Outcomes shipped

A leading hospitality recruitment platform came to Armakuni for recruitment platform modernization at scale: microservices, serverless automation, intelligent matching, centralized analytics.

The challenge

A platform modernization engagement that addressed scaling, recruitment intelligence, and analytics in parallel, rebuilding Hcareers as a cloud-native foundation Virgil can build on for the next decade of hospitality hiring.

Scale: 600,000+ daily users at peak after scaling. Thousands of hospitality employers ranging from independent restaurants to multi-property hotel groups. Millions of applications processed annually across the platform.

What we built

Armakuni delivered recruitment platform modernization at scale: microservices, serverless automation, intelligent matching, centralized analytics. The engagement ran as multiple fixed-scope SOWs covering platform re-architecture, recruitment workflow redesign, analytics and observability, and ATS integration.

The outcomes

5 measurable outcomes shipped across the engagement. The ones that moved the business the most:

10x
scaling capacity, now handling 600,000+ daily users at peak
60%
faster search query response through Amazon OpenSearch and ElastiCache
45%
reduction in data indexing time
80%
reduction in manual recruiter tasks

10x scaling capacity, now handling 600,000+ daily users at peak. The platform absorbs peak load without performance degradation, removing the seasonal capacity planning that consumed engineering attention before every busy hospitality hiring window.

60% faster search query response through Amazon OpenSearch and ElastiCache. Candidates and recruiters get sub-second results across millions of records, so the platform feels as responsive as the consumer apps users compare it to.

45% reduction in data indexing time. Optimized pipelines and parallel processing surface new jobs and updated profiles faster, closing the freshness gap that used to lose candidates to faster competitors.

80% reduction in manual recruiter tasks. Automated resume parsing, intelligent matching, asynchronous bulk posting, and ATS-integrated workflows let recruiters work shortlisted candidates instead of inbox triage.

Bulk job posting that completes in minutes rather than hours. For multi-property operators this removes the workflow friction that pushed enterprise customers to faster platforms and unblocks deal sizes the commercial team could not otherwise close.
