Architecture and system design reviews
An assessment of how your system is structured, where it will struggle as you grow, and the changes that give the most benefit for the effort.
Consulting and Strategy
Software consulting, architecture reviews and code audits
Senior, independent technical advice drawn from years of shipping and rescuing products: architecture, code and security reviews, delivery planning, and roadmaps leadership can budget against.
Sometimes what a business needs is not more code but a clear answer. Is this architecture going to hold? Is the codebase we are about to buy in good shape? Why has our product stopped shipping? We give that answer in writing, based on the code and the facts, from people who build and rescue products every week.
Our reviews cover architecture, code quality, security and performance, and end with a prioritised list of what to fix, what to leave and what it will cost. For founders and leadership teams we turn product plans into roadmaps and estimates you can budget against.
A growing share of our work is rescuing projects started with AI coding tools such as Lovable, Bolt and Replit. We assess what is worth keeping, fix security gaps and set the project on a path to a real launch.
What is included
Code, security and performance audits
A review of code quality, test coverage, dependencies, access control and performance, with findings ranked by risk.
Technical due diligence
An independent report on a product's technology for investors or buyers, covering quality, risks, team practices and the cost of fixing what is found.
Roadmaps, estimates and team planning
Product plans turned into phased roadmaps with estimates, plus advice on the roles and skills needed to deliver them.
Recovery of stalled or AI-generated codebases (Lovable, Bolt, Replit)
Prototypes and stalled projects brought to a launchable state: security fixed, structure cleaned up and deployment set up properly.
How we work
- 01

- 02
Review
Senior engineers review the code and systems, and talk to your team where that adds context.
- 03
Written report
Findings ranked by risk and impact, each with a recommended action and rough effort.
- 04
Walkthrough and next steps
A call to go through the report, answer questions and, if you want, plan the fixes with us or your own team.
Tech stack
- System design
- Code audits
- Security reviews
- Due diligence
- Roadmaps
Pricing
Every project starts with a free discovery call and a written estimate split into milestones. Choose the model that fits:
- Fixed-price project. A written scope split into milestones, each with a fixed price and deliverable. Best when requirements are clear.
- Hourly. Pay for the hours worked, with time tracked and reported. Best for ongoing changes, audits and evolving scope.
- Dedicated developer or team. Developers assigned to you on a monthly contract, working your business hours as an extension of your team.
- Maintenance and support. 24/7 monitoring against a 99.9% uptime target, plus fixes, updates and small features after launch, as needed or on a monthly plan.
FAQ
Consulting and Strategy questions
What clients usually ask before starting a consulting and strategy project with us.
Another question? Email info@mercurysols.org.
What do we get at the end of a review?
A written report with findings ranked by risk, the reasoning behind each, recommended actions and rough effort estimates, followed by a call to walk through it.
Will you sign an NDA before seeing our code?
Yes. We regularly sign NDAs before reviewing confidential code or documents, and only need read access.
Do we have to hire you to fix what you find?
No. The report is written so any capable team can act on it. If you want us to do the work, we will quote it separately.
Can you rescue an app built with Lovable, Bolt or Replit?
Yes. We check what can be kept, fix exposed keys and weak authentication, restructure the code where needed and set up proper hosting, or recommend a rebuild if that is faster.
Can you help with technical due diligence for an investment?
Yes. We review the product's code, architecture, security and delivery practices and report on risks and the likely cost of addressing them.
