Automate the back office.

How does working with one engineer stay safe?

• Fixed price, in writing first

  After the 15-minute call you get a written quote with fixed scope, timeline and deliverables, within 48 hours and before any code is written.

• You own what is built

  Full ownership transfers at handover, with documentation and handoff-ready code your team can keep extending.

• One senior engineer, no layers

  The person you talk to does the building. One communication channel, daily async updates and a weekly demo during the build.

• A 14-day fix window

  Production deploy, documentation, and a 14-day fix window after handover.

• NDA friendly

  Clients are named in case studies only where they agreed. Otherwise specifics are anonymized.

• What does Your Private Dev build?

  Your Private Dev builds workflow automation, AI agents, integrations and custom internal tools for the operations and finance teams of established small and mid-size businesses, plus MVP development when you need a first version. Shipped examples include an invoicing agent on Business Central, a Brightpearl and HubSpot sync, annual report generation, HubSpot CRM cards and chat-driven operations for a roofing contractor.

• Which back-office work is worth automating first?

  Start with work your team repeats every week and where the workflow return is clear. At Kintec that was contractor invoicing, 70+ hours a month of reading emails, checking Business Central and finalizing invoices. At Distinguished Clubs it was annual member-club reports, 250+ hours a year of mail-merge and layout fixes. If no process exists yet, the work is not ready to automate.

• Can an AI agent finish a task without a person?

  In the Kintec build, yes for standard invoice cycles. Contractors email a request, and the agent parses it, cross-verifies it against Business Central, generates the invoice, validates it against accounting rules and historical patterns, and finalizes the payment workflow with no human in the loop. It is a poor fit when there is no clear workflow return or the goal is AI for marketing hype only.

• How do you connect systems that do not talk to each other?

  By building the integration they lack. For Aid Through Trade, a two-way sync keeps Brightpearl and HubSpot in step, in real time from HubSpot and daily from Brightpearl. For DeMont, whose iClassPro had no API the school could use, a scheduled service signs in, pulls the reports and syncs linked records into HubSpot. Each build has its own case study.

• What results have the builds delivered?

  The figures are on the case pages. Kintec: 70+ hours a month of invoicing removed. Distinguished Clubs: 250+ hours a year of report production removed. Code Ninjas: 797 franchise locations on one booking platform. Aid Through Trade: 10,399 Brightpearl contacts migrated into HubSpot. CrossLogic: an 83,000-page federal case extracted at about $0.003 per page in AI cost. Every number is taken from the case study it belongs to, and each case page lists the stack and the steps behind it.

• What happens on the first call?

  The first call is a 15-minute scoping call with direct questions about your goal and your constraints. You then get a written quote with fixed scope, timeline and deliverables, within 48 hours and before any code is written. If the project turns out to be a poor fit, for example because the scope is undefined or an off-the-shelf tool already solves the problem, that comes out in the call.
