Selected Projects
Three systems that show how the work scales under pressure.
Each project was chosen for architectural depth, operational consequence, and measurable business impact.
Expertise
Not a list of tools. A set of systems I know how to make hold.
The work spans backend architecture, operational software, integration-heavy ecommerce, and the performance discipline needed to keep them useful.
API & Integration Engineering
Connecting payment, shipping, marketplace, CRM, ERP, and event systems into a single reliable operating flow.
10+ marketplace integrations and multiple logistics/payment plugins.
Ecommerce Infrastructure
Scaling WooCommerce and custom commerce operations for order-heavy businesses that cannot tolerate operational drift.
1,000+ daily orders sustained on minimal infrastructure for Aso Kala.
Logistics & Order Management Systems
Building dispatch, pricing, shipping, and order orchestration systems with real operational constraints in mind.
Tipax, T-Express, T-Next, and Logistics Bazaar portal delivery.
Performance Optimization
Profiling bottlenecks, hardening caching layers, and reducing infrastructure waste without sacrificing reliability.
Redis, Memcached, Docker, LiteSpeed Cache, and crawler-assisted pricing systems.
Laravel / PHP Engineering
Shipping pragmatic backend systems in PHP with discipline around testing, delivery velocity, and maintainability.
Laravel, Filament, custom PHP platforms, PHPUnit, and 160+ shipped web builds.
Terminal Mode
A concise way to say what the work is about.
The best backend engineers reduce noise. This section leans into that: sparse, factual, and closer to an operating console than a personal bio wall.
Experience
A timeline shaped by logistics, commerce, healthcare, and internal systems.
The recent years are deliberately more visible because they show the current operating range: team leadership, integrations, ERP design, and order-heavy platforms.

Services
Consulting and delivery where architecture has direct business consequences.
The engagement model is pragmatic: diagnose quickly, define the real constraint, and either design the system or help ship the fix.
