What I'm looking for

I'm focused on SRE, cloud infrastructure, and applying these principles to AI/ML workloads.

At Blue Collar Technologies LTD., I build and maintain production applications across CRM, Field Management, and HRMS. I’ve optimized backend APIs and PostgreSQL queries with Redis caching, improving API response times by up to 40%.

I also containerize applications with Docker and manage cloud deployments across AWS EC2, ALB, and S3. I automated CI/CD workflows with GitHub Actions and work across application and infrastructure layers to troubleshoot production issues.

At Lawris AI, I built backend services for an AI-powered legal technology platform using Django. I integrated OpenAI APIs for legal document analysis and extraction, and built REST APIs and asynchronous processing pipelines with Celery and Redis.

At HNG Tech, I developed RESTful APIs using FastAPI and Go, integrated OpenAI’s API, and implemented asynchronous task processing with Celery. I also automated API tests with Postman and Newman and developed end-to-end tests with Selenium.
