I build data platforms and BI systems that turn messy data into reliable dashboards and automated analytics.
I work daily in production BI environments, specializing in Apache Superset, secure multi-tenant dashboards, and backend data systems. My focus is building analytics platforms that are stable, scalable, and easy for teams to use.
What I Do Best
— Customize and extend Apache Superset (RLS, Jinja templating, global parameters, alerts)
— Develop custom chart plugins and extend the platform with new visualization capabilities
— Design and optimize complex SQL queries (PostgreSQL, MSSQL, Firebird)
— Build backend logic in Python for data workflows and automation
— Deploy systems using Docker and containerized environments
— Set up CI/CD pipelines (GitHub Actions, GitLab CI)
— Build internal dashboards and data tools for business teams
Real-World Experience
— Implemented global parameter systems inside BI environments
— Built SQL Lab extensions to execute stored procedures and generate datasets
— Worked with multi-database synchronization and metadata systems
— Managed production deployments and infrastructure debugging
— Automated workflows using Python and Bash
If you need someone who understands both backend engineering and the data layer, I can help design and implement a clean, reliable solution from the start.
I focus on clean architecture, long-term maintainability, and real business impact.

If your Cloud bill keeps climbing and your release velocity doesn't, that's usually an infrastructure problem, not a team problem.
I’m a Senior Cloud Platform Architect and DevOps Engineer with 10+ years building and running production infrastructure across AWS, Azure, GCP, Oracle Cloud, and OpenStack, including Huawei Cloud, T Cloud Public and Red Hat OpenStack/OpenShift.
A few concrete examples from my work:
• Led core platform operations for T Cloud Public (formerly OTC) across multiple EU regions, improving availability, elasticity, and automation for large multi‑tenant environments
• Built and operated DevOps and SRE platforms for AI products on AWS and Azure (EKS, ECS, ECR, RDS, S3, DynamoDB), including CI/CD, observability, and incident response
• Delivered carrier-grade telco/NFV‑oriented Cloud solutions on OpenStack and OpenShift under strict reliability and performance requirements
• Cut cross-cloud infrastructure costs by 35%, reduced deployment times from weeks to hours through end-to-end automation, and lowered production incident recovery (MTTR) by 60%
With Top Rated Plus status and a 100% Job Success score, I've completed numerous projects, including Cloud Migrations, AI deployments, Integrated systems, Automation strategies, and Infrastructure optimization initiatives for enterprise clients. For Data-heavy projects, I build pipelines with Databricks and Azure Data Factory to handle ETL, orchestration, and service integration.
AI and automation are becoming an increasingly important part of the work I do with clients. I help teams move beyond “AI in a notebook” by wiring the AI models and agents into real, production-grade infrastructure with proper CI/CD, testing, monitoring, and deployment flows, so AI workloads are treated like first-class production services, not just prototypes or POCs experiments.
What I actually do for clients:
• Design and migrate multi-cloud or hybrid infrastructure (AWS, Azure, GCP, OCI, OpenStack)
• Build CI/CD pipelines and infrastructure-as-code with Terraform, Ansible, GitHub Actions, GitLab, and Jenkins
• Stand up and run production Kubernetes, i.e. Helm, ArgoCD, and Istio, on cloud or bare metal
• Build data pipelines with Databricks, Azure Data Factory, and Kafka for ETL and service integration
• Move AI/ML workloads out of notebooks and into real production systems, with proper CI/CD, monitoring, and deployment, not a script everyone's afraid to touch
I'm AWS, Azure, and Oracle Cloud certified, and I'm just as comfortable lower in the stack, KVM, QEMU, Ceph, SR-IOV, NFV, Proxmox, VMware, which matters if your setup includes private cloud or anything telco-adjacent.
I work directly with founders and engineering leads. I'll tell you straight if something's a quick fix or a real project before I quote it, and I document what I build so your team isn't stuck depending on me to keep the lights on.
If your infrastructure's a mess, your pipelines keep breaking, or your cloud spend doesn't make sense anymore, message me with what you're working with. I'll give you a real read on what's wrong and what it'd take to fix it.

I build and scale production-grade 𝗔𝗜, 𝗦𝗮𝗮𝗦, 𝗮𝗻𝗱 𝗳𝗶𝗻𝘁𝗲𝗰𝗵 𝘀𝘆𝘀𝘁𝗲𝗺𝘀 that handle real users, real data, and real business constraints, not prototypes or proof-of-concepts.
With 𝟭𝟯+ 𝘆𝗲𝗮𝗿𝘀 𝗼𝗳 𝗳𝘂𝗹𝗹-𝘀𝘁𝗮𝗰𝗸 𝗲𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲, I work across backend architecture, frontend systems, cloud infrastructure, and AI integration to deliver platforms that are built for reliability, scalability, and long-term maintainability.
𝗖𝗹𝗶𝗲𝗻𝘁𝘀 𝘁𝘆𝗽𝗶𝗰𝗮𝗹𝗹𝘆 𝗵𝗶𝗿𝗲 𝗺𝗲 𝘄𝗵𝗲𝗻:
• They are building a SaaS or AI product that needs to scale beyond MVP
• Their backend or architecture is becoming unstable under real usage
• They need secure, production-ready fintech or payment systems
• They are integrating AI into real workflows (not just chat demos)
• They need senior-level ownership across full product delivery
𝗪𝗵𝗮𝘁 𝗜 𝗯𝘂𝗶𝗹𝗱:
• AI-powered systems that automate real business workflows
• Multi-tenant SaaS platforms with billing, roles, and scalable architecture
• Fintech backends with secure payments, audit trails, and reliability-first design
• Marketplaces and LMS platforms designed for high user concurrency

𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸:
I operate 𝗹𝗶𝗸𝗲 𝗮 𝗽𝗿𝗼𝗱𝘂𝗰𝘁-𝗳𝗼𝗰𝘂𝘀𝗲𝗱 𝗲𝗻𝗴𝗶𝗻𝗲𝗲𝗿, not just a task executor.
That means:
• I design systems with scalability and failure modes in mind
• I flag architectural risks early, before they become expensive problems
• I prioritize clean structure, maintainability, and production stability
• I take ownership from architecture → build → deployment

𝗗𝗲𝗹𝗶𝘃𝗲𝗿𝘆 𝗺𝗶𝗻𝗱𝘀𝗲𝘁:
You won’t need to chase updates or manage micro-details.
I communicate clearly, surface risks early, and ensure systems are built to production standards, not just “working code.”
If you're building a serious product and need someone who can own architecture + execution end-to-end, I’m available for short-term builds or long-term engineering support.
