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 four years of hands-on production experience in high-concurrency environments.
SaaS & Web Platform Architecture
Full-lifecycle engineering of multi-tenant platforms, complex business workflows, role-based permission hierarchies (Spatie), and operational admin systems built for long-term maintainability.
- Multi-tenant database tenancy (schema vs database segregation)
- Clean MVCS & Action/Service domain layer architecture
- Audit logging with event observers & telemetry tracking
- Subscription billing & automated invoicing lifecycles
High-Throughput REST APIs & Integrations
Secure, versioned APIs designed for web, mobile apps, and third-party consumers. Bulletproof webhook handling with idempotency and replay protection.
- Stateless Sanctum token authentication & OAuth flows
- Payment gateway pipelines (Stripe, SSLCommerz, bKash)
- Courier & logistics sync (Pathao, Steadfast, RedX)
- Complete Postman collections & OpenAPI specifications
Database Tuning, Queues & DevOps
Eliminating production bottlenecks: fixing slow queries, configuring Redis Horizon queue workers, preventing OOM crashes, and zero-downtime container deployments.
- MySQL EXPLAIN analysis, composite indexes & query fixes
- Redis queue orchestration, Horizon metrics & Supervisor
- Multi-stage Docker containerization & Kubernetes manifests
- GitHub Actions CI/CD pipelines with automated tests
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 senior 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 four years of experience collaborating with clients and teams in France, the United States, the UK, Europe, and the Middle East. 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.
