Introduction

Expo Mexico runs on bookings. As a company that manages event-space and venue rentals, its entire commercial operation flows through one module on Salesforce: the system that captures, processes, and manages every reservation. Built out by external consultants over roughly two years, it had become the operational heart of the business, the tool the team touches every single day.

The problem was that the heart kept stopping. The system meant to run all of it couldn't get through an ordinary day without breaking.

The Challenge

The failures weren't happening under stress. Even at ordinary data volumes — no spikes, no edge cases — the booking module would collapse, and processing reservations became unreliable. For a business where booking is the operation, that's not a technical annoyance; it's a direct risk to revenue and to the team's confidence in its own tools.

When Hikko got access to the sandbox and ran a technical analysis, the diagnosis was clear and, in its own way, reassuring: this was never a limitation of the Salesforce platform. Apex could handle the workload comfortably. The instability lived in how the solution had been implemented — database operations running inside loops, redundant queries firing on every event, logic written to process one record at a time instead of in batches, and the same code duplicated across classes. Individually small, together they were quietly burning through platform limits, raising the risk of failure as volumes grew, and — just as damaging — making the module almost impossible to evolve safely.

The Solution

Hikko didn't recommend starting over. The business logic was sound and the foundation was salvageable, so migrating to another platform or rewriting the module from scratch would have meant spending months to rebuild something Expo Mexico essentially already had. Instead, we stabilized and optimized the existing module directly on Apex — realigning the code to Salesforce's recommended standards without changing the workflow the team relied on. From the outside, Expo Mexico's people would book and manage events exactly as before. Underneath, the engine would finally behave.

What We Delivered

• A stabilized booking engine: we refactored the critical classes driving the failures, eliminated the database operations trapped inside loops, and redesigned methods to process reservations in batches instead of one record at a time — cutting platform-limit consumption dramatically.
• A cleaner, faster foundation: redundant queries were removed and duplicated logic consolidated, bringing the codebase in line with Apex best practices and reducing the number of queries fired on every event.
• Confidence that nothing broke: we reviewed related dependencies and automations, ran technical testing, and validated behavior directly with the business team, confirming the workflow was preserved end to end.
• A base ready to grow: we delivered updated technical documentation and clear recommendations for future evolution, so new features can be added on top of a stable module rather than at its expense.

Conclusion

Expo Mexico didn't need a new platform. They needed someone who could quickly tell the difference between a platform limit and an implementation problem, fix the right thing, and give them back a system they could trust.

In about three weeks — analysis and development included — a module the team had come to consider inoperable was running reliably on a clean, best-practice foundation, with zero disruption to how they work. And to keep it healthy as the business grows, Hikko continues to provide technical governance and evolutionary support: a monthly technical committee, preventive code review, and ongoing monitoring of platform-limit consumption.
