Case Studies/Truck-4
A commercial vehicle rental marketplace — find, lease, or purchase trucks, tractors, and trailers with secure auth, uploads, and microservices scale.

Client requirement
Truck-4 needed a microservices marketplace for commercial rentals — OTP auth, truck management, secure file uploads, third-party maps/email, compliance tooling, and Kubernetes-ready scale.
What we inherited, and exactly how each constraint was resolved.
Dependent microservices needed reliable communication without tanking response times.
We used REST APIs plus async messaging with RabbitMQ between services.
Uploaded files risked malware that could crash servers or corrupt data.
We scan uploads in real time with ClamAV before they are accepted.
The platform had to scale services and data as demand grew.
We ran services on Kubernetes for independent deploy and demand-based scaling.
Auth had to stay fast and trustworthy when upstream pieces failed.
We added fallbacks and monitoring so verification stays available during disruptions.
Integration testing across many services needed early failure detection.
We used SonarQube and Azure DevOps CI pipelines to catch issues across the lifecycle.
Deploying many services onto Kubernetes clusters was operationally heavy.
We automated deploys with Azure DevOps and Helm charts for repeatable releases.
Latency and uneven performance missed response-rate targets.
We added caching, query optimization, and profiling to remove bottlenecks.
Keeping data consistent across services was complex under load.
We used eventual consistency patterns and distributed transactions where needed.
Independently deployable services for auth, trucks, uploads, and related domains.
OTP verification and access control via Twilio for trusted sign-in.
Malware scanning on uploads before they hit storage or processing.
Google Maps for location/routes and SendGrid for transactional email.
Tracking for driver qualifications and vehicle inspections with automated alerts.
Code, security, and process work improved overall platform performance.
Lower latency and higher reliability improved day-to-day user experience.
Auth, service isolation, and ClamAV scanning strengthened the security posture.
Automated deploy and Kubernetes scaling cut ops cost and raised throughput.
Better UX and trust supported stronger retention in the rental marketplace.
