The kind of interfaces most designers find overwhelming. I find them interesting. Here's what I typically help with: 1️⃣ SaaS Dashboard & Web App Design Full UI/UX redesigns of data-heavy platforms, admin panels, multi-step workflows, and internal tools. Figma-based, developer-ready, built to scale. 2️⃣ UX Audit & Interface Redesign Deep-dive audit of what's broken - onboarding drop-offs, workflow friction, inconsistent patterns - delivered as a clear action plan your team can implement immediately. 3️⃣ Mobile & Web App Design End-to-end product design for web and mobile apps, from wireframes and user flows to high-fidelity prototypes and handoff. 4️⃣ Design Systems Custom or adapted design systems your dev team can actually use and maintain - not just a pretty Figma file nobody opens. 5️⃣ Website & Landing Page Design Corporate websites, product landing pages, and conversion-focused web design for startups and growing businesses. I work independently once briefed, take full ownership of the problem, and stay available as a long-term partner as the product grows. I'm not the right fit for every project - but if your product does something valuable and the interface is getting in the way, I probably am. Invite me to your project or send a direct message - let's talk. 🔸 UI/UX Design - UX Design - UI Design - Web Design - Mobile App Design 🔸 SaaS Design - Dashboard Design - Admin Panel Design - Internal Tool Design 🔸 Figma - Wireframing - Prototyping - User Flows - UX Audit 🔸 Product Design - App Design - Startup Design - B2B SaaS Design 🔸 Design System - Responsive Design - Developer Handoff - Accessibility 🔸 Website Design - Landing Page Design - Web App Design - Interface Redesign

I build and scale production SaaS and FinTech platforms using React, Next.js, Node.js and Python. Relevant FinTech experience: I contributed to Trastra, a multi-currency wallet and neobank product. My work included backend and mobile application development, KYC/AML onboarding, card issuing, Stripe Issuing, fraud detection and payout integrations. In a long-term engagement on a global commerce platform, I have worked on React/Node product functionality, performance optimisation, real-time content updates and authentication flows. I am most useful when a product needs one engineer who can connect business requirements with frontend delivery, backend APIs, data modelling and production deployment. What I can own: • React and Next.js application development • Node.js and Python services, APIs and integrations • Authentication, role-based access and payment flows • PostgreSQL / MongoDB data modelling and performance work • Docker, CI/CD and AWS-based delivery • Existing-product scaling, migrations and technical-debt reduction Core stack: React, Next.js, Node.js, TypeScript, JavaScript, Python, FastAPI, PostgreSQL, MongoDB, Docker, CI/CD and AWS. If you need to move an existing SaaS or FinTech product forward without splitting ownership across several freelancers, I can help from technical discovery through delivery and release.

I'm happy to start with a free consultation, quick POC, or a test task, your call. See the quality first, then decide. I build AI agents and automated workflows that take over the manual back-office work n8n and Make pipelines, LLM-powered agents, and the integrations that connect your CRM, inbox, Meta Platform, spreadsheets and databases so they stop needing a human in the middle. Head of Engineering at AB Ark. 10+ years shipping production systems, 3,495 hours and 100% Job Success on Upwork. WHAT I BUILD AI agents Multi-step agents with tool calling, retrieval and human-in-the-loop approval. Lead qualification and follow-up agents, document-processing agents, internal support agents that read your actual systems instead of a static FAQ. Built on LangChain, LangGraph, OpenAI and Claude. Workflow automation n8n, Make and Zapier self-hosted or cloud. Lead routing, invoice and document processing, report generation, ticket triage, timesheet and approval flows, data sync between systems that were never designed to talk to each other. Conversational automation WhatsApp Business API, Slack and web chat wired into real business systems, CRM lookups, order status, booking, escalation to a human at the right moment. System and API integration REST and GraphQL APIs, webhooks, OAuth, retries and idempotency. CRM and finance platforms including HubSpot, Kommo, SharpSpring and QuickBooks Online. Google Workspace, SQL and NoSQL data layers. RECENT WORK — Digital timesheet automation system: submission, approval routing and reporting, replacing a manual spreadsheet process — AI call-quality scoring pipeline: audio → transcription → LLM scoring against a rubric → dashboard — AI invoice monitoring dashboard (CostSaver): server-side rebuild and cost-anomaly alerting — Live weather data pipeline feeding a BI layer, fully automated ingestion STACK n8n · Make · Zapier · LangChain · LangGraph · OpenAI · Anthropic Claude · Python (FastAPI) · Node.js · React · Next.js · PostgreSQL · MySQL · MongoDB · Firebase · Redis · Docker · CI/CD · REST & GraphQL · WhatsApp Business API · Twilio HOW I WORK — I map the process before I automate it. Steps, systems, exceptions, and who currently does what. Automating a broken process just makes it fail faster. — Error handling and alerting are in scope by default, not phase two. An automation that fails silently is worse than no automation. — You own the workflows and the credentials. If it is n8n, I can hand it to you self-hosted and documented so you are not locked to me. — Milestones with written acceptance criteria, or hourly with daily updates. Send me the process you want automated, the steps, the systems involved, and where it currently breaks and I will map the workflow and give you an estimate. Best, Muhammad Zaman
