Emergency Code Debugging & System Repair for Pakistani Applications
Production outages, memory leaks, and broken database transactions cost your business revenue every minute. Senior full-stack engineer Mr Umer Malik provides rapid, surgical debugging and system remediation for mission-critical web applications across the Pakistan.
Core Capabilities & Production Deliverables
Direct architectural execution by senior engineer Mr Umer Malik with zero agency dilution.
Root-Cause Triage & Remediation
Surgical diagnosis of silent errors, fatal exceptions, race conditions, and unhandled promise rejections in production code.
Database Lock & Slow Query Resolution
Investigating deadlocks, unindexed queries, connection pool exhaustion, and long-running transactions in PostgreSQL and MySQL.
Memory Leak & CPU Spike Diagnostics
Profiling Node.js, Go, and PHP processes using heap dumps and flamegraphs to eliminate runaway memory leaks and high server CPU usage.
Security Vulnerability Hotfixes
Immediate patching of zero-day exploits, SQL injection vectors, broken access controls, and compromised authentication tokens.
Broken Payment & Webhook Triage
Diagnosing dropped Stripe webhook events, duplicate transaction charges, and silent checkout calculation failures.
Regression Prevention & Unit Tests
Writing automated regression tests for every resolved bug to guarantee the issue never reappears in future software releases.
Why Pakistani Scale-Ups Choose Direct Senior Engineering
Local software houses deliver fragile code and cycle junior interns through your project. Here is the direct senior engineering alternative.
PKT (UTC+5) Instant Daytime Collaboration
Direct, real-time collaboration with senior software architect Mr Umer Malik during standard business hours via Slack, WhatsApp, or phone.
Predictable Milestone Pricing in PKR & Legal NDA
Deliverables quoted in transparent Pakistani Rupees (PKR) with zero open-ended billing, backed by SECP-compliant bilateral mutual NDA and 100% IP assignment.
Sub-30ms Local Edge Caching & Optimization
Systems optimized specifically for Pakistani broadband and mobile data networks (PTCL, Nayatel, StormFiber, Jazz 4G), eliminating lag.
Direct Senior Principal Partnership
Work directly with the lead engineer writing your production architecture with zero account managers or communication lag.
Phased Delivery Roadmap & How This Project Runs
Structured from initial discovery call to production deployment and 100% intellectual property transfer.
Phase 01: Architecture Scoping & Fixed PKR Milestone Scoping
30-minute scoping call to map technical requirements, database architecture, and agree on fixed milestone pricing in PKR with zero hidden fees.
Phase 02: Private Git Repository & Staging Environment
GitHub repository initialized under your organization, signed bilateral mutual NDA under Pakistani Law, and private staging environment deployed.
Phase 03: Fast Iteration Sprints & Weekly Staging Demos
