Businesses often outgrow spreadsheets, disconnected tools and off-the-shelf software that no longer fits how they operate. I design and build custom, database-driven business systems that bring processes, users and information together in one reliable platform. I work as a long-term technical partner for organizations that need complete, end-to-end solutions, including: • Custom CRM and ERP systems • Customer, member, employee and vendor portals • SaaS and multi-tenant web platforms • Internal operations and workflow systems • Database design and administration tools • Reporting dashboards and management visibility • API integrations and data synchronization • Legacy-system modernization and data migration As a Top Rated Plus Upwork professional with $300K+ earned and 6,900+ hours, I combine full-stack development, systems analysis and technical project leadership. I can take a project from initial discovery and process mapping through architecture, database design, development, testing, deployment and ongoing improvement. My experience includes building and supporting membership systems, admissions and learning platforms, expense-management workflows, operational dashboards, administrative portals, marketplace platforms and API-connected business applications. My approach is practical and structured: 1. Understand the business process and existing pain points 2. Define users, roles, workflows, data and reporting requirements 3. Design a maintainable system and database architecture 4. Deliver the solution incrementally with regular demonstrations 5. Manage testing, deployment, documentation and user adoption 6. Continue supporting and improving the platform as the business grows Core technologies include C#/.NET, ASP.NET, PHP, JavaScript, SQL Server, MySQL, REST APIs, HTML/CSS, Power Platform and modern web-development frameworks. Automation and AI can be incorporated where they deliver genuine business value, but the foundation is always a secure, maintainable and usable business system. I am best suited to clients looking for more than a short coding assignment—especially organizations seeking a dependable technical partner who can understand their operations, own delivery and support the system over the long term. Let's discuss your project and get the ball rolling, Zain H.

I'll tell you honestly whether I'm the right fit and exactly how I'd approach it.

HI! I’ve built 40+ AI agents and automation systems handling thousands of tasks daily from lead processing to full operational workflows. Most clients come with something that “almost works”. Flows break. Data is messy. No one understands what happens inside. I fix that. I design automation with clear logic, clean data flow, and control at every step. If something fails it retries. If data is wrong — it is blocked. If system grows — it still works. What I usually build: – AI agents for operations and sales – n8n / Make workflows with real error handling – CRM and API integrations – data pipelines and internal toolsWhat I build: – Supabase and PostgreSQL backends with clear schema – Internal tools with lovable and supabase – Data pipelines from scraping to AI to CRM I use AI to move faster. But I always check logic and edge cases manually. Experience: 40+ AI agents and automation systems RAG systems with vector search and clean outputs CRM and sales automation pipelines internal tools with supabase and APIs systems built for real load If your automation is messy I can rebuild it. If you start from zero I can design it right. 🔧 Stack: n8n | make | supabase | postgresql | lovable | openai | rag | apis | webhooks | crm systems | data pipelines | ai agents
