Team Lead – Information Technology Operations · Data Protection Officer

Nairobi Club

Aug 2026 – Present

Lead ICT operations for Nairobi Club, a multi-department private members' and hospitality organisation, with responsibility spanning infrastructure, cybersecurity, business systems, service continuity, vendors and data protection.

  • Lead day-to-day technology operations across Windows Server and Active Directory, Microsoft 365, LAN/Wi-Fi, endpoints, access control, user support and the core systems used by Finance, Membership, Procurement, Food & Beverage, Front Office and Administration.
  • Set priorities across incidents, service requests and improvement work; coordinate internal technical resources, department users and external vendors so urgent operational issues are resolved without losing momentum on longer-term projects.
  • Own cybersecurity improvement and audit-remediation work, including Check Point firewall controls, Kaspersky Security Center, endpoint hardening, access reviews, vulnerability follow-up, evidence collection and closure of internal-audit actions.
  • Lead resilience work around backups, disaster recovery, business-continuity planning and redundant connectivity, including the Club's secondary internet-link programme.
  • Serve as the designated Data Protection Officer, coordinating privacy and compliance work, reviewing data-handling risks and ensuring new systems and vendor arrangements consider data-protection requirements.
  • Prepare technical and commercial papers for CFO, CEO, ICT Subcommittee and Board decisions, translating infrastructure, telephony, security, systems and vendor proposals into clear options, risks and recommendations.
  • Lead the architecture and delivery of ClubOne, the Club's in-house ERP, including shared identity, role-based permissions, maker-checker controls, audit trails and modules across procurement, HR, finance, membership, POS, inventory, hospitality and reporting.
  • Review technology contracts, support arrangements and SLAs, and manage relationships with connectivity, security, printing, telephony, access-control and business-system vendors.

Tech Lead & Enterprise Systems Engineer

EkvatorSnus Ltd

Mar 2026 – Present

Lead enterprise systems and infrastructure work for EkvatorSnus, combining hands-on software engineering with responsibility for the Microsoft environment supporting the Kenya and Sweden teams.

  • Architect and develop the company's operational platform for manufacturing, inventory, purchasing, sales orders, pricing, trade documents, tax workflows, reporting and field activity.
  • Design business rules around production batches, inventory movements, order processing and financial-sensitive workflows so stock and commercial records remain internally consistent.
  • Strengthen application security through request-integrity checks, permission enforcement, rate limiting, guarded write paths, auditability and safer handling of cross-market pricing and inventory references.
  • Implement database-transaction and concurrency controls for multi-step manufacturing and sales operations, including safe batch creation, cancellation boundaries and integrity constraints.
  • Manage application releases and production changes across Next.js, Prisma, PostgreSQL/Neon and Vercel, with testing and migration checks before changes reach users.
  • Administer Windows Server, Microsoft 365, Exchange Online, Active Directory, Group Policy, DNS and DHCP, and troubleshoot issues that cross the boundary between infrastructure and application services.
  • Coordinate technical changes between the Kenya and Sweden teams so user access, infrastructure changes and application releases stay aligned with operational needs.

IT Systems Administrator

Nairobi Club

Feb 2025 – Jul 2026

Administered the Club's Microsoft environment, network services, endpoints and business applications, providing the hands-on operational foundation that later grew into my current team-lead remit.

  • Administered Active Directory, Microsoft 365 and Windows environments, including user lifecycle, access permissions, workstation configuration and Group Policy-related administration.
  • Maintained LAN and Wi-Fi services, DNS, DHCP, TCP/IP connectivity and secure access across Club offices, receptions and operational areas.
  • Managed workstation deployment, endpoint troubleshooting, hardware lifecycle, printers and day-to-day user support for staff across multiple departments.
  • Supported the ERP/POS and departmental applications used by Finance, Membership, Procurement, Food & Beverage, Administration, Front Office and accommodation operations.
  • Supported endpoint and network-security improvements, including Kaspersky Security Center administration, access reviews, hardening work and follow-up on technology audit items.
  • Supported HikVision-based access-control and attendance operations and coordinated technical issues with vendors where systems crossed physical-security and ICT boundaries.
  • Documented recurring issues, system configurations and operational dependencies, and contributed requirements and technical context to later systems-modernisation work.

Software Developer & Systems Consultant

BiBiBiU Technologies

Apr 2025 – Mar 2026

Delivered client web applications and business systems end to end, working directly from requirements and process discovery through implementation, deployment and post-launch support.

  • Worked with clients to turn business requirements into practical application flows, data structures and delivery plans rather than beginning from a fixed technical brief.
  • Built and maintained responsive web applications and business systems using modern JavaScript/TypeScript stacks, APIs and database-backed workflows where required.
  • Handled deployment, hosting configuration, domains, DNS, SSL and production cutovers, including troubleshooting issues that appeared only after systems went live.
  • Maintained existing applications, shipped requested changes and resolved production defects instead of treating launch as the end of the engagement.
  • Explained technical trade-offs to non-technical clients and kept project scope, implementation detail and operational expectations aligned throughout delivery.

Cybersecurity Intern & Systems Analyst

Prosecution Training Institute · Government of Kenya (ODPP)

May 2024 – Aug 2024

Supported systems and cybersecurity work at the Prosecution Training Institute while completing a practical internal application project for asset management.

  • Assisted with security monitoring, vulnerability assessment and system reviews, documenting findings and supporting follow-up within a government technology environment.
  • Supported workstation, application and connectivity troubleshooting for users and assisted with routine systems administration and technical documentation.
  • Reviewed asset-tracking needs with users and built a Laravel-based asset-management system for the Institute.
  • Designed the asset application's data structure and operational flows around recording, locating and maintaining equipment information more consistently than the existing manual process.
  • Worked within public-sector access, documentation and change-control expectations while balancing internship learning objectives with useful production-oriented work.

Senior Systems & Solutions Engineer

Surety PR & Media

Jan 2023 – Mar 2025

Owned technical delivery for client websites and digital platforms at a communications agency, covering the visible product as well as the hosting, domain and production work behind it.

  • Gathered client requirements and translated brand, content and business objectives into websites and digital experiences that could be maintained after launch.
  • Built, launched and maintained client websites and digital platforms across multiple projects, including redesigns and later production iterations.
  • Managed domains, DNS, SSL, hosting environments and production deployments, and diagnosed availability or configuration issues when they occurred.
  • Handled CMS administration, content changes, analytics/data work and ongoing technical support for live client properties.
  • Worked directly with strategy, creative and client-facing teams so technical implementation supported the wider communications objective rather than operating as a separate workstream.
  • Supported security, performance and maintenance improvements across production websites as client requirements and hosting environments changed.

Systems Support & Cybersecurity Analyst

Givewatts International

Mar 2020 – Dec 2024

Supported staff, internal technology and public digital platforms for an international development organisation, building the broad support and systems foundation I later carried into infrastructure and security roles.

  • Provided day-to-day technical support across hardware, software, user accounts and business systems for teams working across Kenya and international operations.
  • Maintained and updated the Givewatts web platforms, including public campaign, impact and donor-facing content across the organisation's international and East Africa sites.
  • Supported CMS administration, web publishing, website changes and data/analytics work for communications and operational teams.
  • Worked on infrastructure improvements and security hardening, including account/access hygiene, domains, SSL and the operational upkeep needed to keep public services available.
  • Troubleshot recurring user and system issues, documented fixes and supported staff with practical guidance rather than relying on repeated ad-hoc intervention.
  • Worked across technical and non-technical teams, learning to explain technology in terms of the work it enabled rather than only the underlying tools.
