Description

RAMS / Functional Safety and Functional Safety Engineer, I support industrial companies, design offices, integrators, and equipment manufacturers in the design, evaluation, and justification of critical systems.

I have multi-sector experience in rail, Oil & Gas, industrial machinery, and automotive, with a dual perspective: system/hardware/software design on one hand, and independent functional safety assessment on the other.

My background has allowed me to work on on-board and trackside railway systems, safety instrumented functions in Oil & Gas, machinery equipment, as well as electronic and software architectures subject to safety requirements.

I am proficient in the main functional safety and reliability standards: IEC 61508, IEC 61511, EN 50126, EN 50128, EN 50129, IEC 62061, ISO 13849, ISO 26262..

I can undertake one-off or complete missions: document analysis, architecture review, risk analysis, FMEA/AMDEC, FTA/fault trees, PFD/PFH calculations, RAM study on installations, HAZOP/LOPA facilitation, SRS drafting, SIL review, testing assistance, audit preparation, technical file review, or certification support.

Examples of deliverables I can produce:

- RAMS Plan / Safety Plan

- Risk assessment: HAZOP + LOPA

- FMEA / AMDEC / FMEDA (Product, system)

- Fault Trees / FTA

- HIPPS / SIF / Safety Loop Evaluation...

- SIL Report: PFDavg / PFH calculations + architecture review

- RAM study: availability / reliability

- Safety Requirements Specification / SRS

- Requirements traceability matrix

- FMEA / Code critical review

- Document review report

- Evaluation or conformity justification report

- Audit and FAT/iFAT checklists
