I build enterprise platforms that last — not prototypes that get rewritten. My longest engagement is 6+ years with a single client, growing from 4 modules to a 9-module field operations platform. That's the kind of work I'm looking for. Recently I've been focused on AI systems engineering — RAG pipelines, LLM API integration, and WhatsApp-based AI agents running in production on SaaS platforms. 𝐖𝐡𝐚𝐭 𝐈 𝐁𝐮𝐢𝐥𝐝 Complex, long-term platforms — not one-off fixes or quick integrations. My clients are typically building something serious: a multi-tenant SaaS, an enterprise operations platform, or a system where AI needs to work reliably in production, not just in a demo. They need an architect who can own the technical direction end to end, communicate clearly with non-technical stakeholders, and stay consistent over years — not months. If you have a well-defined short-term task, I'm probably not the right fit. If you're building something that needs to scale and last, let's talk.

50+ SaaS products designed. I'm a SaaS UI UX designer and dashboard designer for B2B web apps Figma, data-first. Before I design anything, I read your analytics. Your users drop off somewhere. I find it first. What I work on: → SaaS dashboard design & web app UI UX → B2B SaaS product design (onboarding, paywalls, user flows) → SaaS website & landing page design → Mobile app design (iOS & Android) → Design systems & Figma component libraries → Developer-ready handoff (tokens, specs, documentation) How I work: I don't start with Figma. I start with your data. Mixpanel, Clarity, PostHog, Amplitude I audit where users drop off before a single wireframe gets drawn. Every decision is tied to a real problem in your analytics. Not assumptions. Data. Who I work with: SaaS founders at early to growth stage. Non-technical founders building from scratch. Product teams that need a SaaS specialist, not a generalist. What you get: Clean Figma files. Named components. Design tokens. Interaction specs. Dev documentation. Designs your dev team can actually build from, not just screens that look good in a presentation. Results: → 50+ SaaS products designed → Avg +28% activation improvement post-redesign → 4.9/5 on Clutch | 750+ verified reviews on other marketplaces → Trusted by SaaS founders across US, UK & Europe If your users are dropping off, conversion is stuck, or your product feels hard to use, message me. Tell me what's broken.

Many businesses do not need just another developer. They need a technical partner who can understand the real business problem, simplify the requirements, choose the right architecture, and build a custom software solution that can grow with the organisation. I’m Aqeel Haider, Founder of Machine Intelligence 6. For the last 12+ years, I’ve helped businesses design and build custom SaaS platforms, marketplaces, portals, internal systems, and scalable web applications. Over the years, I have worked with 100+ clients and delivered custom software solutions across the USA, Canada, Australia, UAE, Europe, and Pakistan. My work includes SaaS platforms, marketplaces, CRM systems, business portals, automation tools, cloud applications, and internal systems for growing businesses. Businesses often come to me when they are facing challenges like: • They have an idea for a custom SaaS platform, marketplace, portal, or internal system, but are not sure how to structure it. • Their existing software is slow, outdated, or difficult to maintain. • Their business still depends on spreadsheets, manual work, or disconnected tools. • Their previous developer left behind messy code, poor documentation, or an unfinished product. • They need web, mobile, admin, backend, and integrations to work together as one complete system. • New requirements keep coming up, and they need a technical partner who can think through the business logic, not just complete isolated tasks. This is where I help. Many clients come with an idea, an unfinished product, or a business process that needs to be turned into a proper software system. Sometimes the requirement is clear from day one. Sometimes it becomes clear after we start mapping the workflows, user roles, admin needs, mobile experience, and business logic. I don’t just write code. I help clarify the product, define the modules, plan the architecture, and build the web, mobile, admin, and backend systems needed to support the business. What I can help you build: • Custom SaaS platforms • Online marketplaces • Business portals and client portals • Admin dashboards and internal tools • Web and mobile applications • CRM, ERP, LMS, and workflow systems • Booking, reporting, and subscription-based platforms • API integrations and third-party system connections • Cloud-based applications and scalable backend systems • Automation tools for business operations My focus is on building systems that are practical, scalable, and easy to manage. Whether you need a new product built from scratch, an existing system improved, or a business process converted into software, I can help you plan and build it properly. My working process: 1. Understand the business problem Before writing code, I first understand the business goal, users, workflows, and the problem we are trying to solve. 2. Plan the solution I help define the modules, user roles, features, data flow, integrations, and technical architecture. 3. Design the experience For larger products, we create user flows, wireframes, and admin/client journeys before development begins. 4. Build the system My team and I develop the backend, frontend, admin panel, APIs, mobile app, integrations, and cloud infrastructure as required. 5. Test and improve We test the product for bugs, performance, user experience, responsiveness, and business logic. 6. Launch and support After launch, we can continue improving the system, adding features, monitoring performance, and supporting long-term growth. This process helps reduce confusion, avoid surprise costs, and make sure the final product actually supports the business. Technologies I work with: • Frontend: React, Next.js, Vue.js, JavaScript, TypeScript • Backend: Node.js, Express, Java Spring Boot, PHP/Laravel, Python/FastAPI, Java Spri • Mobile: React Native • Databases: PostgreSQL, MySQL, MongoDB, Firebase • Cloud & DevOps: AWS, Azure, Docker, CI/CD, Linux servers, Nginx • Integrations: Stripe, PayPal, Clerk, Auth0, Google APIs, CRM/ERP APIs, third-party platforms • AI & Automation: OpenAI APIs, workflow automation, document processing, business process automation I choose the technology based on the business requirement, scalability needs, budget, timeline, and long-term maintainability, not because one stack is trendy. Client feedback: “Aqeel and his team at Mi6 are highly professional. Their attention to detail is fantastic and their problem solving is second to none. I couldn't recommend them enough.” I prefer long-term partnerships where I can understand the business deeply If you are looking for a long-term technical partner who can understand your business, plan the right solution, and build reliable custom software, I would be happy to discuss your project. Send me a message with your idea, current challenge, or existing system, and I’ll help you think through the best next step.
