It has been built as a modern TypeScript solution using a Node.js backend API with NestJS, a React administrative portal, and a Next.js customer-facing website. The product is hosted on a contemporary AWS cloud architecture using infrastructure as code via AWS CDK, with scalable services, managed data storage, content delivery, real-time capabilities and observability built in., As a Junior Software Developer, you will work as part of the internal development team to support ongoing development, bug fixes, testing, documentation and incremental enhancements across the API, web app and public website. You will be given structured support and guidance while building knowledge of the Gavel platform, our development practices and the wider auction business., * Deliver feature improvements, new features and bug fixes across the Gavel monorepo, including the Node.js/NestJS backend API, React admin portal and Next.js public website, with a focus on reliability, accessibility, performance and maintainability. * Maintain and evolve the backend API, developed using Node.js, NestJS and TypeORM, alongside the Aurora MySQL Serverless v2 schema and migrations; ensure data integrity, robust API design and query performance at scale. * Write clean, maintainable TypeScript code with guidance from senior developers, following agreed coding standards and review processes * Support the maintenance of backend services using NestJS, Node.js, TypeORM and Aurora MySQL, including safe changes to schemas, queries and migrations under supervision. * Contribute to front-end development using React and Next.js, helping improve usability, accessibility, performance and reliability. * Support testing activities, including unit, integration and end-to-end tests, and help investigate defects reported by users, operations or support teams. * Assist with integrations to third-party services by helping implement, test, document and troubleshoot API connections, webhooks and data flows. * Contribute to documentation, run-books and knowledge-transfer materials so that system knowledge is captured clearly for the internal team. * Learn and contribute to CI/CD pipelines, automated testing and infrastructure-as-code processes using tools such as GitLab CI, CodeBuild/CodeDeploy and AWS CDK. * Support operational monitoring and troubleshooting using CloudWatch dashboards, logs and alerts, escalating issues appropriately. * Apply secure development practices, including awareness of authentication, authorisation, data handling, secrets management, least privilege and auditable change control. * Apply AI Product Development Lifecycle (AI PDLC) best practices for future product development, using Claude Code to support structured requirements analysis, solution design, implementation, automated testing, code review, documentation and safe release planning. * Collaborate with Product, Operations, Support and other stakeholders to understand requirements, clarify issues and deliver incremental improvements safely. Technical Environment * Languages & frameworks: TypeScript, Node.js, NestJS, React, Next.js; monorepo via Lerna & Yarn workspaces. * Data & messaging: Aurora MySQL Serverless v2, RDS, TypeORM migrations, ElastiCache/Redis and Bull queues. * Search & real-time: OpenSearch; Socket.IO and AWS AppSync for live updates and bidding. * Storage & delivery: S3, CloudFront and image optimisation using Sharp/Lambda. * Authentication & security: AWS Cognito, Microsoft 365 federation, IAM, KMS, WAF and Secrets Manager. * CI/CD & infrastructure: GitLab CI, CodeBuild/CodeDeploy and AWS CDK using TypeScript. * Internal libraries: GCD Technologies Acorn modules, including assets, audit, authentication, CRUD, notifications, users and notes., * Environments: Production, Staging, UAT and Test; non-production environments are managed with cost-conscious configuration. * Delivery approach: iterative improvements, shared backlogs, code reviews, testing and controlled releases. * Observability: CloudWatch dashboards, logs and alerts, with escalation to senior colleagues where required. * Modern cloud hosting: the platform is deployed on current AWS managed services with infrastructure defined through AWS CDK, supporting scalability, secure release processes, resilient content delivery and cost-optimised non-production environments. * Security by design: secure development practices, VPC isolation, WAF, KMS encryption, Secrets Manager and audit trails. * Knowledge transfer: structured documentation, code reviews, pairing, run-books and clear handover materials to build internal capability. * AI PDLC going forward: future Gavel development will use Claude Code as part of a controlled AI-assisted engineering process, with human review, traceable decisions, automated testing, security checks and documentation embedded throughout the delivery lifecycle. ## Related Videos - [Rest API Antipatterns](https://www.wearedevelopers.com/videos/100208-rest-api-antipatterns) - [Reducing LLM Calls with Vector Search Patterns - Raphael De Lio (Redis)](https://www.wearedevelopers.com/videos/1714-reducing-llm-calls-with-vector-search-patterns-raphael-de-lio-redis) - [MySQL Protocol Features You Should Be Aware Of](https://www.wearedevelopers.com/videos/100267-mysql-protocol-features-you-should-be-aware-of) - [WeAreDevelopers LIVE – AI, Freelancing, Keeping Up with Tech and More](https://www.wearedevelopers.com/videos/1786-wearedevelopers-live-ai-freelancing-keeping-up-with-tech-and-more) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Coding for Good: Achieving social change with an app](https://www.wearedevelopers.com/videos/1645-coding-for-good-achieving-social-change-with-an-app) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [7 Most Popular Web Developer Jobs in Europe](https://www.wearedevelopers.com/magazine/163-7-most-popular-web-developer-jobs-in-europe)
