Clément Sauvage · Bits’n Coffee
Senior judgment for consequential iOS decisions.
Clément Sauvage is a French senior iOS consultant and product engineer based in Lille. Since 2008, he has helped teams make and implement consequential decisions about native Apple products. Companies hire him when an iOS codebase, roadmap or delivery organization needs experienced diagnosis, architecture, modernization, mentoring or hands-on technical leadership. He works with founders, CTOs, product leaders and engineering teams at startups, scale-ups and larger companies, remotely across France, Europe, the United Kingdom and the United States. Bits’n Coffee is the product engineering studio founded and led by Clément. Clients work directly with him, while trusted specialists can join when an engagement requires additional expertise.
When to bring me in
Where evidence changes the decision.
Hire an iOS consultant when the cost of an unclear decision is greater than the cost of getting senior evidence early.
What does your iOS team need?
Architecture is slowing product work
Review boundaries, dependencies, state and data flows, testing and ownership to find the few changes that will restore delivery leverage.
A roadmap depends on a technical choice
Evaluate options against product value, team capability, time, operating risk and the existing system before committing to a direction.
Your iOS team needs a senior counterpart
Provide architecture review, mentoring, code-level support and decision facilitation while strengthening the team rather than replacing it.
A release or migration is at risk
Separate symptoms from root causes, define a recovery sequence and take hands-on ownership of the highest-risk work.
Consulting capabilities
From diagnosis to a shippable next move.
Consulting can be a focused intervention, an audit with deliverables, or an ongoing senior role alongside the existing team.
Architecture
Review or define an iOS architecture that supports the product roadmap, quality expectations and the people maintaining it.
Technical audits
A structured review of maintainability, performance, dependencies, release practices, security considerations and accessibility.
Modernization strategy
Decide what to modernize, in what order, and which working parts should remain untouched.
Product and delivery leadership
Connect technical choices to product priorities, scope, milestones and a credible release path.
Mentoring and team enablement
Improve review quality, shared practices and the team’s ability to make future Apple-platform decisions.
Hands-on rescue
Move from diagnosis into implementation when the highest-value outcome is getting the product shipping again.
Relevant work
Decisions tested in production.
Selected Apple-platform work where architecture, product judgment and delivery had to remain connected.

Approach
Evidence, decision, execution
The format changes with the engagement, but the work always produces an understandable decision and a practical next move.
- 01Inspect
Build a shared picture
Review the product, code, release system, roadmap and team context instead of diagnosing architecture in isolation.
- 02Decide
Make trade-offs explicit
Rank issues by product impact and risk, document options and recommend a sequence with clear reasoning.
- 03Enable
Leave the team stronger
Implement critical work, support the team and transfer enough context that the recommendation remains useful after the engagement.
Frequently asked questions
Clarity before commitment.
The engagement should produce evidence, an understandable decision and a next move the team can own.
What is the difference between an iOS consultant and an iOS developer?
A developer is primarily responsible for implementation. A consultant is brought in to diagnose, frame decisions and guide architecture or delivery. Clément can combine both roles when advice also needs hands-on execution.
Can an iOS consulting engagement be short?
Yes. A focused audit or decision workshop can be bounded, while rescue, modernization and fractional leadership usually continue through implementation.
Will an audit automatically recommend a rewrite?
No. The recommendation may be to keep, repair, refactor, modernize incrementally or rebuild specific parts. The decision follows evidence and business value.
Can Clément work with an existing engineering team?
Yes. Consulting commonly happens alongside internal developers, product leaders, agencies or other specialists.
Bring the iOS decision.
Leave with a credible next move.
Share the product, codebase, team and decision in front of you. I’ll personally review the context and tell you where a focused consulting engagement can create leverage.
