The situation
Reachr is a business development platform built for independent recruiters, and the job was to add email sequencing inside a recruiting MVP without disrupting the host architecture. The existing MVP gave recruiters a place to manage their contacts, but it had no way to design, run, or automate multi-step email outreach, the outbound side of the business that turns a contact database into a working pipeline.
The brief was specific: keep it lightweight, fit it inside the existing architecture, and keep it maintainable. The feature carried real commercial weight. Outreach sequencing was the difference between a contact list and a working business development product, and Reachr's roadmap depended on it.
What we built
The engagement ran as a fixed-scope feature build for an existing product: a tech lead and one mid-level full-stack engineer, working agile sprints with sprint-by-sprint sign-off from Reachr's CTO. Scope was fixed, and nothing carried over into adjacent parts of the product unless the team flagged it first.
The feature lets recruiters build email sequences with multiple steps, edit them on the fly, and automate dispatch against the contact lists already living in the platform. Each sequence carries its own trigger logic, step ordering, send windows, and stop conditions, so a sequence halts automatically when a contact replies or moves to a different state.
On the stack: React and Next.js on the frontend, Node.js and PostgreSQL on the backend. Figma carried the design reference and GitHub carried version control and code review. Code quality and readability were held to the bar of the host MVP throughout, so the feature reads like part of the original codebase rather than a contractor drop-in.
CTO-approved code reviews ran every sprint, and testing covered both the happy path and edge cases: sequence step deletion mid-run, a contact replying during a multi-step send, and time-zone scheduling. Teams considering similar work can see how [AI product engineering](/services/ai-product-engineering) gets scoped as a fixed feature build rather than an open-ended project.
Outcome
The email sequencing feature shipped as a production-integrated part of the Reachr MVP, not a bolt-on. The code-review bar held to the in-house MVP standard every sprint. The collaboration is ongoing; the feature is in production use.
"Overall, their project management is good. I'm very happy with my lead engineer."

Engagement FAQ
How long does a fixed-scope feature build for an existing product take, and what team size is needed?
For Reachr, a two-person team — one tech lead and one mid-level full-stack engineer — shipped the full multi-step sequencing feature across agile sprints, with sprint-by-sprint sign-off from the client's CTO. A small, focused team works well when scope is fixed and the feature needs to integrate cleanly into code someone else already wrote.
How do you keep a new feature from breaking an existing product's code quality?
On the Reachr build, code quality and readability were held to the same bar as the host MVP, with CTO-approved code reviews every sprint. Testing covered edge cases specific to the feature, including sequence step deletion mid-run and time-zone scheduling conflicts.
Should we build email sequencing into our product or use an existing tool?
Build it if outreach is core to what you sell. For Reachr, sequencing was the difference between a contact database and a working business development product, and a two-person fixed-scope team shipped it inside the existing MVP without disrupting the architecture. If outreach is peripheral, an off-the-shelf tool is usually the faster answer.
Can email outreach automation handle replies and stop sequences automatically?
Yes. The sequencing feature built for Reachr includes stop conditions so a sequence halts automatically when a contact replies or moves to a different state, alongside trigger logic, step ordering, and configurable send windows.
What does "fixed scope" mean in a feature-level software development engagement?
For Reachr, fixed scope meant the two-person team stayed inside the email sequencing feature and did not expand into adjacent parts of the product unless the client flagged it explicitly. That kept the build predictable and the codebase change limited to what was actually needed.
