Cloud Security & DevSecOps Engineer for teams running on AWS, Azure, GCP, BigQuery, ETL, and CI/CD.
I help teams secure cloud infrastructure, data pipelines, and deployment workflows without slowing engineering down. That includes IAM, Entra ID, vulnerability assessment, security analysis, CI/CD hardening, DevSecOps, and information security work across the full environment.
Most clients come to me when things already feel messy. Access is too open, cloud infrastructure has grown without clear security rules, CI/CD is moving fast without enough guardrails, and nobody is fully sure where the real risk is.
That is exactly why they hire me.
I do not just point out issues. I work on the actual infrastructure, access model, cloud setup, and delivery flow so your team can reduce risk, stay organized, and keep shipping with more confidence.
𝙎𝙚𝙧𝙫𝙞𝙘𝙚𝙨 𝙄 𝙊𝙛𝙛𝙚𝙧:
𝟭. Cloud Security Reviews: I review cloud infrastructure, identity, networking, permissions, workloads, and data flows to find real security gaps and give clear priorities.
𝟮. DevSecOps & CI/CD Security: I secure CI/CD workflows so teams can build, test, and deploy with better controls, fewer mistakes, and less production risk.
𝟯. IAM & Entra ID Hardening: I improve IAM, Entra ID, roles, permissions, least privilege, and access design so the right people get the right access without unnecessary exposure.
𝟰. Vulnerability Assessment: I run vulnerability assessment work, validate findings, remove noise, and help your team focus on what actually matters.
𝟱. Security Analysis: I break down risks in plain English so leadership, engineering, and operations can understand what is wrong, what matters most, and what to fix first.
𝟲. Cloud Infrastructure Security: I help secure infrastructure in AWS, Azure, and GCP, including compute, networking, storage, identity, and deployment patterns.
𝟳. Data Engineering & ETL Security: I support secure ETL flows, BigQuery environments, and data architecture decisions where access, movement, storage, and control of data matter.
𝟴. Information Security Support: I help teams improve their information security setup with practical controls, documentation, clearer ownership, and cleaner processes.
𝟵. Quality Assurance for Security Changes: After fixes are made, I verify that the changes actually work and that the environment is more secure, stable, and easier to manage.
𝙏𝙝𝙚 𝙠𝙞𝙣𝙙 𝙤𝙛 𝙬𝙤𝙧𝙠 𝙄 𝙝𝙚𝙡𝙥 𝙢𝙤𝙨𝙩 𝙬𝙞𝙩𝙝:
🔹 Securing AWS, Azure, and GCP environments without slowing down delivery
🔹 Hardening IAM, Entra ID, permissions, and access controls
🔹 Improving CI/CD security and building cleaner DevSecOps workflows
🔹 Running vulnerability assessment and turning findings into real fixes
🔹 Securing ETL pipelines, BigQuery environments, and data infrastructure
🔹 Helping engineering teams understand and reduce cloud security risk

Most dashboard problems are not dashboard problems. A number that does not match what someone counted by hand usually broke three steps earlier, somewhere in ingestion or a transformation nobody tested. That is where I actually spend my time as a Data and AI Engineer, and the chart at the end is the easy part.
My pipelines typically run on Airflow or Mage AI. Anything that needs to move in real time goes through Kafka and PyFlink. On AWS I work with Lambda, S3, EventBridge, and SNS, and bad records get pulled into a quarantine bucket instead of quietly sitting in a table someone trusts. For transformation, I build dbt models on Snowflake and PostgreSQL, structured bronze through gold, with schema tests and business rule checks written into the models themselves so a broken assumption gets caught in the pipeline, not by whoever opens the report next.
Reporting comes after the data is solid. I build in Power BI or Tableau around the one question the business actually needs answered, not a stack of generic rollups nobody reads. When the need is document search or research rather than dashboards, I build RAG systems that score their own retrieval accuracy, so a weak answer gets flagged instead of handed over as confident nonsense.
A few things I have shipped recently: a district-level KPI dashboard on Snowflake and Power BI built from layered dbt models, incremental dbt pipelines feeding logistics and lending risk reporting, a real-time Kafka and PyFlink pipeline with event-time processing sinking to PostgreSQL, and a serverless AWS pipeline where a quarantine bucket keeps bad files from ever touching the tables people query.
If a tool is not something I have genuinely used, I will say so instead of guessing my way through your job. Tell me what the reporting needs to answer and where your data lives right now, whether that is Excel, PDFs, or a handful of systems that do not talk to each other. I will give you a straight read on whether it is a small fix or a bigger rebuild.

I build AI products that make it to production: RAG document intelligence, video AI pipelines on self-hosted LLMs, and AI-first SaaS platforms.
$200K+ earned, 6,200+ hours, 100% Job Success, Top Rated Plus.
WHY FOUNDERS AND TEAMS BRING ME IN:
✅ SaaS platforms, B2B marketplaces, and AI systems shipped since 2020; from idea to production, several still live and earning
✅ Builder of Quanta, and the AI document platform behind 1,000+ SBA loans and $500M+ in funded transactions
✅ Hands-on senior engineer: you work directly with me on architecture and code, on every engagement. When a project needs more hands, I scale with my own vetted team (Arithmiks, 10 engineers) instead of handing you off
✅ Top Rated Plus (top 3% on Upwork). Clear trade-offs, honest assessments, no fluff
WHAT I BUILD:
📄 1. AI Document Intelligence and RAG Systems Contract review with clause-level risk flags and exact-section citations. Hybrid retrieval (dense + sparse vectors, Qdrant), structured LLM extraction validated against schemas, audit-logged answers that never cite what wasn't retrieved. Shipped inside a lending platform that has supported 1,000+ SBA loans and $30M+ in funded transactions: AI document naming and summarization, package-level analysis, and credit memorandum generation.
🎥 2. Video and Media AI Pipelines Fully automated pipelines: speech-to-text (Whisper) with speaker diarization, word-level timestamps and subtitles, frame analysis, face detection, chapter segmentation, tag scoring, and natural-language chat over indexed video libraries. Multilingual (including Arabic and English). Deep experience with self-hosted LLM inference (vLLM) on GPU Kubernetes clusters with workflow orchestration, for teams with data-residency or firewall requirements.
💬 3. AI Chatbots and Assistants (with citations, not hallucinations)
Chat interfaces over documents, data, and video metadata — every factual answer carries a clickable citation to the source; the system says "not found" instead of guessing. RBAC-scoped retrieval, per-org data isolation, full RAG audit logs.
🚀 4. B2B Marketplaces and FinTech Workflows
Vendor portals, quote and order workflows, Stripe payments at real transaction volume, e-signature flows, multi-role approval pipelines, compliance-aware payment architecture.
🏦 5. Cloud, DevOps and Self-Hosted AI Infrastructure
AWS (EC2, S3, Lambda, RDS, API Gateway), Docker, CI/CD — and the part most teams can't offer: self-hosted LLM deployments (vLLM, Kubernetes, GPU scheduling) for clients with data-residency or firewall requirements.
☁️ 6. Cloud, DevOps and Self-Hosted AI Infrastructure
