About Krishnaraj

Full Stack Developer helping businesses build web & mobile apps that actually work.

7+ years building for banks, fintech, and mobility companies. I work with React, React Native, TypeScript, and Python — and I bring AI into the mix when it makes sense (smart features, automation, document processing).

Right now I lead frontend architecture for a major UAE bank's digital platform, so I know how to build things that are fast, secure, and production-ready — not just demos.

What I can build for you:
  • Web apps (React/Next.js)
  • Mobile apps (iOS + Android, one codebase)
  • AI-powered features
  • APIs and backend systems
  • Cloud deployment (AWS)

I keep things simple, communicate clearly, and ship code you can actually launch.

Experience

  • Abu Dhabi Commercial Bank (ADCB), via Talent Arabia Technologies
    Senior Full-Stack Web Developer & Tech Lead
    DIGITAL AND IT
    March 2025 - July 2026 (1 year and 4 months)
    Abu Dhabi - United Arab Emirates
    • ● Lead full-stack architecture and delivery for ADCB's unified digital onboarding platform — React front-end, Node.js/Python services, containerized on Kubernetes — replacing a legacy monolith with a modular micro-frontend system spanning Cards, CASA, and Loans product lines.
    • ● Own the AWS CI/CD pipeline end-to-end: authored and maintain GitHub Actions workflows and AWS CodeBuild build specs across three modular repos, with automated build, test, CodeQL security scan, and containerized deployment stages to Amazon EKS via ECR.
    • ● Manage Kubernetes deployments on EKS — resolved pod-scheduling ceilings, TLS certificate rotation, cross namespace service resolution, and NGINX ingress routing issues to keep the pipeline reliable in production.
    • ● Configured IAM roles and IRSA (IAM Roles for Service Accounts) for secure, least-privilege AWS S3 access from in cluster services; set up CloudFront distribution for static asset delivery.
    • ● Designed and built a self-hosted document-intelligence service (Python/FastAPI + PaddleOCR) that replaced a paid third-party OCR vendor, cutting licensing cost and keeping data in-house.
    • ● Guide task breakdown, design review, and delivery tracking across the onboarding workstream, coordinating directly with backend, QA, and product teams to keep releases predictable.
    • ● Diagnosed and resolved production authentication failures (OAuth token-failure cascades), hardening platform reliability under regulated-bank constraints.

    • ● Led cross-platform React and React Native development for fintech and healthtech clients, working directly with designers and product owners to translate specs into production UI.
    • ● Architected state for complex multi-step user flows (Redux Toolkit, Zustand); delivered real-time features via WebSockets and polling.
    • ● Drove team-wide adoption of TypeScript and automated testing (Jest, React Testing Library); mentored junior developers on code quality and delivery practices.
