Khoa L.

I’m a Data Engineer and Backend Developer with over 4 years of experience building data-driven systems, scalable ETL pipelines, and backend services using Python, Apache Spark, Django, and AWS. I specialize in turning complex data into reliable, high-performance systems - from big data pipelines in aviation to AI-powered web applications and data enrichment tools for clients across Europe and Asia. My recent work includes: 🚀 Optimizing enterprise ETL pipelines (SSIS, Spark) - improving runtime by up to 50% and ensuring data consistency across production environments. 🧠 Building AI-based tools - developing Django apps that use LLMs for summarization, content generation, and intelligent data processing. ☁️ Deploying scalable cloud solutions - containerized and orchestrated microservices using AWS ECS, ECR, and serverless tools. 🔍 Designing efficient data flow architectures - integrating NoSQL databases like ElasticSearch for real-time data retrieval from large scraping pipelines. I bring a mix of software engineering discipline and data pipeline expertise, backed by an Engineer’s degree in Information Technology and a Master’s in Computer Science. My approach combines technical depth, reliability, and clear communication. Ensuring every project I take on is delivered clean, scalable, and production-ready.
