About Zubair
AWS Solutions Architect | React & Node.js | AI Agent Engineer
Lahore, Pakistan - 11:08 am local time
I am a solutions architect and full-stack engineer 9 years in fintech,
payments and collections platforms. I design the architecture, then write
the code myself. Lately: AI agents that take real actions inside real
products updating records, resolving cases, editing content by
instruction not chatbots that just talk.
PROOF
→ Took deploy-safety coverage from 10% to 100% across 102 repos canary
releases, gated pipelines, auto-rollback. Bad code now dies in minutes,
not in front of clients.
→ Built the AI layer behind three production assistants (strategy, email,
landing-page editors), controllable by plain instruction with
permissioned "Act" tools so AI could safely update records, not just
describe what it would do.
→ Rebuilt a Snowflake/S3/QuickSight reporting pipeline: fixed silently
missing events, added PII masking across every downstream API. including
the AI tools, so client data stayed clean and clients stayed confident.
→ A client accidentally resolved 127 tasks with no way to undo it. I
built bulk task-recovery so it could never happen again, and that entire
category of support ticket disappeared.
→ Cut infra cost ~20% and helped pass an ISMS security audit on a 100+
microservice, cloud-native platform.
I do my best work with teams building something real, not prototypes
chasing the cheapest bid. Fintech and payments are my deepest reps, the
underlying skill, systems that don't fall over under real usage, travels
anywhere.
Tell me what you are building. I will tell you straight whether I am the
right fit.
Core stack: React, Node.js, TypeScript, Vue.js, GraphQL, AWS (Lambda,
Fargate, DynamoDB, CloudFormation, Bedrock, QuickSight), Microservices,
AI Agent Development, Snowflake, CI/CD.
