//Specialized Backend & Systems Architect

The Backbone of Scalable Applications & Resilient Systems.

I architect high-throughput backend APIs, optimize sluggish SQL databases, and build reliable server infrastructure. Helping SaaS platforms and E-commerce stores stay fast, secure, and unbreakable under peak load.

// 01·SYSTEM BOTTLENECK DIAGNOSTICS

Engineered Solutions for Critical System Bottlenecks

Where applications break under pressure, and how I fix them.

[01]DIAGNOSTIC_MODULE

Database Latency & Deadlocks

Symptom: High CPU, unindexed table scans, connection pool exhaustion under flash sales.

Fixing unindexed SQL queries, locking bottlenecks, query execution plan tuning, and implementing connection pooling with read replicas.

RESULT METRICP99: 1400ms → 28ms · DEADLOCKS: 0
[02]DIAGNOSTIC_MODULE

Crash Resistance Under Peak Load

Symptom: API gateways timing out, memory leaks, and cascading server crashes.

Building resilient background queues, asynchronous task workers, backpressure management, and memory-safe Node.js cluster processes.

RESULT METRICBACKPRESSURE: BUFFERED · UPTIME: 99.99%
[03]DIAGNOSTIC_MODULE

Messy Code & Fragile APIs

Symptom: Uncaught runtime errors, lack of schema validation, untyped breaking payloads.

Restructuring legacy monolithic code into clean, strictly-typed TypeScript architectures with automated error tracking and robust contract tests.

RESULT METRICTYPE SAFETY: 100% · UNCAUGHT ERR: 0
[04]DIAGNOSTIC_MODULE

Infrastructure & Data Loss Blindspots

Symptom: Single points of failure, missing snapshot verification, raw exposed ports.

Implementing isolated Docker environments, reverse proxy configs with TLS termination, and rigorous automated 3-2-1 backup schemes.
