About Me
I'm Kittipoom Malaikritsanachalee, a Computer Science graduate from Chulalongkorn University. I specialize in full-stack development and backend engineering, with hands-on production experience at IBM and a track record of shipping end-to-end projects with Python, TypeScript, and modern web frameworks.
I believe in writing clean, efficient code that solves real problems — whether that means profiling a slow database query, designing an API from scratch, or wiring up a full deployment pipeline. I always look for the smarter, more robust solution.
I care about code that's maintainable, systems that handle failure gracefully, and teams that ship consistently. Open to full-time backend or full-stack roles where engineering quality actually matters.

Experience
IBM
Application Developer Intern
May 2025 – Aug 2025
- ▸Designed and developed the Service Details API for ConnectX — an enterprise self-service portal enabling clients to manage network ports and VXC connections — taking full ownership from API design through implementation using TypeScript and NestJS.
- ▸Improved query performance by profiling slow endpoints with SQL EXPLAIN, restructuring TypeORM joins, and adding indexes on hot-path columns — resolving data retrieval bottlenecks in the Service Details module.
- ▸Collaborated with product stakeholders to refine API specifications and delivered backend updates consistently across agile sprints with fast turnaround.
- ▸Built a database seed script to load ~1,000 rows from structured .xlsx files into PostgreSQL — initially written in Python, then migrated to JavaScript to align with the NestJS codebase.
