Wordpress Website Customization
Talha did an excellent job helping configure and refine our WordPress ListingPro directory site. He quickly identified setup issues, installed the correct importer plugin, and worked through the initial listing architecture to get everything running smoothly. Communication was prompt, the work was efficient, and he showed good problem-solving ability when troubleshooting the import feature.
I’d gladly work with him again on future MontanaPower.com development tasks. Highly recommended.

Job Success
Lahore, Pakistan - 7:22 pm local time
With 8+ years of industry experience, I help startups and growing businesses build scalable, high-performance web applications using the MERN stack, Next.js, and modern API-driven architecture. I take complex ideas and translate them into polished, production-ready MVPs, SaaS platforms, and internal tools built for long-term growth.
I've supported a wide range of startups and growing companies across SaaS, fintech, real estate, and e-commerce, helping them launch reliable digital platforms and scale existing products with clean, maintainable architecture.
One of my strongest projects was Mavericks Motors. The founder needed an investor-ready SaaS MVP after delays from previous developers put the launch at risk. In just 1.5 months, we delivered a pixel-perfect platform using Nest.js, Node.js, MongoDB, and AWS, including four AI-powered chatbots built with LangChain and vector search for real-time, intelligent support. The result was an on-time launch and restored investor confidence.
What I Do:
I design and develop modern SaaS platforms, custom web applications, internal tools, dashboards, and API-driven systems using React.js, Next.js, Node.js, Express.js, and MongoDB. Whether it's building an MVP from scratch, integrating third-party APIs, or scaling an existing product, I focus on delivering reliable, secure, production-ready solutions.
My work includes:
Custom web applications and SaaS platforms
MVP development for startups and fintech
CRM and ERP systems
AI-powered platforms and chatbots
Marketplace and real estate platforms
API development and third-party integrations
Tech Stack:
Backend: Node.js, NestJS, Express.js, Laravel, REST APIs, Microservices
Frontend: React.js, Next.js, Vue.js, TypeScript, Tailwind CSS
Databases: MongoDB, PostgreSQL, MySQL, Supabase
AI and Automation: OpenAI, LangChain, RAG systems, AI agents, n8n
Cloud and DevOps: AWS, Docker, CI/CD, Git
Why Clients Work With Me:
I don't just write code. I understand the business goal behind the product. Clients hire me when they need someone who can think clearly, communicate well, solve real technical problems, and deliver software that's ready for users and growth.
My process is focused on clean architecture, efficient workflows, and long-term maintainability. Whether you need a new MVP, an AI-powered system, or a complex product rebuild, I can help you move from idea to launch with confidence.
Send me a message with your idea, and I'll help you break it into a launch-ready MVP.
