. Their methods helped us increase the Revenues while keeping the initial costs of giveaway very minimal. The communication was very clear and crisp while maintaining our goals intact. The support extended was exceptional throughout the project.
