Full Stack Developer Role

Role Overview

As a Full Stack Developer at Mark 1, you'll bridge frontend flair with backend robustness, turning client requirements into deployable products. Your code directly impacts revenue-generating apps, like optimizing a client's checkout flow to cut cart abandonment by 25%.

Detailed Responsibilities

• Develop responsive UIs using React.js and Tailwind CSS for cross-device compatibility.
• Build RESTful APIs with Node.js and Express, integrating MongoDB or PostgreSQL databases.
• Implement authentication via JWT and OAuth for secure user sessions.
• Collaborate on CI/CD pipelines using Jenkins or GitHub Actions for seamless deployments.
• Debug and optimize code for performance, targeting under 2-second load times.
• Participate in sprint planning and retrospectives in Agile teams of 4-6 members.
• Contribute to documentation and client demos, explaining tech choices clearly.

Day-to-Day Workflow

Your day kicks off with a 10 AM stand-up via Slack or Zoom, reviewing overnight bugs and priorities. Mornings involve coding features, like wiring a new payment gateway, with pair-programming sessions for tricky logic. Afternoons shift to testing, pull requests, and client syncs, wrapping by 6 PM unless crunch time hits.

Expect 60% coding, 20% meetings, and 20% learning—perhaps a quick tutorial on Next.js optimizations. Hybrid Delhi office means 3 days in-person for whiteboarding sessions, fostering quick feedback loops.

Tools and Technologies

The stack leans modern: frontend with React, Vue.js, and TypeScript; backend via Node.js, Python/Django. Databases include MongoDB for flexibility and SQL for transactions. DevOps tools like Docker, Kubernetes, and Vercel handle deployments, with Figma for design handoffs.

Skills and Requirements

Technical Skills

Proficiency in JavaScript/ES6+, HTML5, and CSS3 is non-negotiable, alongside React or Angular experience. Know backend basics like Express.js, database queries, and API design. Bonus for Git, AWS basics, and understanding microservices architecture.

Soft Skills

Strong problem-solving shines in debugging under pressure, while clear communication ensures smooth client handovers. Teamwork thrives in daily scrums, and adaptability handles shifting priorities in fast-paced sprints.

Experience Expectations

For interns or juniors, a GitHub portfolio with 3+ full-stack projects trumps GPA—aim for deployed apps like a MERN todo list or e-commerce clone. No degree specified, but B.Tech CSE or equivalent preferred; show contributions to open-source or hackathons.
