03 — The JBKR Method

From problem to continuous operation, with scope and success metrics defined before any code is written

01

Discovery

We map the problem, the systems involved and the data available. You get a scope, success metrics and an honest estimate.

typically 1–2 weeks
02

Proof of concept

We build the smallest version that proves the value — one workflow, one integration, one chatbot over your real documents — before any large commitment.

typically 2–4 weeks
03

Production

We evolve the PoC into production with security, guardrails, tests and telemetry. Nothing ships without a measurable quality bar.

scope-dependent
04

Continuous operation

Ongoing support under the monthly plans: monitoring, data-driven improvements and fast response when something changes — including in your legacy systems.

What our clients have to say

Their experiences are our greatest motivation

Carlos M.

Rubens B.

Hybrid App

Simply perfect! I was very lucky to choose him for the job. Very intelligent, understands the requirements very easily, and executes with precision and speed. If you are building an app, have him on your team. He was very fair with the price and completely honest in assessing his own work. On his own initiative he even did more than was needed, because he later judged that what I had paid was a lot for the job. Fair, patient, good-natured, intelligent, competent and very, very professional. I highly recommend him! There may be someone just as good, but better — I find that hard to believe.
