I design and build production-oriented applications across Web, Mobile, Desktop, AI, and Cloud-Native Infrastructure.
I have end-to-end engineering capabilities spanning product prototyping, frontend and backend development, data modeling, AI integration, containerized delivery, Kubernetes orchestration, and production observability.
My current focus includes:
- 🤖 AI Agents, RAG, tool calling, and multi-agent collaboration
- 🌐 Full-stack Web, Mobile, and Desktop application architecture
- ⚡ High-performance APIs, asynchronous tasks, and event-driven systems
- ☸️ Docker and Kubernetes-based cloud-native platforms
- 🔍 Production observability through metrics, logs, and monitoring
- 🎬 AI-powered audio, video, OCR, and computer vision workflows
- LLM application and AI Agent architecture
- Retrieval-Augmented Generation and knowledge base systems
- Tool calling, workflow orchestration, and multi-agent collaboration
- Speech recognition, speech synthesis, and audio processing
- OCR, computer vision, and generative media pipelines
- AI model serving, API integration, and containerized deployment
- React, Next.js, and TypeScript frontend architecture
- Backend services built with FastAPI, Django, Gin, and Spring Boot
- RESTful APIs, authentication, authorization, and state management
- Cross-platform Mobile and Desktop application development
- Relational, document, cache, and search-oriented data architecture
- Docker image building and multi-environment delivery
- Kubernetes workload deployment and orchestration
- Deployment, Service, and Ingress configuration
- ConfigMap, Secret, and environment configuration management
- Health checks, resource limits, and horizontal autoscaling
- Rolling updates, fault recovery, and high-availability practices
- Reverse proxy and TLS termination with Nginx and Caddy
- Observability with Prometheus, Grafana, and the ELK Stack
- Event-driven architecture with Kafka
- Asynchronous task processing with Celery
- Redis caching, distributed state, and performance optimization
- Service discovery and coordination with Consul and etcd
- Search and log analytics with Elasticsearch
- Metrics collection and visualization with Prometheus and Grafana
