About David E.

I solve impossible production problems in distributed systems using the scientific method.When your team is stuck for weeks on intermittent deadlocks, memory leaks, or performance issues—and standard debugging has failed—that\'s when companies bring me in.MY APPROACHI apply systematic falsification to root cause analysis:• Generate testable hypotheses from symptoms• Work to DISPROVE each hypothesis through rigorous testing• Document eliminated causes to narrow problem space• Build custom diagnostic tools when standard approaches fail25+ years debugging distributed systems with formal training in reinforcement learning under Andrew Barto (UMass Amherst).REPRESENTATIVE WINS• 82% → 99.9%+ availability on satellite IoT platform• 10x throughput on 3M IOPS Key/Value storage via novel caching• Found \"deadlock\" was actually packet forwarding loop—systematic falsification revealed non-obvious root cause• Built custom memory leak detector that found issues Valgrind/AddressSanitizer missed• Created O(n) algorithm for factoring bit semiprimesNOT JUST A DEBUGGER—AN INVENTOR• 20+ patents in distributed systems, caching, storage• Best Paper Award 2017)• Multiple peer-reviewed publications• Novel algorithm development for hard problemsCREDENTIALSMBA Northeastern | BS CS UMass Amherst | 25+ years at EMC, 3PAR/HPE, Samsung, Globalstar | 500% productivity increase in IP generation | 75% bug reduction through methodology trainingENGAGEMENT MODELSEmergency Diagnostic (48-72 hrs)| Deep Investigation (1-2 weeks)| Fractional Retainer | Team TrainingIf your team is stuck on a problem costing revenue or availability, let\'s talk. d••••••@gmail.com | 50••••••08 | linkedin.com/in/devans
