🧑‍💻 About Me

  • 🏢 Currently working as a Python Full Stack Developer at Assurify Technology Pvt Ltd., building enterprise after-sales service & warranty management platforms.
  • 🐍 I build scalable REST APIs and backend systems using Python, Django, and Django REST Framework, backed by MySQL / PostgreSQL.
  • 🤖 I actively design and build AI Agents, RAG chatbots, LLM orchestration pipelines, and multimodal AI solutions using Azure OpenAI (GPT-4o Vision), Google ADK, and Vertex AI (Gemini).
  • ☁️ Comfortable across the cloud-native stack — Microsoft Azure, Docker, Kubernetes (AKS), Azure DevOps CI/CD, with Redis & Celery for caching and async workflows.
  • ⚡ I focus on writing optimized, maintainable code, improving performance through efficient database design, caching strategies, and asynchronous task processing.
  • 📊 Production experience with observability & monitoring — Sentry, Prometheus, Grafana, Azure Log Analytics.
  • 🌱 Completed the #100DaysOfCode challenge and solved 200+ DSA problems on LeetCode — strong coding discipline and daily development habits.
  • 🎓 Certified in LLM Course (Hugging Face), Agents Course (Hugging Face), and 5-Day AI Agents Intensive Vibe Coding (Google, Badge Earned).
  • 📫 Reach me at alwinxaviera19@gmail.com

🤖 AI & GenAI Focus

I've built AI-powered systems in production, including:

  • An AI Damage Estimation Agent (Google ADK + Vertex AI Gemini for orchestration, Azure OpenAI GPT-4o Vision for image/document understanding) — automating spare-part prediction, repair summaries, and confidence scoring.
  • RAG chatbots and document intelligence pipelines combining OCR, multimodal vision models, and LLM-based reasoning for enterprise workflow automation.
