About Halo

Halo delivers deep technical expertise across financial services, healthcare, retail, and entertainment, helping organizations bring complex, high-stakes systems to life. With nearly two decades of experience, they operate as an end-to-end partner capable of architecting, developing, hardening, and integrating production-grade solutions where reliability, security, and performance cannot be compromised.

Their team has supported platforms reliant on Plaid, Stripe, payment processors, anti-fraud systems, identity verification solutions, and payment orchestration layers. Halo’s work spans headless e-commerce builds, payment stack implementations, embedded finance integrations, operational tooling, and data workflows across the entire customer lifecycle. What sets Halo apart is their ability to go beyond design and provide hands-on engineering, helping enterprises successfully ship systems that other agencies struggle to deliver.

Halo’s practical experience covers highly specialized domains including secure payment flows, PCI-sensitive architectures, tokenization, fraud detection, identity verification, compliance-aware interfaces, and distributed systems that demand high availability. They also bring expertise in multi-system data modeling, operational workflow design, and integrations across complex ecosystems.

In addition to client delivery, Halo runs a dedicated R&D Lab and an Applied AI & Agentic Systems Engineering group. This team develops custom AI platforms for Fortune-level organizations, including agentic applications, intelligent data layers, and automation systems designed to safely handle sensitive data such as PII, PCI, and PHI. With more than 1,500 projects delivered and a global team of over 300 builders, Halo has earned a reputation as the partner trusted to take on high-risk, high-complexity initiatives and consistently ship.
