Tech Stack Consultant: technology decisions you can justify
Tech stack consulting for new projects and grown PHP and JavaScript systems. You get a recommendation with written reasoning, the trade-offs and a plan to get there.
Why Your Tech Stack Matters
The choice of tech stack is one of the hardest decisions to reverse. A wrong choice shows up later as slow development, scaling problems and developer roles nobody can fill.
As your tech stack consultant, we look at your requirements, your team and your existing code, and compare only the options that actually fit. For existing systems we start from what is already there, because a full rewrite is rarely the cheapest path.
Our technology recommendations are based on your specific requirements, not on hype, trends, or our personal preferences.
Cost of Wrong Choices
When to hire a tech stack consultant
An outside view helps most before a decision is locked in, or when an old decision starts to cost money.
Before a new product or a major rebuild
The stack is still open, and the choice will shape hiring, hosting and delivery speed for years.
When a framework or PHP version reaches end of life
You have to choose between upgrading, moving to another framework or replacing parts of the system.
When the team cannot agree
The discussion goes in circles because personal preferences and actual requirements are mixed up.
When hiring gets hard
Few developers know your stack, and every open role takes months to fill.
When running costs keep rising
Hosting, licence or vendor costs grow faster than the business, and nobody can say whether the architecture is the cause.

What you get from tech stack consulting
Written results your team can work with, not a slide deck of options.
Decision criteria
The criteria the decision is based on, weighted together with you: performance, team skills, hiring market, budget and compliance.
Assessment of the current stack
For existing systems: versions, end-of-life dates, outdated dependencies and the parts that hold you back today.
Options compared
Two or three realistic options scored against the criteria, with advantages, drawbacks and risks for each.
Recommendation with reasoning
A clear recommendation and a written rationale, so the decision stays documented for future team members.
Architecture sketch
How frontend, backend, database and infrastructure fit together in the recommended setup.
Roadmap
Migration or implementation steps in a sensible order, with effort estimates and points where you can stop or change course.
How tech stack consulting works
It starts with a free 30-minute intro call. For existing systems, the assessment of the current stack runs as our Code Readiness Sprint (1 to 2 weeks). The price depends on the scope; you get a concrete quote after the intro call.
Discovery
Understand your business goals, constraints, team and existing systems
Analysis
Evaluate technology options against your criteria
Recommendation
Present detailed stack proposal with trade-offs
Planning
Create implementation roadmap and migration strategy
Support
Guide the implementation, or take it over as interim developers

Common Challenges We Solve
Technology decisions get made under pressure: time pressure, budget pressure, and the pressure of individual developer preferences. These are the situations where an external perspective adds the most value.
"We chose the wrong database and now everything is slow"
Selecting a document database for a workload that is fundamentally relational, or the reverse, is one of the most expensive early-stage mistakes to correct. We help you evaluate data access patterns before you commit, and when the decision has already been made, we map the least disruptive migration path forward.
"We cannot hire anyone who knows our stack"
A framework that was trendy in 2016 or a language chosen because one engineer preferred it can quietly become a hiring liability. We assess your current stack against the European developer market, particularly in Germany, and identify whether a targeted modernization to a more widely-adopted technology is worth the investment.
"The vendor is raising prices and we are locked in"
Proprietary platform dependencies, whether with a PaaS provider, a low-code tool, or a managed service, often only become visible when the vendor changes terms. We evaluate your architecture for lock-in risk, identify which dependencies are genuine constraints and which are just inertia, and help you design toward portability where it matters.
"We are starting fresh and cannot agree on a stack"
New projects often stall on technology decisions because the discussion conflates preference with requirements. We run a structured selection process: define the criteria first, score options against those criteria second, and present the recommendation with full reasoning so the decision is documented and the team can move forward with confidence.
"Our microservices are more complex than the monolith they replaced"
Microservices architecture is frequently adopted because it sounds modern rather than because the specific problems it solves apply to the current situation. The result is distributed complexity without the scale benefits. We help you assess whether your architecture fits your actual team size and traffic patterns, and what a more appropriate structure would look like.
