IT and cybersecurity consulting offer
When the problem is technical, diagnose before choosing the solution.
IT consulting helps when a system is slow, fragile, insecure or hard to maintain.
I support security audits, performance analysis, distributed architecture, backend, cloud, embedded systems and pre-investment technical reviews.
Good consulting should help you decide whether to fix now, refactor, monitor, replace a component or stop a risky investment. I separate evidence, assumptions and recommendations.
For security and performance work, I consider operational impact, handled data, team responsibility and service continuity. The best solution is the one you can actually maintain.
This is useful even when you already have suppliers or developers: I can act as an independent review, clarify tradeoffs and define technical requirements before changing stack or budget.
Best fit
- Companies evaluating whether a system is secure, scalable or maintainable.
- Teams with backend, database or infrastructure bottlenecks.
- Founders and managers needing a technical review before investment.
Deliverables
- Technical analysis with problems, impact and priorities.
- Recommendations on security, performance, architecture or stack.
- Intervention roadmap with quick wins and key risks.
- Hands-on support for hardening, refactor, deploy or debugging.
- Decision-maker summary: what to do now, what to plan and what to avoid.
- Alignment session to explain technical findings to the people approving budget and priorities.
Risk reduction
- Diagnosis comes before implementation.
- Recommendations are ordered by impact and dependencies.
- I connect code, infrastructure, process and business priorities.
- Evidence is tied to concrete risks such as downtime, data loss, maintenance cost or vulnerabilities.
- Risks are explained in operational language.
Process
One continuous flow from framing to launch: each phase produces decisions and materials for the next.
01
Intake
We collect context, available access, symptoms, constraints and goals.
02
Audit
I review code, configuration, architecture, logs or critical flows.
03
Report
You get prioritized recommendations, not generic best practices.
04
Action
If needed, I move from diagnosis to implementation or team support.
Project formats
The format depends on available access, system criticality, required depth and decision urgency.
Security/performance audit
Deep audit
Deeper review with operational plan.
- OWASP
- performance
- infra
- roadmap
Technical support
Operational support
Hands-on support for refactor, deploy, debug or architecture.
- hands-on
- review
- fix
- handover
Can you sign an NDA?
Yes, when required and reasonable.
Do you need code access?
For deep audits yes; early assessments can start from context and symptoms.
Can you implement fixes?
Yes, I can provide a report or support hardening, refactor, debugging and deploy.
Can you work with an existing team?
Yes, I can support developers or technical managers.
Have a technical doubt blocking a decision?
Send me the context and I will suggest a proportional audit with a clear output.
