Gadget Guruz is India's pioneering on-site electronics repair and e-waste management platform based in Delhi NCR. We bridge the gap between independent technicians and customers via our Digital products (Website and Apps) and proprietary hardware solutions. Our mission is to bring quality, transparency and accountability to a largely unorganized industry.
Role Overview
As a Backend Developer, you will be a freelancer, on-site member of our Delhi NCR team, owning the design, implementation and maintenance of our core server-side systems. You'll work in a fast-paced, growth-stage startup environment--with blurred lines between Dev, Ops and Product--to build scalable, secure and high-performance APIs that power both web and mobile clients.

Implement caching (Redis/Memcached), queueing (RabbitMQ/SQS) and conduct load-testing
Cloud Infrastructure
Deploy, monitor and scale services on AWS (EC2, RDS, S3, Lambda, CloudWatch)
Define Infrastructure-as-Code with Terraform or CloudFormation
Quality & Security
Enforce web-security best practices (OWASP, input validation, encryption)
Own CI/CD pipelines (GitHub Actions/Jenkins), unit/integration tests (PHPUnit)
Collaboration & Mentorship
Partner with Frontend Html, CSS, Bootstrap and Mobile (Flutter) teams on API contracts
Must-Have Qualifications
3+ years of backend experience with Laravel and PHP (strong OOP & design-pattern skills)
Bachelor's degree in Computer Science, Software Engineering or a related field
Deep expertise in MySQL design, optimization and migrations
Proven track record building and securing RESTful APIs
Hands-on AWS experience (EC2, RDS, S3, Lambda) and IaC (Terraform/CloudFormation)

Preferred Skills
Containerization (Docker) and orchestration (Kubernetes)
NoSQL databases (MongoDB, DynamoDB)
Serverless architectures (AWS Lambda, API Gateway)

Competitive project contract based retainer
Flexible on-site/remote hybrid model (Delhi HQ)
