Khaleel Sethi

A certified Business Analyst with 22+ years of IT infrastructure, networking, and security experience. Holder of the TOGAF 10 Enterprise Architecture Foundation & Practitioner and BCS Foundation Certificate in Business Analysis, with the BCS Practitioner Certificate in progress. Throughout a technical career spanning pre-sales consultancy, client-facing discovery, and complex infrastructure delivery, I have consistently operated at the intersection of business and technology — eliciting requirements, running structured discovery sessions and design reviews, translating stakeholder needs into clear technical solutions, and producing structured documentation including HLD, LLD, and Statements of Work.

I bring rare credibility in both business and technical conversations and am now applying formal BA methods to technology-led change programmes. I am seeking hybrid or remote BA roles across Manchester and the wider Northwest, where I can help deliver outcomes that are practical, secure, and operationally sound.

• Reshaped LAN/WAN proposals during discovery after surfacing scope assumptions the client team had not validated, avoiding downstream rework and protecting deliverability against committed timelines.
• Challenged engineering effort estimates on a multi-site datacentre SoW where the proposed phasing did not reconcile with the resilience requirements; reworked the approach with the delivery lead before commitment.
• Identified a Wi-Fi coverage assumption during discovery that would have compromised the client's post-deployment user experience target; flagged early and reshaped scope before SoW finalisation.
• Designed and delivered PoC engagements for Cisco and Juniper solutions, translating requirements into testable outcomes and presenting results to technical and non-technical audiences.

• Designed and delivered PoC environments for Cisco ISE and Cisco 9800 wireless controllers, translating complex requirements into clear, demonstrable outcomes.
• Validated Palo Alto firewall solutions against security and operational requirements, presenting findings to support client decision-making.
