Employment

Fitter Health

Software Engineer, Full-stack and Cloud · Contract
2026Remote · Spain-based team
  • Took a validated health-tech concept from zero to a live product used by patients and providers. Designed and built the frontend, backend, database, cloud infrastructure, and data layer, then documented and handed over the system.
  • Shipped the AWS estate across ECS, RDS, S3, SNS, SQS, IAM, and VPC with containerisation, least-privilege access, and multi-availability-zone deployment.
  • Defined API contracts and backend workflows; built notification and file-handling architecture on Celery and Redis, backed by 135 passing tests, reversible migrations, and database-level integrity constraints.
  • Modelled membership and entitlement workflows across a 106-table PostgreSQL schema covering credit balances, session booking, e-commerce, admin CRM, and invoice status synchronisation with Odoo.
  • Designed an ETL pipeline into a star-schema PostgreSQL warehouse for data-science workflows, product analytics, and partner reporting.
  • Automated member lifecycle email with EventBridge-scheduled Lambda and SES, including renewal reminders and inactivity re-engagement.
  • Diagnosed silent notification loss and added SQS between SNS and consumers so failed delivery became retryable with a dead-letter path.

Expertflow

Software Engineer, Backend and Cloud
2024 – 2026Lahore · Cisco UCCE solution partner
  • Owned backend REST APIs serving 1,000–3,000 daily users, deployed as Docker containers on AWS EC2 behind an Application Load Balancer with rate limiting, scoped IAM, and VPC isolation.
  • Re-deployed the backend as a distributed system on AWS EKS with Horizontal Pod Autoscaler policies that scale replicas with request throughput.
  • Reduced admin panel response time from 130 ms to 30 ms through Redis caching and database-index tuning after profiling identified query cost.
  • Designed and shipped event-driven batch and streaming ETL pipelines using AWS Lambda, MWAA, EMR, PySpark, Glue, and S3, producing analytics-ready Parquet for BI and ML workflows.
  • Developed a real-time voice and video communication SDK on WebRTC and the REST APIs connecting frontend clients, SDK modules, and third-party platforms.
  • Implemented a chatbot workflow, SQL-based customer-insight analytics, and time-bound permission controls.
  • Worked across Angular frontend, backend, and SDK teams to deliver features end to end.
