Data Scientist | AI & ML Engineer | Data Analyst | Python | SQL | Power BI | LLM & RAG
Hi, I'm Shahab ๐
Most businesses are sitting on data they're not using and drowning in manual work they shouldn't be touching. I build the machine learning models, AI applications and dashboards that fix both and I make sure they actually ship, not just sit in a notebook.
Over the past 5+ years I've helped companies turn messy data and repetitive workflows into predictive models, LLM-powered tools, and BI dashboards their teams actually use to make decisions.
๐ง ๐ช๐ต๐ฎ๐ ๐ ๐ฐ๐ฎ๐ป ๐ต๐ฒ๐น๐ฝ ๐๐ผ๐ ๐ฏ๐๐ถ๐น๐ฑ:
- Data analysis & exploration, turning messy raw data into clear answers and insights
- Statistical analysis & A/B testing, hypothesis testing, significance, and confidence behind your decisions
- Data visualization & Power BI dashboards, reports non-technical stakeholders actually understand
- Predictive & forecasting models, churn, demand, pricing, classification
- AI assistants and chatbots powered by LLMs (OpenAI, Hugging Face)
- RAG systems that let a model answer from YOUR documents and data
- Power BI dashboards that turn raw data into clear, decision-ready reporting
- Python automation that removes hours of manual work every week
- End-to-end data pipelines cleaning, processing, deployment

I am CISSP certified and seasoned information security consultant and CISO enhancing security posture of companies.
As the Chief Information Security Officer (CISO), I am responsible for leading the development and execution of the organizationโs cybersecurity strategy, focusing on protecting critical assets and ensuring compliance with regulatory standards. My role involves helping start-ups and SaaS-based products build secure and compliant systems by providing guidance on Governance, Risk, and Compliance (GRC), ensuring they meet industry best practices and regulatory requirements, such as GDPR, HIPAA, SOC 2, and ISO 27001.
A key aspect of my work is incident response, where I manage the process with the necessary tools and defined roles, ensuring rapid and effective responses to security events. I oversee the administration of SIEM and SOC tools, perform threat management, modelling, and develop use cases for security monitoring. Additionally, I mentor and guide the SOC team, facilitating knowledge transfer and promoting skill development. I ensure the integration of both standard and non-standard logs into SIEM and adapt security monitoring rules to meet business requirements.
I am also responsible for building and maintaining incident response playbooks, creating reports and dashboards, and working closely with stakeholders to improve security operations. I provide oversight on analysis activities and collaborate with technical and business teams to resolve incidents. I continuously evaluate emerging threats and vulnerabilities, keeping our incident response procedures up-to-date and effective.
Along with managing security operations, I focus on securing AI and machine learning technologies, safeguarding against risks such as data poisoning, adversarial attacks, and algorithmic bias. I guide start-ups in implementing responsible AI practices, securing AI pipelines, and adhering to evolving regulations.
In my leadership role, I balance strategic oversight, technical expertise, and practical advice, enabling organizations to scale securely, maintain compliance, and leverage technology to drive growth while upholding a strong security posture.

โ๏ธ Medical & health education writing โ courses, ebooks, curricula, exam prep guides
โ๏ธ Full research lifecycle support โ study design, methodology, implementation, data analysis, manuscript writing, and journal publication (Q1 journals)
โ๏ธ Quantitative data analysis for observational studies and clinical trials โ SPSS, Stata, R
