Tap2Dine
POS / Self-service kiosks
Restaurants & Fast Food

Results:

Elimination of order loss scenarios

Stable POS operation during network outages

Reliable payment processing under degraded conditions

Increased customer satisfaction

Context

Tap2Dine is a self-service ordering and POS system used in restaurants and fast-food chains.
Customers place orders via kiosks or tablets, complete payments, and expect fast, uninterrupted service.

The system integrates with kitchen systems, printers, payment gateways, and delivery platforms.

Primary mission-critical requirement:
Orders and payments must be processed reliably without delay, duplication, or loss.

Problem, challenge

Tap2Dine operated in a real-world environment with constant disruptions:

unstable internet connectivity
third-party API failures
kiosk crashes
payment disruptions

As a result:

orders could be lost
payments could fail or require retry
failures were hard to trace

The core issue: the system was not predictable under failure conditions.

As part of EDC technology, the client completed a Crash & Risk Assessment Form describing critical operations.

Key findings:

payment processing is mission-critical
order transmission must not fail
system must operate even during connectivity issues

How we helped solve the problem

We applied EDC Reliability technology, redesigning the system to remain operational even when parts fail. Key components:

Offline-first architecture: orders can be created without internet
Local order persistence: no data loss during crashes
Real-time synchronization: automatic recovery after reconnect
Payment resilience: local terminal communication
Device redundancy: continue orders on another kiosk

We conducted multiple iterations of risk analysis and architecture design:

Final reliability architecture:

The solution focuses on:

offline operation and delayed sync
removal of single points of failure
data duplication and recovery
predictable behavior under failure

Key reliability improvements

No order loss: orders stored locally and synced continuously
Offline operation: system works even during long outages
Resilient payments: reduced dependency on cloud availability
Full traceability: logging and audit trail

Result

The system was transformed from a cloud-dependent POS into a resilient, distributed system.

Key outcome:
The POS continues to operate reliably even during network failures, device crashes, and third-party outages - ensuring uninterrupted business operations.

Score Tickets | Reliable ticket delivery

Score Tickets
Chicago, USA
E-commerce

Results:

Increased system reliability

Customer satisfaction improvements

Context

Score Tickets is an e-commerce platform that sells tickets in large volumes, with a focus on timely delivery.
The company relies heavily on third-party services for its delivery operations.

Primary mission-critical parameter for the business is the ticket delivery deadline.

Problem, challenge

Score Tickets handles large-scale ticket sales with strict delivery deadlines, making reliability crucial.
Even minor delays can impact many customers, especially during high-demand events. The company's heavy reliance on third-party services like UPS for delivery increases the risk of disruptions, further emphasizing the need for a robust automation.

As the first component of EDC technology (Expertise), we requested the customer to complete a Crash & Risk Assessment Form , which provides a business overview with focus on mission-critical aspects.

The customer has provided the completed form :

Based on this document and an additional round of communication, the Implemica team began analyzing the critical components of the customer's business.

One of the main critical parameters for the business is the ticket delivery deadline.
Example: A critical delivery deadline for a concert ticket, with the venue a 2-hour drive away, would be 2 hours and 30 minutes before the concert begins.

How we helped solve the problem

To address these risks, we integrated EDC Reliability technology, which improves software reliability by duplicating critical functions such as

shipping,
delivery status checks, and
instant address validation across multiple providers.

As the second component of EDC technology (Duplication), Implemica prepared a roadmap for reliable automation: Crash and Risk Assessment Report :

It focuses on ensuring that critical elements of the customer's business operate reliably.

Example of a reliable approach: If UPS or other third-party services experience temporary or extended outages, alternative providers like FedEx or local couriers are automatically engaged to ensure service continuity.

After a discussion, and with slight adjustments, the plan was accepted, and the reliable automation was built and delivered to the customer.

Key reliable components of the solution included:

Alternative shipping providers: In case of delivery service unavailability, alternate shipping providers or local couriers are engaged.
Constant checks for expected delivery time: If expected delivery time falls behind critical delivery time, or other delay-related risks are expected, fallback to alternative delivery options, or inform the end customer.
Redundancy in instant actions backed by thirdparties (e.g. address validation): When UPS fails / unavailable, FedEx or other couriers are engaged.

Productivity

Results:

Simplifies Cloud Deployments

Enhances Developer Productivity

Versatility Across Platforms

Context

Cloud developers, in their everyday activities, often switch between multiple tools to deploy applications, which can disrupt the workflow and increase the risk of errors.

Problem, challenge

Each cloud platform requires unique configurations and tools, leading to a complex and time-consuming deployment process.

Each platform demands distinct configurations, security protocols, and deployment strategies, which can vary significantly even between services within the same platform (e.g., AWS EC2 vs. S3).

This fragmentation necessitates the use of multiple deployment tools and interfaces, leading to a complex, error-prone, and time-consuming deployment process. Additionally, managing updates and maintaining consistency across various environments can further complicate cloud deployments, adding layers of complexity that detract from coding and innovation.

Being software engineers ourselves, we deeply understand the issue and so we came with a solution.

How we helped solve the problem

DryPush integrates deployment operations into the most popular IntelliJ IDEs, providing a single interface to manage deployments across cloud services:

Amazon Web Services (EC2, S3, Elastic Beanstalk, CloudFront, etc),
Azure,
Google Cloud Platform,
DigitalOcean,
Standalone servers,

thereby streamlining the process and enhancing developer productivity.
