Cordytech LLC is a software and web development company built around a simple conviction: the hard part is rarely the idea, and almost always the engineering underneath it. We learned that running email sending infrastructure for companies whose revenue depends on where their mail lands — provisioning the servers, publishing the DNS, tuning PowerMTA, warming the IPs, and answering for the numbers afterwards. That work does not reward cleverness so much as it punishes carelessness, and it shaped how we approach everything else.
Three engagements taught us the trade. We rebuilt Mobicentrum's sending operation between September 2023 and June 2025, and wrote Mailflow while we were doing it — the tool exists because we were the ones doing the manual work and refused to do it by hand a second time. We have run Relentia's infrastructure since January 2024, our deepest engagement, including three separate per-ISP reporting applications for Yahoo, Outlook and Gmail and a private tool that keeps their seed mailboxes alive. We have run EMG's remotely since January 2025, which forced every habit that a room lets you skip: the configuration lives in an application both sides can read, not in one engineer's memory.
Around that client work, Cordytech offers the same engineering as a service — custom web application development, multi-tenant SaaS product engineering, and platform and AI integration — for teams building their own product. And we ship our own apps as reference builds of how we work: Mailflow, Revline and Storebridge came out of the sending world, Ledgerline handles finance operations, and Fieldshift coordinates field-service teams. Two are live, three are in active development, and all of them are things we run rather than only sell.
We are a small, senior team that prefers depth to breadth. We build for the operator, ship in usable slices, and treat the unglamorous parts — authentication, security, observability, tests — as the actual product rather than the paperwork around it. We take positions: that internal tooling should wait until you have done the job by hand long enough to know which parts are merely boring and which are dangerous; that a report should be shaped like the thing it reports on; that training the client's team is part of the deliverable, not an upsell.
We do not do self-serve sign-ups or checkout flows. Everything we build is demo-led and scoped, because the work that matters starts with understanding your process, not pointing you at a pricing page. If that sounds like the kind of team you want on the problem, the people who would actually do the work are listed below — tell us what you are trying to build and we will tell you honestly whether we are the right fit.
