Engineering & technical leadership
Independent engineering / BelgiumBuilt a working prototype with AI? Blacksquare Labs helps turn it into reliable software that can grow with your business. Get the architecture, engineering and technical leadership to move beyond the demo.
01 Beyond the prototype
AI tools helped you move fast. Now changes break other features, the code is hard to follow, or nobody knows which parts to trust. Get the architecture reviewed, fragile code reworked and critical behavior covered by tests.
Move beyond the happy path. Put access controls, reliable data handling, deployment and monitoring in place. Test how the application behaves as usage grows, and fix the bottlenecks.
Get a technical partner to assess tradeoffs, choose an architecture and plan the next releases. Work through what to keep, what to rebuild and where to invest as the product grows.
02 Example project
Follow a support assistant from its first prototype through testing, connection to a ticketing system and release. The video illustrates the work involved.
03 Code, data and access
I work in your repositories and use your hosting and service accounts. Changes go through your team’s review process. Before connecting a model to your data, we agree what it may access and where that data will be processed.
04 Project deliverables
Improvements to the existing code and architecture, with tests for the workflows your users depend on. Changes stay in your repository and can be reviewed as the work progresses.
Configuration for your hosting environment, logs to investigate problems, and instructions for releasing updates or restoring the previous version.
A walkthrough of the code, connected services and known limitations, so your team can run the application and continue developing it.
05 Technical review
Get a clear view of the code behind your prototype: where the architecture is fragile, what could fail under load, and what needs work before launch. Leave with priorities for the next stage of development.
See the technical review06 Working arrangements
Turn the code you already have into a product you can release, maintain and grow.
Get CTO-level guidance on architecture, engineering priorities and future development, with hands-on help to put decisions into practice.
For agencies: Take a client prototype into production.
For agencies07 Working together
Blacksquare Labs is an independent engineering practice based in Brussels.
You work directly with an engineer who can assess the architecture, make changes in the code and help plan what comes next. That can mean working alongside your developers or providing technical direction when you do not yet have a technical lead.
About Blacksquare Labs08 Questions
Taking prototypes into production, improving code and architecture, and providing ongoing technical leadership. The work covers both the software and the decisions about what to build next.
Written findings, issues ranked by importance, a test plan and estimates for the recommended changes. We discuss the findings together. Your team can make the changes, or bring me in to implement them.
Yes. Bring the code you have. The first step is to understand how it works, keep what is useful and identify what needs fixing or replacing. You do not need to start again by default.
You work directly with me on the code, tests and technical decisions.
Yes. Work can stay in your code repositories, infrastructure and accounts. We agree where data is stored, which providers are used and who has access before development.
An agent can use only the data and tools approved for its task. Application code checks permissions and inputs. Actions such as sending information or changing records can require human approval. Instructions to the model do not replace these checks.
The application can show sources, decline a request or ask a person to review an action. These behaviors are tested, and new failures become test cases.
Yes. We can test your idea with a prototype. A Technical Review is useful when there is already code to inspect.
