The Problem :
Enterprise HR teams, especially those managing multiple subsidiaries or client companies, are forced to juggle disconnected tools for payroll, recruiting, performance, contracts, and IT assets. Onboarding a single employee can take days of manual paperwork, contract generation, and system provisioning across separate platforms that were never built to talk to each other. Payroll errors go unnoticed until they become costly, applicant tracking rarely connects to actual hiring outcomes, and leadership has no real visibility into attrition risk or workforce trends until it is too late. Holding companies, agencies, and multi-entity organizations needed a single, secure platform that could manage HR across every company they run, without losing data isolation between entities.
The Solution :
DualUp HCM is a mandant-capable HR operating system that unifies payroll, recruiting, performance management, contracts, expenses, and IT asset tracking into one platform, while keeping every managed company completely isolated and secure. Core workflows are automated end to end: new hires get a digital contract generated and sent for legally binding e-signature, IT hardware gets ordered, and system access gets provisioned automatically, cutting onboarding from days to minutes. The platform integrates natively with DATEV for payroll export, DocuSign for e-signatures, and Supabase for secure authentication and storage. An AI copilot layered across the system parses resumes, ranks candidates, flags payroll anomalies, and forecasts attrition risk before it becomes a retention problem.
The Challenge :
The core engineering challenge was building a true multi-tenant architecture where multiple independent companies, subsidiaries, or clients could share one platform while keeping their data, workflows, and permissions fully isolated from each other, all without sacrificing performance at scale. On top of that, the system had to connect deeply into real business infrastructure rather than existing as a standalone tool, meaning reliable DATEV payroll exports, legally binding DocuSign signature flows, and GDPR-compliant data handling across 40+ countries. Layering AI on top added another dimension: training resume parsing, sentiment-based churn prediction, and payroll anomaly detection to work reliably against messy, real-world HR data while staying explainable and trustworthy for HR decision-makers.
Summary :
DualUp HCM turns fragmented HR operations into a single, intelligent platform built for multi-entity organizations, cutting onboarding time from days to minutes and giving HR leaders real visibility into payroll accuracy, hiring pipelines, and attrition risk. Its built-in ROI calculator quantifies the impact directly, showing measurable monthly and annual savings from automated HR processes. The project demonstrates my ability to architect complex, secure, multi-tenant SaaS systems, integrate deeply with third-party infrastructure like DATEV and DocuSign, and layer practical AI features on top of real business workflows, combining enterprise-grade engineering with a genuinely usable, modern interface.
