I'm a software developer with 10+ years of experience in web development, with a strong focus on PHP and Laravel. I build backend systems and business applications that are maintainable, secure, integration-friendly, and designed to grow with business needs.

My work spans SaaS platforms, multi-tenant systems, procurement and auction workflows, legal practice management, student marks/reporting systems, payment integrations, and cloud deployments.

I enjoy working across the full development lifecycle: understanding business requirements, designing database schemas and application architecture, implementing APIs and workflows, integrating external services, debugging production issues, and deploying applications.

• Laravel and modern PHP application development
• REST API design, authentication, authorization, and third-party integrations
• Multi-tenant SaaS architecture and tenant-aware data access
• MySQL schema design, query optimization, and data integrity
• Maintainable application structure, testing, and production reliability
• Cloud deployment and operational troubleshooting

AI/LLM is an additional area of interest, including local language models and retrieval-augmented generation (RAG). My primary professional focus remains Laravel and backend engineering.

• Primary: PHP, Laravel
• Node.js, Express.js, TypeScript
• RESTful APIs, middleware, validation, authentication and authorization
• Background jobs, queues, scheduled tasks, notifications, webhooks
• Third-party API and payment gateway integrations

• Eloquent ORM and database migrations
• Service classes and modular application design
• Form Requests, API Resources, Policies, Gates and middleware
• Queue workers, events, listeners, notifications and scheduled commands
• Multi-tenancy and tenant-aware application workflows
• Automated testing with PHPUnit and Pest

• MySQL / MariaDB
• PostgreSQL
• MongoDB
• Database schema design, indexing, transactions and query optimization
• Tenant database isolation and workspace-scoped data access

• React.js
• TypeScript and JavaScript
• Inertia.js
• Vue.js
• HTML, CSS, Bootstrap and Tailwind CSS

• AWS EC2, RDS, S3, Cognito, SES and SNS
• Docker
• Linux / Ubuntu
• Nginx and Caddy
• Git and GitHub
• Composer, npm and REST API testing tools
• Deployment, environment configuration, logging and troubleshooting

• Ollama and local LLM experimentation
• Retrieval-Augmented Generation (RAG)
• Vector search and embeddings
• Qdrant and ChromaDB
• Integrating AI capabilities into existing applications

The following section summarizes project domains and engineering experience. Link each item to a public repository or case study only when the corresponding source code or documentation is available publicly.

Focus: Laravel · React · Inertia.js · TypeScript · Multi-tenancy

A legal practice management platform designed around organizations, tenant workspaces, firms/branches, and legal case workflows.

Areas of work include:

• Central platform and tenant provisioning
• Tenant-specific database architecture
• Organization and workspace separation
• Client and case management
• Court registry and hearing management
• Legal document management and storage foundations
• Tasks, reminders and notifications
• Dashboard, operational overview and workspace-scoped search
• Security, reliability and end-to-end verification

The architecture uses a central platform layer and tenant databases, with logical firm/branch partitioning inside a tenant workspace.

Focus: Node.js · Express · TypeScript · Prisma · MySQL · AWS

A multi-tenant procurement and auction backend supporting business workflows such as:

• Supplier management
• Auction events and bidding
• Request for Quotation (RFQ) events
• Purchase Requisitions (PR)
• Goods Receipt Notes (GRN)
• Advance Shipping Notices (ASN)
• Invoices, contracts and agreements
• Authentication and role-based access
• File uploads and AWS S3 integration
• Notifications and real-time events
• External ERP/SAP integration concepts and data exchange

Although this project uses a Node.js backend, it demonstrates experience with enterprise workflows, integrations, multi-tenant design and backend architecture.

Focus: Laravel · PHP · MySQL

A student marks and reporting application involving student records, marks data, database configuration, and deployment-related work.

Potential case-study areas include:

• Student and academic data management
• Marks entry and reporting
• Database schema and validation
• Environment configuration and hosting

Add repository links and specific features after confirming which implementation details are publicly shareable.

Focus: PHP / Laravel · Payment API integration

A payment gateway integration project. See the repository for the exact implementation, supported flows, setup requirements and current maintenance status.

Repository: narendraraghuwanshi/phonepe

Experience working with external systems and application integrations, including:

• GoHighLevel contact integration from CodeIgniter/PHP forms
• Tally data synchronization planning for sales, purchases, inventory, customers, outstanding balances and GST
• AWS services for authentication, storage, databases and email delivery
• File upload workflows and object storage
• API-driven workflows and operational reporting

These are project/workflow areas; add a public repository or case study only where the implementation can be shared.

Optional specialization: Local LLMs · Ollama · RAG · Qdrant · ChromaDB

Exploring ways to connect language models with domain-specific documents and business workflows, including legal-document retrieval and question answering. This is a secondary interest rather than my main developer positioning.

• Readable code: prefer clear names, cohesive classes and understandable control flow.
• Maintainable architecture: use patterns that solve real problems without unnecessary complexity.
• Security first: validate input, enforce authorization and keep secrets out of source control.
• Data integrity: design schemas and transactions around business rules.
• API consistency: use predictable responses, clear validation errors and documented contracts.
• Testing: cover important business logic and critical application workflows.
• Operational readiness: consider logging, configuration, queues, deployment and failure handling.
• Tenant isolation: ensure tenant-specific data access is deliberate and tested.

• Building robust Laravel applications and REST APIs
• Improving SaaS and multi-tenant application architecture
• Developing reusable integrations and maintainable backend modules
• Improving automated test coverage and code quality
• Contributing to useful PHP/Laravel open-source projects
• Exploring AI/LLM integrations when they provide practical business value

• Senior Laravel Developer opportunities
• Senior PHP / Backend Developer roles
• Laravel SaaS and multi-tenant platform development
• API development and third-party integrations
• Remote contract work and international collaboration
• Open-source collaboration around PHP and Laravel
