Muhammad Zeeshan Jawed, also known as Zeeshan Jawed, Zeeshan Javed, Zeeshan Jawaid and Zeeshan, is a Full Stack Engineer from Karachi Pakistan. He specializes in Node.js, Angular, TypeScript, analytics and data visualization, MongoDB, PostgreSQL, Redis, AWS, OpenAI API integrations, REST APIs and scalable SaaS systems.
Across a Techstars-backed social-media platform I own the Angular app, the Node.js backend, the 10+ microservices behind it, and the AI and agent tooling on top — for 30,000+ users.
Most of what I build runs database-to-UI: features, the analytics behind them, and the performance work that keeps it fast.
Over 3.5 years I've shipped across the entire product — publishing, engagement, analytics, social listening, team workflows, calendar, and audience targeting — and the fleet of Node.js microservices behind it: publishing, analytics, engagement, video & media workers, auth, and AWS Lambda.
Lately that's meant a lot of AI and agent tooling too — an MCP server surface so assistants can publish, an OpenAI-powered content wizard, and a published n8n node for automation platforms.
So I'm comfortable everywhere — an Angular dashboard one day, a queue-based worker with retries and token handling the next. I like systems simple enough to reason about and tough enough to survive real traffic.
"Bug-Solving Maestro" — recognized two years running, 2024 and 2025.
An MCP tool surface, an OpenAI-powered content wizard, and a published n8n community node.
Social platforms integrated and hardened — Meta, LinkedIn, TikTok, YouTube, Threads, Mastodon, Bluesky.
What I use to ship full-stack features, analytics, and integrations for SaaS at scale.
Analytics, integrations, and full-stack features for SaaS and enterprise platforms.
A few projects that show how I work — end-to-end, data-heavy, and shipped.
An end-to-end analytics product — interactive charts, demographic breakdowns, world-map visualizations, and exportable PDF reports — that turned basic stats into real insight for 30,000+ users. Built across Angular (with D3) and a Node.js / MongoDB backend.
Tool surfaces that let AI assistants and automation platforms drive the product directly: MCP tools for publishing, scheduling and channel management with role-scoped access, plus a published n8n community node for channels and post creation — tested for scheduling, retries and idempotency.
Owned end-to-end: multiple report schedules per alert, personalized branded PDF report emails with computed summary cards, a cron delivery sweep, and a flag-gated staged rollout.
Contributed across 10+ Node.js services — publishing, analytics, engagement, video & media workers, auth, and AWS Lambda — with queue-based jobs, retries, and token handling.
Built and hardened integrations across Facebook (feed_targeting/audience), LinkedIn, TikTok, Instagram, YouTube, Threads, Mastodon and Bluesky — making unreliable third-party APIs behave in production.
Integrated the OpenAI API into the publishing flow so users could generate post captions in-app — wired up reliably with caching and graceful fallbacks.
A tamper-proof, blockchain-based system for verifying university degrees — built after mapping KU's real manual process. Validated years later when HEC Pakistan launched a similar on-chain attestation system.
REST APIs and data models for a ride-hailing app's core booking flows, plus a full-stack ERP platform built end-to-end from Node.js APIs to React modules.
Where the fundamentals came from, and what they've added up to.
Backend engineering, analytics, AI integrations, and scalable SaaS architecture.
How Retrieval-Augmented Generation works, and how to build RAG apps with embeddings, vector databases and LLMs.
