Full career history
Mehdi Singer
Senior IT Technician
Systems-minded engineer with 15+ years in IT who turns operational problems into reliable, automated, auditable systems. I design and build the internal platforms organisations run on — device-lifecycle and MDM pipelines, deployment automation with queuing, retry logic and audit logging, network segmentation, and internal web tooling. Python/Django builder currently developing an agent-first SaaS platform, with hands-on work designing multi-agent verification workflows. Proven at scale: a deployment pipeline I designed delivered 6,000+ devices for the UK General Election with zero critical failures.
01 / Core strengths
What I bring to a technology operations team.
Reliable automation
Queuing, retry logic, per-device status tracking, secure logging, role-based access, audit trails.
Build
Python, Django, Flask, PostgreSQL; internal web tooling and API-driven workflows.
AI workflow design
Multi-agent orchestration with separation of duties and independent verification; human-in-the-loop.
Infrastructure
Network segmentation, backup architecture, failure-mode design, consolidation of fragmented systems.
02 / Experience
Every role, in full.
2021 - Present
Senior IT — Systems, Automation & Device Lifecycle
Hire Intelligence International
Designing and building the internal systems that move device deployment, asset recovery, and infrastructure from manual to automated and auditable.
- Designed a staged device-deployment pipeline — queued enrolment, retry logic, per-device status tracking, role-based access, secure logging — scaling throughput from ~400–500 to 1,000+ devices per month.
- Delivered 6,000+ devices for the UK General Election across Windows, macOS, iOS, Android, and VR with zero critical failures.
- Consolidated three MDM platforms into one (Miradore), segmented the network, and built an end-to-end asset-recovery system that recovered £60k+ of tracked damages in year one.
- Engineered security and observability into the platform: secrets never written to logs, layered access permissions, and a full audited change history.
- Redesigned network topology to isolate the imaging and WDS network from corporate traffic.
- Re-architected company infrastructure: segmented the technical, office and phone networks, and automated backups across three locations to remove single points of failure.
- Integrated AI into operational workflows with human review — script and snippet generation, document summarisation, and an email-triage automation that verifies the sender domain and routes summarised leads to the sales pool.
- Built internal web applications (Python/Flask, SQLite, HTML/JS/CSS) for asset management and workflow automation; mentored and trained junior technicians.
2019 - Present
Founder & Director — Private Technology Systems
Central Technologies Limited
End-to-end technology environments for private clients: system architecture, network security, device management, and reliability.
- Design and run complete technology environments — architecture, security, backups, and ongoing reliability.
- Retained long term for technical competence, judgement, and discretion.
2013 - 2021
IT Technician / Field Engineer
Computer Doctors Lab Ltd
Rebuilt and scaled networks for growing SMEs under time and budget pressure, across enterprise, retail, and private-client environments.
- Diagnosed needs from incomplete information and delivered working systems fast; 99%+ success rate.
- Supported clients including Christian Louboutin, Sky B2B, Burberry, and Harvey Nichols.
2003 - 2013
Infrastructure Technician to Infrastructure Lead
Earlier roles — London & Iran
Progressed from hardware technician to infrastructure lead, digitising operations and designing networks across multiple organisations.
- Designed and built networks for organisations moving from paper-based to digital operations.
- Progressed from hardware support into infrastructure ownership and technical leadership.
03 / Selected projects
Systems I designed and built.
UK General Election — Device Deployment Platform
ProjectMDM · multi-platform · queued pipeline with retry & audit
Designed a staged pipeline with queued enrolment, retry logic, status tracking, role-based access, and audit logging — delivering 6,000+ devices for the UK General Election with zero critical failures.
Read the case studyMulti-Agent Verification Workflow
ProjectMulti-model orchestration · Markdown-defined agent specs
Designed a workflow where separate agents plan, execute, and independently verify each task in a loop — with automated web-based verification, built around separation of duties so model output is never treated as authority.
Asset Recovery System
ProjectPython · workflow automation · finance reporting
Built an end-to-end system — technician form with database lookup and evidence capture, approval routing, automated comms, and finance reporting with a full audit trail. Recovered £60k+ of tracked damages in year one.
SME Workflow Automation Platform (working title)
In progressPython · Django · PostgreSQL · Tailwind · agent-first architecture
Designing an agent-first platform for SME office management: routine admin, internal requests, documents, expenses, appointments, and task management.
