Bug Fixing

Stuck on a regression or a flaky production failure? We trace the root cause, document the findings, and ship a verified fix with regression coverage to reduce the risk of recurrence.

Memory Leak Tracing

Memory leak investigation across Node, browsers, and native runtimes. We use heap snapshots, retainer analysis, allocation profiling, and fix verification to identify persistent memory growth and restore stable performance.

03 / 09

Performance Regressions

Identify and resolve performance regressions using commit bisection, profiling, flame graphs, and continuous benchmarks, with measurable improvements verified before release.

04 / 09

Cross-Browser Issues

Cross-browser compatibility fixes across Safari, Firefox, and mobile WebViews. We isolate browser-specific failures with minimal reproductions, implement robust fixes, and verify behavior across affected environments before release.

05 / 09

Crash Reporting Setup

Crash reporting and monitoring setup with Sentry, Crashlytics, or Bugsnag. We configure source maps, deobfuscation, release tracking, and actionable alerts so production crashes are easier to diagnose and resolve quickly.

06 / 09

Security Vulnerability Patching

Security vulnerability remediation covering CVE response, dependency upgrades, and OWASP Top 10 mitigations. We reproduce and validate vulnerabilities with controlled exploit tests, then verify that fixes address the underlying risk without introducing regressions.

07 / 09

Legacy Code Triage

Triage and audit inherited codebases to identify risky dependencies, dead code, technical debt, and high-impact refactoring opportunities. We prioritize findings by risk and business impact, focusing first on changes that improve stability and maintainability.

08 / 09

Race Condition Diagnosis

Diagnose and resolve race conditions and concurrency bugs by reproducing failures under controlled conditions. We use appropriate synchronization strategies including locks, queues, and idempotent retry logic to restore reliable system behavior and prevent recurrence.

09 / 09

Database Query Tuning

Diagnose and optimize slow database queries across PostgreSQL, MySQL, and MongoDB. We analyze query plans, identify missing indexes and N+1 patterns, and tune connection pools to improve response times and database efficiency.
