Sudheer Shrivastava

I’m a results-driven Senior PHP / Laravel Developer with 7+ years of experience designing and delivering scalable, high-performance web applications using PHP 7.x, Laravel (8-13), MySQL, and RESTful APIs. I bring deep expertise in MVC architecture, Eloquent ORM, Redis caching, AWS (EC2/S3), and PHPUnit testing, delivering secure, maintainable systems across fintech, SaaS, event management, and enterprise domains.

I’ve proven impact on performance and reliability—reducing database query execution time by 35-40% through indexing, eager loading, and Redis caching. In my most recent role, I diagnosed and resolved critical production defects in Laravel banking systems, improving mean time to resolution by ~30% while reducing page-load errors by ~25%.

I build with SOLID principles, OOP design, and TDD in mind, using PHPUnit to drive strong regression coverage and production readiness. I also apply middleware, queues, and events patterns to decouple business logic and improve maintainability, alongside careful code reviews and standards enforcement across development teams.

Across engagements, I’ve architected and maintained Laravel applications serving 50,000+ active users with 99.9% uptime on AWS EC2, and integrated complex third-party services including Stripe, Razorpay, PayU, SMS APIs, and OpenAI APIs. My projects reflect this end-to-end focus—from multi-tenant AI captioning SaaS using OpenAI Whisper and Stripe subscriptions to high-throughput SMS delivery platforms with AWS queue-based processing.
