Abu Huraira · Senior Full-Stack Engineer

Senior Full-Stack Engineer · Sargodha, PK

I build the systems behind products that scale.

5+ years shipping AI-native platforms, SaaS automation, and backend infrastructure. I own products end-to-end — from system design and API architecture to deployment, observability, and the frontend that users actually see.

Selected Work

Products I've taken from idea to production.

Two platforms I architected, built, and operated as the sole or lead engineer. Real users. Real revenue. Real scale.

RevReply

AI-powered email reply automation for B2B sales teams. The platform reads incoming leads, drafts contextual replies with LLMs, and sends them through the customer's existing email provider.

What I built

Laravel monolith, Next.js dashboard, queue workers with Redis, MySQL data layer, and 20+ integrations including Gmail, Outlook, SendGrid, HubSpot, Slack, and Stripe.

How I scaled it

Horizon queues for async LLM calls, idempotent email sync, retry logic for provider rate limits, and monitoring with Sentry. Designed for multi-tenant isolation and reliable daily throughput.

Key decision

Kept the core product a focused monolith while using isolated workers for AI and email sync. This kept deployment simple but allowed horizontal scaling where it mattered.

JQJO

A 3-service AI news automation platform. Ingests news, translates it with LLMs, generates video, and publishes to 42 social accounts across 9 platforms — fully automated.

What I built

Python/FastAPI ingestion pipeline, PHP automation layer, Node.js publishing workers, FFmpeg media pipeline, and Cloudflare Stream for delivery.

How I scaled it

PM2-managed worker processes, scheduled queues, provider fallbacks for OpenAI/Gemini, and Ayrshare for social publishing. Built redundancy so a single API failure doesn't break the daily publish cycle.

Key decision

Split the pipeline into discrete services by job type (ingest, translate, publish) so each stage could be monitored, retried, and optimized independently without blocking the whole system.

Capabilities

How I work at a senior level.

I'm not just a code contributor. I make architectural decisions, manage production risk, and translate business goals into technical systems.

System Design

Design monoliths, services, and pipelines that fit the team size and traffic. I optimize for maintainability first, then scale.

AI Integration

Build reliable LLM workflows with prompt versioning, provider fallbacks, rate limiting, and human-in-the-loop guardrails.

Full-Stack Ownership

Own the backend, API, database, frontend, deployment, and monitoring. I ship complete products without waiting for handoffs.

Production Reliability

Queues, retries, observability, error tracking, and recovery paths. I design systems that degrade gracefully instead of crashing silently.

Let's build something serious.

I'm open to senior remote roles and on-site opportunities in the UAE, Saudi Arabia, and Qatar. If you need a senior engineer who can own a product and ship it to production, let's talk.
