Job Success
Karachi, Pakistan - 8:38 pm local time
Data entry, lead follow-up, report generation, document processing, CRM updates, every hour spent on that is an hour not spent growing the business. I build n8n automation systems that take that work off your plate permanently, not a workflow that breaks the moment your process changes.
Most automation consultants just connect tools. I combine software engineering with automation expertise to build solutions that fit how your business actually runs.
I help businesses cut repetitive work with AI, n8n, OCR, APIs, and custom integrations. I build systems that automate lead qualification, document processing, recruitment workflows, CRM operations, and reporting, anything that eats time your team could spend on real work.
I'm Sajjad Ali, a Full Stack Developer and AI Automation Specialist with 12+ years of experience building production systems for agencies, SaaS teams, and growth-focused businesses. Most automation freelancers know how to connect nodes in n8n. I combine that with real software engineering, so the systems I build handle edge cases, scale with your volume, and don't fall over when an API changes.
WHAT I BUILD:
→ Lead qualification & routing systems (form/CRM triggers → AI scoring → auto-routing to sales)
→ Document & OCR pipelines (PDF/DOCX extraction → AI parsing → structured data into your CRM)
→ Recruitment automation (CV intake → AI-powered candidate scoring → Sheets/Airtable/ATS sync)
→ CRM & reporting workflows (auto-updates, deduped records, scheduled reports, Slack/email alerts)
→ Custom API integrations connecting your CRM, ad platforms, payment systems, and internal tools
TECH I WORK WITH:
Automation & AI: n8n, OpenAI API, Gemini API, Ollama, webhook workflows, agentic AI systems
Backend: Node.js, NestJS, Express, Laravel, PHP
Frontend: Next.js, React, SvelteKit, Vue, Tailwind CSS
Databases: PostgreSQL, Supabase, MongoDB, MySQL
Integrations: REST APIs, CRM connectors (HubSpot, Pipedrive, Airtable), ad platform APIs, Slack, email automation, payment systems
BEST FIT IF:
✓ Your team is manually doing what a system should handle
✓ You're scaling client or lead volume without scaling headcount
✓ Your tools don't talk to each other and it's costing you time
✓ You need a technical partner who thinks in systems, not a ticket-taker
I respond fast, communicate in plain language, and build systems meant to run for years, not just pass a demo. If you're ready to automate operations, qualify leads faster, or finally connect your stack, let's talk.
