Dear Hiring Manager,

I ship products that hold up under real users — tight React front-ends, well-modelled APIs, and the cloud plumbing that keeps both upright.

I am writing to apply for the full-stack position at [Company Name]. Over the last five years I have delivered production web systems end-to-end: a Next.js storefront with a Django API and PostgreSQL backend, containerised and shipped to AWS behind a GitHub Actions pipeline; React and Vue dashboards over REST and GraphQL APIs; Node.js services integrated with MQTT for live telemetry; and a portfolio of 30+ open repositories that doubles as a public record of how I work. I have been formally verified by HackerRank on Problem Solving, Python, SQL, REST APIs, and CSS, and I keep the BNSP IoT Practitioner certification current, which often translates to better instincts on the device-edge side of the stack.

My day-to-day defaults: TypeScript on the front-end (React, Next.js, Tailwind), Python or Node.js on the back-end (Django, Flask, Express), PostgreSQL or MySQL for relational data and Redis for cache and queues. I write GraphQL where the schema benefits from it and REST where it does not. Authentication is done properly — JWT or session with refresh, RBAC, and rate limiting. I am comfortable owning the whole CI/CD loop: Docker, GitHub Actions, Jenkins, blue-green or canary deploys, infrastructure as code with Terraform, and Kubernetes manifests for anything that needs to scale. I do not treat observability as a finishing touch — logs, metrics, and traces are part of the first PR.

Highlights of fit for this role:
  • 5+ years shipping production web systems with React, Next.js, Node.js, Django, Flask, and GraphQL/REST APIs.
  • Strong data-modelling and SQL fundamentals; verified by HackerRank SQL Intermediate and problem-solving badges.
  • Cloud-native delivery: Docker, Kubernetes, Terraform, GitHub Actions, AWS, GCP, and Firebase in production use.
  • Live-portfolio record: 30+ open repositories, including live sites reviewed by the same CI pipeline your team likely uses.
  • Multilingual remote collaborator (English, Indonesian, Arabic, Javanese) with five years of async-first delivery across time zones.

Working remotely from Indonesia since 2018, I default to written-first updates, small reviewable pull requests, and short planning documents over long meetings. I am used to slotting into a team that already has a senior engineer and a product owner, taking ownership of features end-to-end, and being honest about scope. My rate is USD 35/hour with a USD 250 project minimum, negotiable on scope, duration, and retainer shape; I am equally happy on a one-month build-out and a six-month embedding with your platform team.

I would welcome a conversation about your stack, the team I would be joining, and the next thing you are trying to ship. You can reach me at azzar.mr.zs@gmail.com or +62 822 3252 9804, and the full project archive is at 1999azzar.github.io/1999AZZAR. Thank you for reading — I look forward to hearing from you.

Sincerely,
Azzar Budiyanto
