Backend-heavy Laravel work. Every project: clean architecture, fully documented, Postman collection on delivery.
Versioned APIs with Sanctum authentication, Spatie roles and permissions, rate limiting, consistent error responses, and full Postman documentation. From a 5-endpoint MVP to a complete production API backend.
Multi-tenant SaaS with team management, Stripe or Cashier subscription billing, usage limits, queue-driven jobs with Horizon, FilamentPHP admin panel, and scalable MVCS architecture built to grow.
Custom POS systems, inventory management, WooCommerce integrations, order tracking, and payment gateway integrations — Stripe, PayPal, SSLCommerz, and more.
N+1 query detection, Redis caching, Horizon queue tuning, database indexing, and full backend audits. I fix slow Laravel applications — not just describe the problem.
Real work. Real clients. Real code in production.
Multi-tenant SaaS POS and inventory management system with WooCommerce sync, fraud detection alerts, and comprehensive sales reporting. Built for a retail business.
European-standard payslip generation system. Pappers API + Mon Entreprise API integration, multi-tenancy, SSO, automated tenant provisioning. Deployed on Docker and Kubernetes for a French client.
Variant-based inventory e-commerce with Pathao courier API integration for real-time delivery tracking and full order management.
Cylinder inventory and POS for an LPG company. Stock tracking, sales reporting, and delivery management built on Laravel 11 with FilamentPHP admin.
No vague estimates. No hidden costs. No disappearing after delivery.
Message via WhatsApp or email. Describe your project — API, SaaS, e-commerce, optimization. I respond within 4 hours with questions if needed.
Not a range. Not an estimate. A number and a date, agreed before a single line of code is written. You approve it — then we start.
You see progress through the build. Test on a staging environment before delivery. No surprises at the end.
GitHub repo, README, Postman collection, database schema. Bug fix support included after delivery. You're never left alone with code you don't understand.
Fixed per project — never hourly. Simple REST API from $50. Full API with Sanctum, Spatie, and Postman docs from $150. SaaS platforms from $300. E-commerce backends from $200. My rates are 50–70% lower than a US or UK developer. Same code quality — lower overhead because I'm in Bangladesh.
On Upwork you pay platform fees on top of hourly rates. On Toptal you pay agency premiums. With me, you get a fixed price, direct communication, and the same developer from start to finish. No middlemen. No random contractor assignments. You know exactly who is writing your code.
Simple API (3–5 endpoints): 3–5 days. Full REST API backend: 1–2 weeks. SaaS platform: 3–6 weeks. You always get a fixed delivery date agreed upfront — not an estimate that slips.
Laravel 10, 11, 12, and 13. Every project uses Sanctum for authentication, Spatie for roles and permissions, proper exception handling, MVCS architecture, and follows official Laravel best practices. No outdated patterns, no copy-paste code.
Yes — US, UK, Europe, Middle East, and Australia. All communication in English. I work via WhatsApp, email, or Slack and adapt to your time zone for meetings. Payment via PayPal, Wise, or bank transfer.
Code pushed to GitHub, a README with local setup instructions, a Postman collection covering every API endpoint, database migration files, and post-delivery support for any bugs. You own 100% of the code with no lock-in or ongoing fees.
Describe what you need — API, SaaS, e-commerce backend, optimization. I'll reply within 4 hours with a clear scope and fixed price. No commitment to respond.
