What I'm looking for

I’m open to high-impact international engineering roles and remote work worldwide, especially where AI integrations, measurable product impact, and production-ready systems across data-driven platforms matter.

I build production-grade full-stack web applications at Devsinc in Lahore, shipping end-to-end features across healthcare data integration, AI agent automation, and social/Web3 platforms.

On my AI Agent Automation Platform, I built a full-stack agent control panel from Figma through analytics dashboards and agent-insight modules. I also designed FastAPI services to route queries across ClickHouse, PostgreSQL, and MongoDB based on context, targeting lower per-endpoint latency.

I’ve integrated web3 wallet connectivity using Reown AppKit, including multi-wallet authentication, EIP-712 signing, and real-time on-chain status tracking. On the Medical Social Platform, I implemented Stripe Connect marketplace architecture, added OAuth 2.0 SSO (LinkedIn and Google), and migrated REST APIs to AWS Lambda to reduce infrastructure costs.

Before that, as an Associate Software Engineer, I contributed to a HIPAA-compliant microservices platform ingesting wearable and device data (Fitbit, Garmin, Oura, Dexcom, Omron). I upgraded Ruby and Rails across 5+ microservices and supported reliable CI via RSpec testing.
