An integration engineering firm - not a competitor to implementation partners.
We help software companies, digital agencies, platform partners, and technology consultancies deliver projects they otherwise could not, by engineering the connections between systems.
Nearly three decades engineering the space between systems.
eProxim was founded in 1997 and has since delivered hundreds of successful projects across payments, travel, telecom, billing, financial services, healthcare, and manufacturing. Many of the systems we built remain in core production years later - in at least one case, for more than a decade of continuous operation.
Today a dedicated team of engineers and architects delivers that work from three offices across three continents - giving partners follow-the-sun coverage and the depth to take on complex, long-lived integrations with confidence.
Who We Serve
Leadership
eProxim is founder-led and team-delivered - one architect’s standard, carried out by a full engineering organization.
Jayant Chaudhary
Jayant Chaudhary founded eProxim in 1997 and brings roughly three decades of enterprise technology leadership to the firm, spanning technical architecture, systems integration, and technology strategy for organizations from global enterprises to fast-moving startups.
He has held senior roles including VP Technology Integrator at American Express, CTO at Travel Syndication Technology, and Technical Architect at AT&T. Earlier, he architected a next-generation airline inventory-control system at SITA that was years ahead of the industry, and served as product architect and development manager at Flamenco Networks - experience spanning payments, travel, and telecom at scale.
That depth is why partners trust eProxim with their most difficult integration problems: behind the firm is a leader who has repeatedly defined the architecture, chosen the right technology, and delivered.
Solution architects who scope, blueprint, and de-risk every engagement before build.
API, middleware, and event-pipeline engineers across the .NET, PHP, and JavaScript stacks.
Dedicated test engineers who validate edge cases and failure conditions before go-live.
A support team monitoring live integrations so partners never find out something broke first.
eProxim’s delivery organization brings together seasoned professionals-including solution architects, integration engineers, software developers, QA specialists, DevOps engineers, and project managers-across the United States, Romania, and India. Every engagement is led by senior technical leadership and supported by specialized engineering teams, enabling us to scale from targeted integrations to enterprise-wide modernization initiatives without compromising quality or accountability.
