Usama I.

Top Rated on Upwork. I design and deliver cloud and Microsoft 365 migration, multi-cloud architecture, disaster recovery, SOC 2 and ISO 27001 readiness, ERP and data integration and AI platforms for organizations where downtime, data loss or an audit finding carries real cost. You get one accountable senior architect from design through handover. I make the design decisions, build or direct the work, and document it so your team can run it without me. Work starts at the level you need: a paid assessment, an architecture or consultation engagement, or full execution. WHERE I CAN HELP Cloud and tenant migration Planned moves between Microsoft 365 and Google Workspace tenants, tenant-to-tenant consolidation and on-premises to Azure, with Entra ID, mail flow, permissions, rollback criteria, validation at each stage and a user communication plan. Delivered: a tenant-to-tenant consolidation of 1,266 users with no data loss, no structural loss and no downtime, and a 380-user cross-platform cutover for a Saudi Arabian enterprise that preserved identity and mail. Multi-cloud architecture and infrastructure as code AWS, Azure and Google Cloud designs built with Terraform and Kubernetes, covering environments, networking, identity and CI/CD, with cost governance so the platform stays manageable after launch. Disaster recovery and resilience Recovery designs set against agreed RTO and RPO targets, with failover runbooks, backup posture and test plans a business owner can approve. Identity, access and Zero Trust Entra ID, Okta, SSO through SAML and OIDC, MFA, Conditional Access and federation, including access gateway design for legacy ERP systems. SOC 2 and ISO 27001 readiness Gap assessment, control mapping, policy and evidence structure, security questionnaires and a remediation roadmap, so an audit starts from a documented position. ERP, CRM and systems integration Architecture and integration across Salesforce, SAP, Oracle, PeopleSoft, Microsoft Dynamics 365, Odoo and ERPNext, covering single sign-on, data flows and API work between systems. Backed by 17 years of hands-on API work, including AppFolio, Zoho and Freshdesk integrations built around each client's business case. Data warehouse, analytics and AI Data warehouse and ETL design on Snowflake and Databricks, GA4 analytics setup and production AI: model hosting, retrieval-augmented generation (RAG), MLOps, access control, monitoring and cost limits, held to the same security bar as the rest of your environment. HOW THE WORK RUNS Every engagement starts with a written scope that names assumptions, risks, acceptance criteria and rollback conditions before anything changes in production. Assessments are fixed fee and state the cost and revenue case for the change, so the decision can be approved on numbers. Larger builds are quoted at a fixed price once the assessment is done. Work moves through discovery, design, implementation and handover, and ends with documentation your team can operate from. Migrations include seven days of post-cutover support. Contracts run through Upwork, and NDA, SLA and data processing terms are available on request. BACKGROUND Infrastructure and architecture work since 2008 and direct US and international client work since 2014, including Fortune 500 and NYSE-listed environments under partner engagements, subject to client confidentiality. Hire me directly, or contract my agency Expandware on Upwork when you need a delivery team. Credentials include AWS Partner accreditations and Google Workspace Administrator. TO START Tell me: - The problem or issue you need solved - The deadline behind it - Your current environment and target platform: cloud, tenant, ERP or data stack - Any audit or compliance obligations that apply I will reply with the right first step: an assessment, an architecture engagement, a migration plan or an implementation. Where scope is uncertain I recommend a short paid discovery phase first, because it fixes scope and risk before production changes begin.
