A second opinion from a firm that builds and tests systems itself

Technology choices, vendor evaluation, product planning and project rescue — an engineer's advice, not a slide deck.

Technology decisions are the hardest ones to undo: the wrong vendor, an over-engineered architecture or a product built without analysis can cost months of work and a large slice of the budget. Companies without their own CTO risk the most — their only “second opinion” is the view of a supplier who profits from a particular answer.

We advise on the client's side of the table and from practice: we read the code, the offers and the estimates, ask vendors the questions that need answering, and translate technology into business terms. You don't get an opinion out of thin air — you get a recommendation in writing, with the reasoning, including when it says “don't build this”.

This is not slide-deck consulting. Day to day we design, build and test systems, so we only recommend solutions we could implement and maintain ourselves. You get the recommendation in writing, with the reasoning and the cost of every option considered — including the one that says change nothing for another year.

What the service covers

  • Technology selection and architecture

    You choose the technology knowing exactly why: we match the stack and design the architecture around real constraints — scale, budget, the team's skills — rather than whatever is fashionable. We also advise on infrastructure planning and cloud migrations.

    • Technology stack selection for the project and team
    • Architecture consulting and design reviews
    • Infrastructure and cloud migration planning
    • A modernisation plan for an existing system
  • Product planning and project analysis

    Before a project gets a budget, you know exactly what will be built: we prepare a technical analysis of the idea, an MVP scope, development stages and risks, and documentation that lets vendors submit offers you can actually compare.

    • Technical analysis of an idea before budgeting
    • MVP scope and a staged development plan
    • Specifications and technical documentation for vendors
    • Analysis of project risks and assumptions
  • Vendor and proposal evaluation

    You sign knowing what you're actually buying: we give proposals, estimates and contracts an independent technical read — what the vendor is really promising, what's missing from the offer, which items look inflated and what to ask before signing.

  • Project rescue

    When a project is stuck, we start with a diagnosis: the actual state of the code and scope, how much of the progress reporting holds up, and what can be saved. Then you get a way out — repair, a vendor change or a controlled shutdown — with the realistic cost of each path.

  • Supporting development and QA teams

    Your team gains an experienced pair of eyes without hiring a senior for a full-time seat: code and architecture reviews, tightening up the development and testing process, mentoring, and support on demand when it's needed.

Typical situations

  • You have several offers for the same project on the table, prices apart by a multiple, and no way to tell which to trust.

  • The “three-month” project is a year in, and the vendor has a good explanation every time.

  • You're planning a product and want a realistic view of cost and risk before making commitments to investors or the bank.

  • The company has outgrown its current system, and no one inside knows whether to modernise it or rebuild.

What you can count on

  • Written recommendations with the reasoning and consequences of each option, not a deck of generalities.
  • Decisions grounded in analysis of code, offers and documents, not the afterglow of a good sales meeting.
  • Advisory work on your side of the table: tied to no supplier and paid for a straight answer, not for selling a build.
  • The knowledge stays with your company: documentation, analysis notes and an action plan you can take to any team.

Questions about this service

It's the most common scenario, and exactly what we're here for: we turn technology into decisions — what to choose, roughly what it should cost, where the risks are and how to tell early that something is going wrong. We translate jargon into specifics, and everything we agree on reaches you in writing, in plain language.

We advise only on the client's side of the table and we're tied to no supplier. If during the analysis we conclude we could deliver a given piece of work ourselves, we say so openly — and the decision stays with you, because the recommendations and documents are yours and you can take them anywhere.

We start with a diagnosis, not promises: we review the code, the repository, the issue tracker and the correspondence with the vendor so far, then lay out the situation with the possible paths — repair, handover to another team, or a controlled shutdown. Diagnosis first, costs second — only with that full picture in front of you do you decide on next steps and budget.

We keep it flexible: from a single consultation, through an analysis with a fixed scope and price, to ongoing advisory work alongside product development. We work remotely with companies across Poland, and in and around Bydgoszcz we can meet in person.

Related services

  • Technical audits

    Audits of code, applications, websites, QA processes and infrastructure. Instead of opinions and reassurances, a written report with priorities and an action plan.

  • Software development

    Software written for a specific problem: internal systems, MVPs, integrations and taking over an application from another vendor — designed around how your company works, not the other way round.

  • DevOps and cloud

    CI/CD, Docker, Terraform and AWS, so releases become a single click and you hear about failures before your customers do.
