About Hamza

Consultant RPA / Hyperautomation (UiPath, Power Automate) – Python / C# / SQL

Automation engineer specialized in UiPath, I work on the entire lifecycle: scoping, design, development, testing, deployment, and run (support, incidents, optimization). Accustomed to regulated environments and high-volume processing, I deliver robust, traceable, and maintainable automations with measurable ROI (reduction in delays, errors, and manual tasks).

What I do:
• UiPath: Studio, REFramework, Orchestrator (queues, triggers, assets, schedules), incident recovery, parallelization, logs, and retry.
• Power Automate: cloud flows, M365 integrations, "business ready" rapid automations.
• Dev & data: Python/C# (tools, API clients, reusable frameworks), SQL Server/PostgreSQL (quality checks, queries, light ETL), reporting (Excel/Power Query, Power BI).
• Applied AI (as needed): OCR/NLP/RAG for documents and unstructured data, with business validation.

My method:

1) Rapid diagnosis (process, volumes, risks) 2) Design (PDD/SDD, scenarios, exceptions) 3) Iterative build with demos 4) Scoped UAT 5) Go-live + hypercare, runbook, and knowledge transfer.

Available for: end-to-end RPA development, industrialization/standardization, stabilization of a production environment, document automation, API & data integrations.

    • AI-Augmented Automation: NLP/OCR integration (Azure Cognitive Services + Python models: spaCy / scikit-learn) to classify/extract data, apply business rules, and ensure traceability/auditing (SQL).

    • Reusable Framework: Implementation of a C#/Python foundation (ingestion, validation, logging, retry, REST calls) reused across multiple projects (AS400/API/SQL).
    • Monitoring & Reporting: ETL orchestration (C#/Python) to PostgreSQL + Power BI / Excel dashboards (Power Query) for monitoring volumes, exceptions, SLAs, ROI; automated refresh and distribution.
