Umer SherazTechnical leaderAll-round full stack — mobile, web, backend, and cloud.

I ship products end-to-end — mobile apps, websites, and backend services — plus the cloud infrastructure, pipelines, and production operations that keep everything running.

  • Architecture, code review, and mentoring across squads
  • Production systems on AWS with Docker and Kubernetes
  • CI/CD, observability hooks, and pragmatic security

Clear architecture, kind code reviews, and shipping without drama.

That's the bar I hold for myself and the teams I support — whether we're launching an app, hardening an API, or automating the path to production.

Technical leader

Expertise

Skills & domains

Where I focus depends on the team and the risk — here is a honest map of the territories I cover.

01

Leadership & delivery

  • Set technical direction and keep the roadmap realistic
  • Work closely with product, design, and QA so everyone stays aligned
  • Help hire, mentor engineers, and agree on how we build software
  • Build a team culture where people own their work and can speak up
  • Ship on time without sacrificing quality, security, or cleanup of old code
  • Explain trade-offs, dates, and risks clearly to leaders and stakeholders
  • When things break: respond calmly, learn from it, and fix the root cause
  • Work with vendors and other teams when systems need to connect
02

Team & project management

  • Plan work from idea to release: lists, sprints, milestones, go-live
  • Track scope, risks, blockers, and who needs what from whom
  • See who is busy, what matters most, and spread work fairly
  • Share honest status: what is done, what is stuck, and what we decided
  • Use tools like Jira or Confluence when they help — not for show
03

Mobile

  • Android apps with Kotlin — UI, builds, and publishing to the Play Store
  • iPhone and iPad apps with Swift — building, testing, App Store releases
  • Flutter: one codebase for Android and iOS when that is the right fit
  • React Native: shared UI with native pieces when needed
  • Structure apps so they are easy to test, change, and grow
  • Push alerts, links that open the app, and data that stays safe on the device
  • Automated builds, app signing, and beta testing before users get the app
04

Backend & APIs

  • PHP with Laravel, CodeIgniter, and common PHP patterns
  • Node.js and NestJS for services and APIs that other apps call
  • Python with Django, FastAPI, or Flask
  • Design APIs, logins, and connections between systems in a clear way
05

Frontend

  • React and Next.js for modern websites and web apps
  • Vue.js for interactive user interfaces
  • TypeScript to keep larger frontends maintainable
  • Fast pages, usable for everyone, and layouts that work on phone and desktop
06

Cloud & AWS

  • Route 53: domain names, traffic routing, and health checks
  • S3: file storage, backups, permissions, and lifecycle rules
  • Elastic Beanstalk: deploy and update apps without hand-managing servers
  • Virtual servers (EC2), containers (ECS/EKS), and how they talk on the network
  • Databases (RDS), CDN (CloudFront), and who can do what (IAM)
  • Private networks (VPC), load balancers, APIs, and small serverless functions when useful
  • Secrets, config, logs, and alarms so you can see issues early
07

DevOps & platforms

  • Docker: package apps so they run the same everywhere
  • Kubernetes: run many containers reliably in production
  • CI/CD: automate test, build, and deploy (e.g. GitHub Actions, GitLab)
  • Linux servers: setup, updates, and basic hardening
08

AI & automation

  • Cursor — AI-assisted development for faster coding, refactors, and reviews in the IDE
  • Claude — pairing on architecture, specs, debugging, and clear technical writing
  • n8n and similar workflow tools — connect APIs, triggers, and services into AI automation pipelines
  • Practical AI workflows: repeatable prompts, agent-style tasks, and glue between product and ops tools
