About Me

Problem-Solving Approach

Real-world decisions and trade-offs from actual projects

Technical Decisions
  • • Chose MySQL over MongoDB for better team familiarity
  • • Prioritized query optimization over caching for sustainable performance
  • • Selected simple rsync backup over complex solutions for reliability
  • • Used Laravel over microservices to match team expertise
Debugging Approach
  • • Start with logs and error messages, not assumptions
  • • Reproduce issues in development before touching production
  • • Document solutions for team knowledge sharing
  • • Ask for help when stuck (learned this the hard way)
