I am a senior integrations expert specializing in: 1. Microsoft Graph API - any integration for the entire Microsoft 365 ecosystem. I build connections between Teams, Outlook, SharePoint, and OneDrive, automating document processing, calendar syncing and organizational workflows with external systems, applications and CRMs. 2. POS Systems & Specialized Software - development of POS systems like the Qulah - restaurant POS system, focusing on reliability, offline-first capabilities, and seamless user experiences. 3. Full Stack Developer - With over 10 years working with Laravel, Python and Nodejs, I ensure that frontend interfaces are intuitive while back-end architectures are secure, scalable, and maintainable. 4. Global Payments and API Integrations - I have extensive experience implementing complex payment gateways across diverse platforms, including Stripe, Paddle, Paystack, and M-Pesa. Clients work with me when they need more than just a developer; they need an architect who understands business needs and create applications their pain points. Whether it is building custom middleware, syncing CRM processes, or developing and deploying AI-powered workflows, I focus on delivering production ready solutions that bring value to my clients and their stakeholders. With over 10 years of experience (over 70 jobs, over 6000 hours and over USD 200,000 in earnings here on Upwork alone - which speaks of the trust my clients have with my delivery) in both small, medium and enterprise applications, I bridge the gap between complex business requirements and high performance technical solutions. Education wise, I hold an undergraduate degree in Computer Science and a Master’s in Information Systems, providing a deep academic and practical foundation for every project I undertake. Engage me anytime for your project and I look forward to bringing value to your business.

I help clients with Python-based API work, web scraping, automation, and data processing. Most of my work has involved: – Consuming and integrating APIs (Twitter/X, YouTube, third-party services) – Scraping and cleaning large datasets – Automating data pipelines and scripts – Building small web tools and dashboards I specialize in short-term, clearly scoped projects where you need something built, fixed, or automated without long onboarding. Tools I use regularly: – Python (requests, pandas, automation scripts) – APIs & webhooks – PostgreSQL / Google Sheets – React (for lightweight frontends when needed) I value clear communication, fast turnaround, and realistic scope. If your task fits that, I’m happy to take a look.

I’m a Full Stack Engineer specializing in AI integration for real-world applications. My work focuses on two key areas: upgrading existing software with intelligent AI-powered features, and building new AI-native products from the ground up. Whether you already have a working platform that needs automation and intelligence, or you’re launching a completely new product, I can handle the entire process end-to-end, from backend architecture and API integrations to frontend implementation and user experience. I specialize in integrating AI into business workflows in ways that are practical, scalable, and actually useful. This includes AI assistants, chatbots, automation systems, intelligent workflows, recommendation systems, and AI-powered operational tools. I also work extensively with APIs and third-party ecosystems such as WhatsApp, Instagram, Facebook (Meta APIs), payment systems, CRMs, and other external services to create connected, automated platforms. Beyond development, I work closely with clients to understand the actual business problem before jumping into implementation. In many cases, clients come in with one idea, but through discussion we identify a simpler, more scalable, or more cost-effective approach that delivers better long-term results. My goal is not just to write code, but to help build systems that make operational sense and create measurable value.
