I can’t recommend Abdur enough. He did an outstanding job developing a highly complex application for me from scratch, which involved livestreaming and monetizing pay-per-view live events. His technical expertise, clear communication, and ability to handle challenges made the whole process smooth and successful. If you’re looking for someone reliable and highly skilled, Abdur is your man!!.

🏆 Top Rated | 100% Job Success | Senior SaaS Engineer & Team Lead at Aqren.dev
🥇 Trusted by startups, enterprises & global SaaS companies
I’m Abdur Rahman — a full-stack engineer and technical lead specializing in scalable, production-ready SaaS platforms. I architect, build, deploy, and maintain complete applications with a strong emphasis on multi-tenancy, performance, reliability, and long-term maintainability.
Over the past few years, I’ve delivered complex systems for startups, enterprise clients across Europe and the US, and multiple SaaS companies. At Aqren.dev, I lead architecture, guide a small engineering team, and ship high-quality, production-grade software on a consistent basis.
I don’t just write code — I design systems that last.
🟢 What I Build
I specialize in multi-tenant SaaS, serverless platforms, and data-heavy applications, including:
- Multi-tenant SaaS (RLS, tenant isolation, permissions, audit logs)
- E-commerce & payment systems (Stripe Connect, fees, onboarding flows)
- Real-time platforms (LiveKit, WebSockets, Supabase Realtime)
- AI-powered applications (OpenAI, Gemini, custom LLM pipelines)
- Complex workflow engines (dynamic forms, automation, validations)
- Dashboards for enterprises (analytics, scheduling, reporting)
- Marketplaces, IoT systems, booking & service-based platforms
If you need something complex, scalable, and built to grow, that’s my zone.
🟢 Backend Engineering (Core Expertise)
I build highly scalable, clean, and maintainable backend systems:
- Node.js / Express / Fastify
- PostgreSQL + Prisma (optimized schemas, indexes, migrations)
- Supabase (RLS, Edge Functions, RPCs, Realtime)
- Redis caching, queues, rate-limiting
- Kafka, RabbitMQ, Redis Queue
- Stripe & Stripe Connect (payouts, fees, subscriptions)
- Authentication (Supabase Auth, Firebase Auth, Auth.js, JWT)
- LLM workflows: OpenAI, Anthropic, Gemini
-Clean architecture, layered validation, consistent error handling
🟢 Frontend Development
I convert complex systems into beautiful, intuitive interfaces:
- React, Next.js, TypeScript
- TailwindCSS, MUI, SCSS
- Zustand, Redux, TanStack Query
- PWA & SEO optimization
- Framer Motion for smooth, modern animations
- Fast, responsive, and optimized for real users.
🟢 DevOps & Deployment
I own full production infrastructure end-to-end:
- AWS (EC2, S3, CloudFront, SES, Lambda, Amplify)
- CI/CD with GitHub Actions / GitLab CI
- Docker, Linux servers, Nginx, Cloudflare
- Vercel / Netlify deployments
- Automated environments: dev → staging → production
🟢 Testing & Reliability
- Jest / Vitest (unit + integration)
- Cypress (e2e + component)
- Load & performance testing
- Monitoring + error reporting
🟢 Let’s Build Your Product — Properly
If you need someone who can:
- understand business logic
- design the right system architecture
- write scalable, production-grade code
- integrate payments, auth, automation
- lead a team or entire technical delivery
- deploy and maintain a stable product
…then you’re in the right place.
I’d love to discuss your project and show how I can help.
Best regards,
Abdur Rahman
