Job Success
Karachi, Pakistan - 8:34 am local time
7+ years building with TypeScript across React, Angular, Node, and Firebase. A big part of my work now is AI integration: connecting GPT, Claude, and Gemini into real workflows, building agents that handle repetitive tasks, and automating the slow parts of your operations so your team can spend time elsewhere.
What I can help with:
- Full builds, front end to back end, including DevOps and deployment
- AI integration and custom agents (OpenAI, Claude, Gemini, AWS Bedrock)
- Workflow automation and CRM setup (Zoho, HubSpot, Salesforce, GoHighLevel)
- Payment and data integrations (Stripe, Plaid, PayPal, Google Maps)
- Maintaining, fixing, and extending apps you already have
I keep communication clear and steady throughout. You'll always know where the project stands, and you won't have to chase me for updates.
My stack:
Front end: React, Next, Angular, NgRx, Redux, Vue
Back end: Node, Express, Nest, GraphQL, REST, Lambda, Cloud Functions, Firebase
Databases: MySQL, MSSQL, Postgres, MongoDB, Firestore, Supabase
Cloud and DevOps: AWS (EC2, S3, Beanstalk, Route 53, Bedrock), GCP, Azure, Docker, CI/CD
Testing: Jest, Jasmine
Tools: GitHub, GitLab, Bitbucket, Jira, Trello, Asana, ClickUp, Monday
