Dundua Consulting builds and supports federal environmental software systems. We've been in the EPA space since 2002. We know the systems, the agencies, and the constraints — and we know how to ship things that hold up.
We're a small firm. That's on purpose. It means you actually talk to the people doing the work.
David has been building large-scale software systems since 2000. He started working on federal environmental applications in 2002 — first at CSC, then through Innovate, and eventually through Dundua Consulting, which he founded in 2012.
He's the tech lead for EPA's RCRAInfo system — the national database used to track hazardous waste. He helped grow the system from a few hundred industry users to over 160,000 and led the migration to AWS. Before that, he spent nearly a decade on EPA's Central Data Exchange (CDX), building everything from the original node architecture to the CROMERR electronic signature system.
Earlier in his career, he co-founded Clustrix, a distributed database startup that went through Y Combinator in 2006. He holds a BS in Computer Science from the University of Maryland.
Gladys specializes in financial and environmental data. She brings analytical depth to the work — whether that's building models, working through messy datasets, or making sense of complex reporting requirements.
She programs primarily in Python and has worked on large-scale analysis of hazardous waste data. She also performed complex data extraction for Treatment, Storage, and Disposal Facility (TSDF) incident reporting — turning unstructured data into structured information that EPA and the public can actually use.
Earlier in her career, Gladys ran a real-estate development company, handling project management from the ground up. That background gives her a practical, business-first perspective that she carries into her technical work.
She holds a BA in Finance from Marymount University and an Advanced Data Science and Machine Learning certificate. She speaks English, Russian, and German fluently.
We're not a huge shop with a service for everything. These are the areas we actually know well.
Full-stack development across Java, Python, C#, and more. We've built everything from web services APIs to complex enterprise applications serving tens of thousands of users.
Data modeling, analysis, and practical AI tools. We work with environmental and financial datasets and build things that actually help people make decisions — not just dashboards nobody reads.
We know EPA's data ecosystem deeply. CDX, RCRAInfo, TRI, ICIS, e-Manifest — we've worked in these systems for years. We can help with data collection, reporting, and research integration.
We understand the Exchange Network, the CDX node architecture, CROMERR, and the web of systems that make federal environmental reporting work. If you're trying to plug in, we can help.
Interfaces that don't require a manual. We design for real users — regulators, industry filers, agency staff — and we know what they actually need from a screen.
We led the migration of a major federal system to AWS. We know how to do it carefully — with minimal disruption and a clear rollback plan. Cloud doesn't have to mean chaos.
Most of our work has been for EPA. We know that world well — the politics, the constraints, the systems that have been running since 2002.
The national system for tracking hazardous waste — generators, transporters, treatment and disposal facilities. David has been tech lead since version 6. He helped grow the system from a few hundred industry users to over 160,000 registered users.
EPA's Central Data Exchange — the central hub connecting states, industry, and federal agencies for environmental data reporting. David worked on CDX for over a decade, including building the original Node and leading the CROMERR electronic signature system.
The electronic manifesting system for hazardous waste transport — replacing paper manifests that had been in use since the 1980s. David participated in the design and development of the system as part of the RCRAInfo team.
The infrastructure connecting state environmental agencies to EPA's databases. David worked across multiple Exchange Network-connected systems throughout his career, building and maintaining the node-based web services architecture.
We write about what we know — federal systems, environmental data, and building software in complex environments.
