With 13+ years of experience in PHP (Symfony, Laravel), ERPNext/Frappe, Python, and DevOps, I specialize in taking over existing systems that need stability, performance, and long-term maintainability — the projects other developers find too messy or risky to touch.

• ERPNext / Frappe customization, integrations, and deployment
• REST API development & third-party integrations
• Performance tuning with Redis, Elasticsearch, and query optimization
• DevOps: Docker, AWS, DigitalOcean, Linux, CI/CD, RabbitMQ queues & schedulers

• Built and stabilized real-time systems (WebRTC) across web and iOS
WHY CLIENTS KEEP ME LONG-TERM

With 15+ years as a Principal and Senior Engineer, I build complex, scalable web applications — and I leverage AI tools daily to ship faster without cutting corners on architecture.
What I specialize in:
• AI-augmented development — GitHub Copilot, Cursor, Claude, and ChatGPT are part of my actual workflow. I use them to accelerate development, improve code quality, and reduce debugging cycles — not as a gimmick.
• AI integrations — OpenAI API, LLM-powered features, AI chatbots, and intelligent automation embedded into production applications.
• Multi-tenant SaaS architecture — tenant isolation, RBAC, subdomain routing, scalable service layers (Laravel Tenancy, custom implementations).
• Backend systems that scale — Laravel, Symfony, Java Spring Boot, Node.js/Express.js, NestJS.
• Legacy modernization — Zend, CodeIgniter, CakePHP, VB.NET/ASP.NET → modern Laravel or Node.js, with zero downtime migrations.
• Complex API design — RESTful and GraphQL APIs, third-party integrations (payment gateways, CRMs, data providers, AWS services).
• React / Vue frontends — when the project demands a complete full-stack build.
• Cloud & serverless — AWS (Amplify, Lambda, S3, EC2), pipeline automation, multi-environment deployments.
What I've shipped:
30+ production applications across startups, agencies, and enterprise clients — multi-tenant CRMs, hospitality and inventory management systems, real estate platforms, e-commerce solutions, headless WordPress/Next.js sites, AWS serverless applications, and call centre tooling across clients in Europe, USA, Malaysia, and the Gulf.
Why clients come back:
I've led teams of 8+, owned full project delivery end-to-end, and managed client communication directly — sprint planning, demos, technical scoping. You get a principal-level engineer who understands the business problem, not just the ticket.
Available for: Long-term contracts · Complex full-stack builds · SaaS product development · AI feature integration · Team augmentation · Technical leadership
Timezone: UTC+5 (PKT) — overlap available with EU, Gulf, and AU/NZ hours.
Message me to schedule a quick discovery call — no commitment, just clarity.
