Profile

A backend engineer focused on outcomes, not just code.

I am a Senior Backend and DevOps Engineer with 12+ years of experience building scalable web platforms, cloud infrastructure, and business-critical systems for millions of users.

My strongest work sits at the intersection of Laravel backend engineering, system architecture, and production operations. I design APIs, payment flows, queue-based processing, real-time features, and database structures that remain maintainable as traffic and team size grow.

I have delivered systems across HRM, payroll, inventory, e-commerce, payment gateways, government service automation, school management, IoT, ERP, SMS/notification delivery, and online ticketing. I apply SOLID principles, repository patterns, automated testing, caching, observability, and CI/CD so teams can ship safely without creating operational debt.

I also lead delivery using Scrum and Kanban, translating business constraints into practical engineering plans and mentoring developers toward cleaner architecture, stronger ownership, and predictable releases.

Backend ArchitectureCloud DeliveryTechnical Leadership
Operating style

Engineering decisions tied to release quality, system health, and team speed.

Production calm

Readable services, rollback paths, queue safety, and observability before scale becomes painful.

Delivery rhythm

CI/CD, ownership, and release routines that help teams ship without recurring operational debt.

Architecture leverage

API boundaries, caching, database strategy, and mentoring that keep systems maintainable.

Impact

Evidence from production systems, not only tool lists.

The work is strongest when backend design, infrastructure, delivery discipline, and team execution are treated as one system. I use that lens to improve performance, reliability, cost, and release speed without creating hidden maintenance debt.

What gets measured

Production signals I validate before recommending architecture changes.

Latency path

API timing, slow queries, cache hit rate, and queue wait time.

Release safety

Rollback plan, migration risk, environment drift, and deployment ownership.

Failure control

Retries, locks, rate limits, abuse protection, alerts, and incident visibility.

15s -> 750msPeak API latency reduction

Caching, query tuning, Kafka flows, and Kubernetes scaling for traffic spikes.

90GB+Database migration handled

MSSQL to MySQL redesign with chunked migration, schema cleanup, and zero data loss.

2.5M+Training records supported

Digital enrollment, biometric attendance, grading, and QR certification workflows.

60%Operational cost reduction

Database and infrastructure decisions that lowered licensing and runtime overhead.

Diagnose

Find the real bottleneck across code, database, queues, infra, deployment, and team workflow.

Stabilize

Control failure modes with caching, rate limits, retries, locks, rollback paths, and monitoring.

Scale

Move high-load paths toward horizontal capacity, event pipelines, optimized storage, and safer releases.

Transfer

Leave teams with documentation, sprint routines, ownership boundaries, and maintainable architecture.

Architecture Review Lens

Where I look first when a platform feels slow, fragile, or expensive.

  • API throughput and latency
  • Database indexes, locks, and reporting queries
  • Queue depth, retries, and dead-letter behavior
  • Deployment risk, rollback, and environment drift
  • Security, abuse protection, and request integrity

The goal is not a long report. The goal is a practical sequence of fixes that improves uptime, speed, release confidence, and team ownership.

Case Studies

Critical problems I have solved in production.

Each case is framed around the failure mode, the engineering intervention, and the operational result. That is how I evaluate whether architecture work is actually useful.

Problem

A high-traffic platform was hitting 12-15 second response times during peak load, with API timeouts, degraded real-time features, and limited concurrency.

Solution

Moved critical services toward containerized deployment, Redis caching, Kafka event processing, query/index optimization, and load-balanced horizontal scaling.

Tools
LaravelRedisAWS ELBMySQLKubernetesDocker
Outcome

Reduced response time from 15 seconds to roughly 750ms, increased concurrent-user capacity toward 10,000+, and stabilized uptime around 99.9%.

Problem

The HRMS platform had high MSSQL licensing cost, slow payroll and attendance queries, and limited integration with modern services.

Solution

Planned a chunk-based migration, redesigned schemas, normalized data, tuned MySQL 8 queries, and added cache-backed processing for heavy workflows.

Tools
PHPMSSQLMySQL 8RedisLaravel QueuesKafka
Outcome

Completed the 90GB+ migration with zero data loss, reduced query times from 30 seconds to under 2 seconds, and cut operating cost by 60%.

Problem

Manual Laravel and React deployments across multiple servers took 2-3 hours and introduced configuration drift between environments.

Solution

Implemented GitHub Actions pipelines for build, test, SSH deployment, migrations, cache clearing, and consistent multi-server releases.

Tools
GitHub ActionsSSHLaravel EnvoyNode.jsPM2MySQL
Outcome

Reduced deployment time to 5-10 minutes per server and removed repeated manual release errors.

Problem

Chat, notifications, presence, audio, and video features needed to work for many concurrent users without dropped state or message loss.

Solution

Used Laravel Echo, Redis pub/sub, Pusher, Agora, room/session management, and reconnection handling for stable real-time behavior.

Tools
Laravel EchoPusherRedisAgoraWebSocketsReact
Outcome

Delivered dependable real-time chat, presence, notifications, and audio/video calling for collaborative workflows.

Problem

SMS, push, and email delivery became slow and unreliable under high volume, causing queue backlogs and delayed communication.

Solution

Separated channels, added queue-based asynchronous processing, provider throttling, retries, delivery monitoring, and failure dashboards.

Tools
Laravel QueuesRedisFCMSMTPSMS GatewayAWS SES
Outcome

Improved delivery reliability for high-volume SMS, push, and email notifications while making failures visible and recoverable.

Problem

Repeated requests, brute-force attempts, race conditions, and unoptimized queries created availability and security risk.

Solution

Added rate limiting, validation, queue locks, caching, query optimization, WAF rules, and suspicious-activity monitoring.

Tools
Rate LimitingRedisValidationAWS WAFQueue LockingMonitoring
Outcome

Improved request control, thread safety, endpoint security, and production stability under heavy traffic.
