I work with organizations to secure and manage production cloud environments across Microsoft Azure and AWS. My focus is on building structured, secure, and well-governed platforms that are ready for real-world operations and compliance requirements. In Azure, I handle everything from tenant configuration and subscription structure to identity security and network design. I implement RBAC with proper least-privilege access, configure Entra ID (Azure AD), MFA, Conditional Access, and Privileged Identity Management. I deploy and tune Microsoft Sentinel, configure Defender for Cloud, enforce governance through Azure Policy, and set up monitoring with Azure Monitor and Log Analytics. I design secure VNet architectures with subnet segmentation, NSGs, Azure Firewall, DDoS protection, Key Vault integration, and disk encryption. Backup strategies, disaster recovery planning, and infrastructure automation using ARM, Bicep, and Terraform are also part of my day-to-day work. On AWS, I design secure VPC environments with proper subnet routing, NAT gateways, internet gateways, and security groups. I implement IAM users, roles, policies, and cross-account access following least-privilege principles. I configure CloudTrail, GuardDuty, CloudWatch logging, and centralized monitoring. My experience includes EC2, RDS, load balancers, SSL configuration, Auto Scaling, S3, Lambda, ECS, and infrastructure automation using Terraform and CloudFormation. I also have hands-on experience working with SIEM platforms including Microsoft Sentinel, IBM QRadar, ArcSight, Elastic, and Wazuh, along with Microsoft XDR technologies for monitoring and investigating advanced threats. My approach is straightforward and security-focused: strong identity controls, proper network segmentation, continuous monitoring, and infrastructure built to be maintainable over time. If you need someone who understands both Azure and AWS in practical production scenarios, I can help you design, secure, and optimize your cloud environment properly.

I am a professional Golang backend engineer with over 5+ years of professional experience building backends for various projects. - I'm comfortable with any Go HTTP library, but my favorite is Chi. - If data retrieval becomes too complex, I use GraphQL for better performance and ease of use. - I love using gRPC for internal service connections. - For real-time data communication between the frontend and backend, I use zishang/socket.io or gorilla/websocket(sometimes FE dev prefer socket.io because it is easier to implement). - Typically, I use Kafka for message queuing, but for smaller use cases, I prefer Redis queue. - PostgreSQL is my top choice for a database. - I can work with Kubernetes as a developer, though not as a DevOps specialist. - The ELK stack is my preferred tool for analyzing log data. - I am also capable of setting up CI/CD pipelines using GitHub and GitLab. - Lastly i can help frontend dev to help integrate backend api.

Greetings. I am an experienced Node.JS backend developer. I have almost 3 years of commercial experience. I have worked with different databases, I am an expert in both SQL and NoSQL. At the same time, I am familiar with both OLTP and OLAP databases and their differences, I have read "The Data Warehouse Toolkit" written by Kimball and constructed an OLAP database in Redshift. I am an expert in PostgreSQL functions ( recursive as well ) and triggers, good knowledge of channels and listeners for DB changes. In one of my projects, I synced PostgreSQL with Redis and ElasticSearch by opening a channel in PostgreSQL and pushing notifications to it while Node.JS was listening to them and updating ElasticSearch and Redis in realtime ( there was a debouncer to prevent some unexpected multiple updates ). Redis was used to handle permissions and only the server was accessing it and ElasticSearch was used for searching our catalogue. I have used Socket.io to make a chat for one of my e-commerce projects to handle a conversation between the user and admin. I have experience with AWS S3, SES, RDS, Glue, and Redshift. For most of the backend projects I used Express, however, I can also use Fastify. I have experience with React, and I have built several admin panels.

* 9+ years of programming and enterprise-level application development experience including software development strategy planning, requirement analysis and prototyping, design, development, testing, debugging, performance tuning and production support. * Experience in handling search using Apache Solr, Java, and caching tools * Experience in developing ecommerce features like Autosuggestion, Text tagger, Spellcheck, Elevate, Indexing, Schema. * Developed multiclass classification model for search using Deep learning Transformer with Bert and Redis AI server for model deployment * Worked on multiple programming languages Java, Python, Php

I help teams build data platforms that hold up in production: pipelines, warehouses, real-time analytics, and practical AI layers when they actually solve a business problem. I am currently a Data Engineer at Microsoft. Over the last 13+ years I have worked across enterprise, sports, ride-hailing, telecom, and consulting environments, including beIN Sports, EY, Yassir, Flytxt, and Microsoft partner projects in Qatar, the UAE, and India. The work I am usually brought in for: - Building or fixing Azure, Microsoft Fabric, and Databricks data platforms - Designing ETL/ELT pipelines that are reliable and easy to operate - Moving teams from fragile scripts or legacy reporting into cleaner cloud architecture - Setting up warehouses, lakehouses, dbt models, orchestration, and monitoring - Adding simple, useful AI/chat interfaces on top of structured business data A few examples: - Built analytics infrastructure for FIFA World Cup 2022 workloads at beIN Sports using GCP, BigQuery, PySpark, and dbt. - Worked on live analytics pipelines for Yassir's ride-hailing operations, where late or inaccurate trip data quickly becomes a real business problem. - Led Microsoft ecosystem modernization work with Fabric, Synapse, Azure Data Factory, ADLS, and Databricks. - Built ingestion frameworks and DevOps practices for financial and audit datasets at EY. - Designed PySpark and big data systems for telecom customer analytics at Flytxt. My usual stack: Microsoft Fabric, Azure Synapse, ADF, ADLS, Databricks, GCP, BigQuery, PySpark, SQL, dbt, Airflow, Cloud Composer, Kafka, Elasticsearch, and Power BI. I am hands-on and fairly direct. I like understanding the messy reality first, then building something the team can actually run after the project is done. No over-engineering for the sake of it; just clean data flow, clear ownership, and systems that do not need constant babysitting. If you are dealing with a slow pipeline, a warehouse rebuild, a cloud migration, or a data product that needs a practical AI layer, I am happy to have a straightforward conversation and see if I can help.
