React & Node.js Developer
Subhan is an excellent React.js and Node.js developer. He delivered high-quality, clean code, communicated well and completed the project on time. Strong skills in React, Node.js, JavaScript, TypeScript, REST APIs, MongoDB, Git and full-stack development. Reliable, professional, and easy to work with. Highly recommended, and I'd gladly hire him again.

Fix Meilisearch Indexing Issue in Ruby on Rails App
Great working with Subhan. He quickly fixed the Meilisearch indexing issue in our Ruby on Rails app and made sure everything was working properly. Communication was smooth and the task was completed on time.
Would recommend him for Rails, Meilisearch and backend debugging tasks.

About Subhan
SaaS Developer | Build, Scale & Optimize Products
100%
Job Success
Lahore, Pakistan - 10:28 pm local time
With 10+ years of experience, I work across the full product lifecycle — from MVP development and new features to API development, database optimization, backend architecture, performance improvements, third-party integrations, and AI-powered automation.
Your product doesn't usually break when you have 100 users. It breaks when you have 10,000.
Traffic spikes. APIs slow down. Database queries become bottlenecks. Infrastructure costs climb. Integrations become unreliable. Features that worked perfectly during MVP suddenly become expensive to maintain.
That's where I come in.
What I can help you with:
SaaS development — MVPs, new products, features, and existing applications
Backend & API development — REST, GraphQL, integrations, architecture, and performance
Scaling & performance — slow APIs, database bottlenecks, high traffic, and production issues
Database optimization — PostgreSQL, MySQL, MongoDB, query optimization, and architecture
Third-party integrations — Stripe, PayPal, QuickBooks, and other APIs
AI & automation — LLM integrations, AI agents, automated workflows, and AI-powered SaaS features
Product modernization — improving existing codebases without unnecessary rewrites
Cloud & infrastructure — AWS, Docker, CI/CD, and production deployments
Results I've delivered:
eCommerce platform — 1M+ users
Reduced load time from 3.2s to 1.1s
Improved conversion by 18%
HR analytics platform — 70K+ users
Automated manual workflows
Significantly reduced report generation time
Improved operational efficiency through workflow automation
Automotive data platform
Optimized database queries and reduced query times by 60%
Enabled faster access to real-time insights
SaaS products
Built AI/LLM-powered workflows and agentic automation
Helped automate operational processes without adding headcount
My technology stack:
I don't limit myself to a single framework. I choose the technology that fits the product, existing architecture, timeline, and long-term goals.
Frontend: React.js, JavaScript, Material UI, Ant Design
Backend: Ruby on Rails, Node.js, Elixir/Phoenix
Databases: PostgreSQL, MySQL, MongoDB, MSSQL
Cloud & DevOps: AWS, Docker, Jenkins, CI/CD
APIs & Integrations: REST, GraphQL, Stripe, PayPal, QuickBooks, 100+ third-party integrations
AI & Automation: LLM integrations, AI agents, agentic workflows, workflow automation
Why founders work with me:
Product-focused: I think beyond individual tickets and understand how technical decisions affect the product.
Root-cause focused: I fix the underlying problem instead of repeatedly treating symptoms.
Built for scale: Architecture decisions consider what happens when your users and traffic grow.
Practical: I avoid unnecessary rewrites and recommend the simplest solution that solves the actual problem.
Direct communication: You work directly with me — no unnecessary layers or communication overhead.
Outcome-driven: The goal is faster, more reliable, maintainable software — not simply more lines of code.
Whether you're building a SaaS from scratch, adding a major feature, dealing with a slow production system, or trying to figure out why your application isn't scaling the way it should, I can help.
Tell me what you're building, what's currently not working, or what you're trying to improve. I'll help you identify the problem and the most practical way forward.
