End-to-end data platform for a leading online classifieds group (4 marketplaces): 59 PySpark ETL jobs on AWS Glue batch-loading ~3.7M rows/day into a ~1.9-billion-row Amazon Redshift warehouse, with staging/MERGE patterns, deduplication, and data-quality checks throughout. Run telemetry is built into the warehouse itself — 99.6% fleet success rate across 25K+ runs in the trailing 90 days.

Title: Enterprise ATS & Hiring Requisition Platform
Description:
An applicant tracking system built for enterprise recruitment teams who had hiring data scattered across spreadsheets, inboxes and three different tools — with no single view of what was actually happening.
The core of it is the admin dashboard: a company-wide pipeline funnel from application through screening, interview, offer and hire, with velocity metrics on each stage so leadership can see where candidates stall rather than just how many are in the system. Alongside it sits recruiter performance comparison, job health monitoring and a hiring calendar.
Beyond the dashboard, the platform handles resume parsing and candidate search, job posting and interview scheduling, client and vendor management, and invoicing. I built an asynchronous Gmail and Outlook inbox sync on AWS SQS with a dedicated worker process, so recruiter email threads attach to the right candidate record automatically instead of being copy-pasted in.
The piece I'm proudest of is the hiring requisition module. An employee raises a hiring request, it routes up the reporting hierarchy for approval, branches depending on whether the role is budgeted or unbudgeted, and on final sign-off creates the job in the ATS automatically for HR to hire against. It's designed for roughly 600-person org hierarchies, which meant getting the approval routing right mattered more than any individual feature.

What if AWS infrastructure could detect problems before they become incidents?
I recently built an AI-powered AWS SRE automation system designed to reduce repetitive infrastructure operations.
The system:-
- Monitors EC2 CPU patterns using CloudWatch
- Uses AWS Bedrock to analyze infrastructure patterns
- Generates scaling recommendations
- Sends recommendations for human approval
- Automates the approved EC2 resize workflow
- Generates automated vulnerability insights using AWS Inspector
The goal wasn't to replace engineers it was to reduce repetitive investigation and help engineers make infrastructure decisions faster.
This is the kind of AWS automation I enjoy building: practical systems that reduce operational overhead while keeping humans in control
Open to new work — full-time or contract.
I'm a full-stack engineer with 6+ years of experience, working with TypeScript across the stack. Most of that time has been spent embedded in a small number of products for years at a time, rather than rotating between short gigs — which means I've owned things long enough to live with my own decisions.
What I build:
AI/LLM products — tool-calling agent workflows that act on results autonomously, retrieval-grounded generation over large corpora, structured outputs with validation, and evaluation against real outcomes. Built in-house, with the model provider behind a service boundary so routing stays swappable.
Payments — Stripe Connect and Subscriptions in production: recurring billing, plan changes, usage-based charges, marketplace payouts, and webhook-driven reconciliation so the ledger stays accurate when events arrive late, twice, or out of order.
Integrations — 15+ third-party APIs including Amazon Seller/Vendor Central, Google, and Microsoft Graph behind one normalized interface, cutting integration time by ~40%.
Real-time & scale — WebSocket services maintaining consistent state for thousands of concurrent users, with reconnection and out-of-order delivery handled explicitly.
Stack: TypeScript · React · Next.js · Node/Express · PostgreSQL · Redis · AWS · Docker · CI/CD. Claude Code and MCP tooling are part of my daily workflow.
If you're shipping something early-stage and need someone who can take a feature from schema to production without a handoff, my DMs are open.
good luck in your job search Ali
