eProxim

eProxim is an integration engineering firm. Since 1997 we have built the technical layer that business systems depend on, from APIs and middleware to event-driven pipelines, data synchronization and managed integration. Most of that work is delivered for other firms: ERP and CRM implementation partners, commerce agencies, software vendors, managed service providers and fractional CIOs who own the client relationship and want a specialist underneath it.

We are a specialist rather than a general implementation partner, and that shapes how we work. We do not hold platform practices, we do not bid against our partners, and we do not contact their clients unless asked. We work under the partner's contracts and, where they prefer, under their brand, inside their tools, cadence and templates.

Our engineering comes from regulated, high-volume production systems in payments, travel and telecom, so idempotency, audit trails, observability and rollback plans are the default rather than an upsell. Published work includes a real-time settlement hub sustaining 240,000 transactions per second, a telecom mediation pipeline handling 1.4 million usage events per second, and a reporting platform that generates more than 25 million reports a month.

The firm is led by its founder, Jayant Chaudhary, whose career includes senior technology roles at American Express, AT&T and SITA, and its engineers work from Alpharetta, Iasi and Gurgaon. On difficult or at-risk projects we respond the same business day and begin with a one-day deep dive rather than a multi-week discovery.
