About me

I am a multi-domain engineer with expertise in cloud infrastructure, networking, and embedded IoT systems. My background includes hands-on work with AWS and Azure environments, secure network design (VPC, VPNs, IAM, VLANs), and automation using Terraform, GitHub Actions, and shell scripting. I hold certifications including AWS Solutions Architect Associate, AWS Machine Learning, Azure Administrator (AZ-800), and Cisco CCNA.
In parallel, I have worked on embedded, IoT, and AI document search projects, including sensor-based systems, edge AI deployment, cloud-to-device communication, and internal AI-based document search to improve business operations.
๐Ÿ”ท Core Technical Expertise

  • Cloud Infrastructure: VPC, VPNs, IAM, EC2, RDS, S3, CloudTrail, AD

  • Networking: VLANs, Cisco Routers/Switches, Site-to-Site VPN, DHCP

  • DevOps & Automation: Terraform, GitHub Actions, Bash, Linux

  • IoT/Embedded Systems: ESP32, Arduino, Raspberry Pi, Sensors, MQTT

  • RAG Systems: Bedrock, LangChain, FAISS

  • AI/ML: Streamlit, OpenAI, Hugging Face Transformers

  • PCB & Firmware: Embedded C/C++, Protel, ADC/PWM, GPIO

Recent Projects
1. FortiGate Firewall Migration and Network Segmentation
Worked on FortiGate firewall upgrade from an older device to a newer model, including firmware verification, interface configuration, routing review, NAT/firewall policy checks, VPN-related routing, and connectivity troubleshooting. Supported VLAN-segmented network design and validation for secure communication between internal systems.
2. Graylog-Based Log Monitoring and Troubleshooting
Set up and worked with Graylog for centralized log monitoring and troubleshooting. Configured log collection and reviewed system/network logs to support issue investigation, visibility improvement, and operational monitoring across infrastructure components.
3. On-Premise RAG-Based AI Document Search System
Designed and built an on-premise RAG-based AI document search and compliance assistant using FastAPI, PostgreSQL, Redis, Celery, Qdrant, BGE-M3 embeddings, and local LLM inference with llama-server. Implemented document upload, job tracking, OCR/text extraction, cleaning, chunking, vector indexing, and semantic document search in a multi-VM private network environment.
