As a Top-Rated freelancer, I’m ready to help you manage IT systems, support your customers, and build or maintain websites that meet your business goals.

AWS environments designed, deployed, and sustained. Microsoft Intune programmes built. Microsoft 365 tenants migrated. Long-term Senior Cloud Engineer engagements or finite implementation projects — I run both. 8 years on Upwork: 100% Job Success, Top Rated Plus, 11,233 hours, $400K+ earned across 35 contracts. I work with MSPs, MSSPs, and tech-mature SMBs in two patterns. Pattern one: embedded long-term Senior Cloud Engineer — I become a stable hand on your environment, the way I spent 8 years on a 168-server hybrid AWS estate. Pattern two: finite implementation projects — scope, design, deploy, validate, hand over. Both work without ramp-up. Both work without supervision. Recent reference points: - 8 years as Senior Cloud Engineer on a 168-server hybrid AWS estate (Linux + Windows) for an ASX-listed catering enterprise — CrowdStrike deployment, Oracle E-Business DR build, documented India offshore transition. December 2017 through January 2025, unbroken. - Microsoft Intune + Apple Business Manager rollouts at NWCR (Chicago MSP) — conditional access framework, Autopilot, mixed Apple/Windows fleet. - Amazon WorkSpaces and AppStream 2.0 builds at Syncronet (Houston) — application catalogues, directory integration. - Before Upwork: founded and ran my own MSP (ITRS), scaled to R5m revenue, Microsoft Silver Infrastructure Partner. Before that, Regional IT Manager at Discovery Holdings — 99.8% uptime across regulated financial services. What I deliver: - AWS cloud migrations, implementations, and ongoing operations — EC2, S3, RDS, Lambda, WorkSpaces, AppStream. Well-architected design, lift-and-shift, hybrid estates. AWS Certified Solutions Architect — Associate (verified by Upwork). - Microsoft Intune endpoint rollouts and lifecycle management — Autopilot, conditional access, configuration profiles, Apple Business Manager, BYOD/COPE programmes. - Microsoft 365, Azure, Entra ID migrations and tenant work — tenant moves, Exchange Online, SharePoint, Teams, Purview, security baselines. - MSP toolchain implementation and ongoing optimisation — Kaseya, N-Central, ConnectWise PSA + Automate, NinjaOne, IT Glue. I built my own MSP from zero, so I can architect or operate yours the same way. How engagements run: for finite projects, scope to design to deploy to validate to hand over. For long-term retainer or embedded work, weekly reporting cadence, monthly DR and security review, documented incident history. Either way, every change documented — I built the runbooks that let an India offshore team take over the AWS estate after 8 years, and I work the same way for new clients. SAST timezone (UTC+2) overlaps EU business hours, US mornings, and AU afternoons. What I don't do: application development, ML model training, or Kubernetes-first DevOps. My lane is cloud infrastructure, endpoint management, and migrations — operations and stability, not greenfield app dev. Credentials: AWS Certified Solutions Architect — Associate · Top Rated Plus · 100% Job Success Score · 11,233 platform hours · 35 completed Upwork contracts · 8 years on Upwork · ITIL Foundation · 30+ years in IT. If you have an AWS migration in scope, a stalled Intune rollout, a tenant move that needs to ship — or a senior cloud engineer slot you need filled long-term — send me the brief. I'll come back within 24 hours with whether I'm a fit and what the first 30 days would look like.

I build production AI systems — working systems that ship to real clients and solve real problems, not prototypes that sit in a sandbox.
