About PBX Digital
Founder-led .NET and React engineering, built to run under your name.
PBX Digital is a founder-led engineering bench for software agencies and IT consultancies. We join your delivery as a second stream of senior .NET and React work — in your tools, on your cadence, shipped under your name. The code stays reliable, secure, and maintainable long after handover.
- One line from first call to handover
- No junior or account manager in between
- Reviewed before it reaches your client

Delivery lens
- A second delivery stream — invisible to your client, or named as a partner.
- Architecture reviewed for security, scale, and maintainability.
- You deal directly with the person writing the code.
Leadership Profile
Manpreet Singh
Founder & Lead Architect
Agencies bring me in when they have more .NET and React work than people — and the work still has to be right.
I work full-time as a developer on a production warehouse management system — high-volume transactional data, .NET services, and EDI and API integrations, in an environment where a failed sync means the warehouse stops. That is the standard I hold PBX work to.
Through PBX Digital, agencies and consultancies bring that experience onto their own client work — as senior .NET and React capacity that slots into an existing team without a hiring round. I have seen where builds go wrong: siloed data, manual bottlenecks, and integrations that fail silently.
My focus is resilient .NET middleware and secure API integration between systems that were never designed to talk to each other — built on Clean Architecture and SOLID, with CodeQL and Qodana in the pipeline from the first commit. Work with PBX and you deal directly with the person writing the code — no hand-off to a junior or an account manager.
Who you work with
- .NET middleware & APIs
- EDI & third-party integration
- SQL Server data modelling
- Clean Architecture & SOLID
Engineering baseline
Clean Architecture, SOLID design, and repository-level security checks.
Integration focus
Connecting the platforms your client's stack depends on — without forcing a rebuild.
PBX Engineering Standards
Standards that protect your timeline and your client.
The bench is deliberately small and senior — you get direct access to the people writing the code, not a layer of project managers. These standards exist to reduce delivery risk on your client work and keep the architecture sound as it grows.
01
Nothing gets handed off
No junior developer or account manager between your team and the work. The founder guides every architectural decision, so the design holds together from first call to handover — and your client only ever sees finished work.
02
Security checks from the start
Security and performance are built into the repository from the first commit. Static analysis, code scanning, and release discipline catch vulnerabilities and regressions before they reach production.
03
We work in your tools
PBX works in your Slack or Teams, Jira or Azure DevOps, and deployment workflows, on your team's cadence — white-labelled and invisible to your client, or named as a partner.
Why it matters
The result is a direct line from your client's requirements to secure, maintainable delivery — and a partner your team can bring into a build without adding delivery risk. It matters most on integration-heavy work, where a mistake is expensive to unwind.
