Angello G.

IBM Certified Python Backend Engineer | ETL & Automation Specialist

IBM-certified Backend Engineer ( More than 13 certificates ) with extensive experience in developing high-performance APIs and optimizing workflows. I build efficient backend systems, automation solutions, and ETL pipelines that turn messy data into reliable, production‑ready services. With 3+ years delivering Python backends (Django, Flask), I focus on measurable outcomes: faster processing, fewer manual steps, and reproducible deployments. What I deliver: - Production REST APIs and microservices. - Robust ETL pipelines for unstructured documents → ML‑ready datasets. - Containerized deployments (Docker) and CI/CD automation. - Clear documentation, tests, and maintainable code. Proof of impact: - Built an ETL pipeline that processed thousands of non‑standard financial/legal documents into structured data with >95% extraction accuracy, cutting manual review by ~80%. - Delivered secure Python automation for a financial client to process large datasets and automate deployments, improving reliability and reducing manual intervention. How I work: - Problem‑first: I map the workflow, propose 2–3 options with trade‑offs (cost, complexity, maintenance), then implement the simplest solution that meets requirements. - Collaborative: regular updates, short demos, and documented handover so non‑technical stakeholders can use and maintain results. - Quality‑driven: type hints, unit/integration tests, logging/monitoring, and CI pipelines to keep systems reliable.
