Real-time payments ledger
Rebuilt a batch ledger into an event-sourced system processing transactions as they land — with a full audit trail.
Dual Stack Labs is a software engineering studio. From first commit to production traffic, we design, build, and ship systems that hold up under load — front to back.
* Representative engagements. Client names withheld under NDA.
One team across the whole stack — so nothing falls through the gaps between front end, back end and infrastructure.
A small senior team, a short path between idea and production. No hand-offs to junior benches, no surprises in the invoice.
We dig into the problem, the constraints and the users before a line of code. Clear scope, honest estimates.
We design the system for where you are headed — data models, interfaces and infra that won’t box you in.
Tight feedback loops, real code in your hands every week, tests and reviews baked into the flow.
We deploy, observe and tune in production — then hand over something your team is glad to own.
We build the boring machinery that makes shipping safe — one-command deploys, green-only releases, and infra you can read. The exciting part is your product.
No account managers, no offshore relay. You work directly with the senior engineers writing your code — the people who actually answer the pager.
Tell us what you’re building. We’ll come back within a day with honest thoughts on scope, timeline and approach.
