About Jay Gajjar

I am a senior software engineer in Ahmedabad, India. I build Laravel and PHP systems, WordPress sites and landing pages, and do the SEO that gets them found, for clients worldwide.

I build the back office: trading platforms, multi-company ERPs, and the integrations that connect them to the systems a business already runs on.

I joined Precise Developers in Ahmedabad as an intern in January 2023 and became a Senior Software Engineer in under three years. Most of my work is PHP 8, Laravel and MySQL.

What I care about most is data that stays correct under pressure: transactions and row-level locks so two people never get the same invoice number, and idempotent jobs so a retry never runs an operation twice.

Today I lead one or two junior developers, review their pull requests, and work with clients directly, from the first requirement to production support.

What I hold the work to

Correctness: Invoice numbers, balances and stock are protected by transactions and row-level locks, not by hoping two users never click at once.
Reliability: Jobs are idempotent and safe to retry, failed jobs can be recovered, and concurrency is capped where money moves.
Security: Signed requests, role-based access and company-level data isolation are designed in from the start.
Collaboration: Requirements are agreed with the client before code, and juniors get small, reviewable tasks with real feedback.

What I take on as a freelancer

Most of my freelance work falls into four groups. Each links to the services inside it, with what is included, how the work runs and the questions clients usually ask.

Laravel and PHP development: custom applications, APIs, CodeIgniter and Perfex CRM work, upgrades and maintenance.
WordPress: custom sites, plugins, WooCommerce, speed, security and care plans.
Websites and landing pages: hand-coded pages that load fast and are ready for search from day one.
SEO and content: technical audits, on-page SEO, keyword research and articles like the ones on this blog.

I work alone, so you deal directly with the engineer who writes the code. Agencies can also work with me white-label.
