Production-grade systems built for scale, reliability, and growth.
I partner with tech founders, growing engineering teams, and businesses to build high-throughput backends, complex multi-tenant SaaS platforms, resilient APIs, and optimized database infrastructure.
01 — Capabilities
What I build & architect.
Focused technical disciplines with hands-on production engineering in high-concurrency environments since 2022.
SaaS Platform & Web Application Development
I design and build multi-tenant SaaS platforms that support thousands of users without slowing down. Your users get isolated, secure workspaces. Your team gets a clean, maintainable codebase they can build on for years — not a pile of technical debt to fight through every sprint.
- Multi-tenant SaaS — each client's data stays completely separate
- Role & permission systems — who sees what, fully controlled
- Subscription billing & automated invoicing built in
- Admin dashboards your ops team can actually use
REST API Development & Third-Party Integrations
Your mobile app, web frontend, or partner platform needs a backend API it can rely on. I build fast, secure, versioned APIs that don't break when traffic spikes — and integrate with any third-party service your business depends on, from payment gateways to courier networks.
- Secure API with login, token auth & role-based access
- Payment gateway integration — Stripe, SSLCommerz, bKash
- Courier & logistics sync — Pathao, Steadfast, RedX
- WhatsApp & Facebook API automation pipelines
Performance Optimization & Server Infrastructure
Your app is slow, jobs are failing, or the server crashes under load? I audit your queries, queues and server setup, then fix the real bottlenecks.
- Slow query audit & database index fixes — measurable speedup
- Background job queues that don't drop or lose work
- Docker + CI/CD setup — deploy without downtime
- Written performance report before & after every fix
AI-Powered Features & Intelligent Automation
Your product can do more — automatically. I add AI capabilities to your existing Laravel backend: from LLM-powered content pipelines and intelligent scoring engines, to chatbots and automated decision flows. All shipped as reliable, monitored production jobs — not one-off scripts.
- OpenRouter / OpenAI / Gemini integration in your existing app
- AI fraud & risk scoring engines — COD, payment anomaly detection
- WhatsApp & Telegram bots with AI-powered response flows
- Queued LLM pipelines — retried, monitored, cost-controlled
02 — Engagement Models
How we collaborate.
Structured, predictable working models aligned with your project lifecycle and engineering velocity.
Full-Cycle Project Delivery
End-to-end architecture and implementation of SaaS platforms, custom backends, or API subsystems with defined milestone phases.
Best for: New products, major feature launches & MVP-to-scale rewrites- Clear technical specifications & roadmap
- Milestone-based delivery & staging reviews
- Direct Git repository handover
Performance & Scale Sprint
A focused, intensive 1- to 2-week engagement diagnosing and resolving critical bottlenecks in live production environments.
Best for: Slow apps, high server costs, crash mitigation & traffic spikes- Database query indexing & N+1 eradication
- Redis queue stabilization & worker tuning
- Measurable latency benchmark reports
Advisory & Fractional Engineering
Ongoing technical guidance, PR code reviews, system design oversight, and architectural leadership embedded in your team.
Best for: Growing teams needing technical oversight and mentorship- Architectural review of schema & API decisions
- Strict code review standards (PSR-12, static analysis)
- Async Slack/GitHub access & weekly syncs
03 — Standards
The engineering process.
Every project adheres to rigorous software craftsmanship principles and direct collaboration.
Requirements analysis, data modeling, API contract definition, and constraint mapping before writing code.
Clean PSR-12 code, service classes, domain actions, and automated unit tests committed directly to GitHub.
Interactive staging verification, edge case testing, database seeding, and load benchmarking.
Docker Compose setup, migration scripts, Postman workspace, and 100% intellectual property ownership transfer.
04 — FAQ
Frequently asked questions.
How are project scopes and investments structured?+
Every engagement begins with an initial technical discovery to define the scope, system architecture, and deliverables. Engagements are structured as milestone-based phases or monthly advisory retainers — never unpredictable, open-ended hourly billing.
Do you collaborate with distributed teams across time zones?+
Yes. I have been collaborating with clients and engineering teams across France, the United States, the UK, Europe, and the Middle East since 2022. All documentation and communication is conducted in English via Slack, GitHub, or video calls with daily asynchronous updates and flexible meeting overlap.
Who owns the intellectual property and code?+
You own 100% of the code, database schemas, configuration files, and documentation from day one. Commits are pushed directly to your organization's private GitHub or GitLab repository with no vendor lock-in.
What does the technical handover include?+
You receive clean, well-tested code adhering to modern standards (PSR-12, typed PHP 8.3+), automated database migrations and seeders, a complete Postman collection covering every API endpoint, Dockerized local environment instructions, and post-deployment stabilization support.
How do we get started?+
Send an email or message with a brief summary of what you are building or the technical challenges you are solving. I typically reply within four hours to schedule a discovery call or provide initial technical thoughts.
Have a system to build or optimize?
Share your technical requirements or existing bottlenecks. I typically respond within 4 hours with technical feedback and next steps.
