Server‑Side Language/Runtime: Expertise in a language commonly used for web applications:
Node.js (Express)
Python
PHP (WordPress, Laravel methodologies)
Database Systems: Strong command of both relational and non‑relational databases:
SQL Databases (e.g., PostgreSQL, MySQL): Advanced querying, optimization, and database design (schemas, indexing, normalization).
NoSQL Databases (e.g., MongoDB, Redis): Understanding when to use them, data modeling, and performance tuning.
API Development: Mastery of designing and building efficient, secure APIs:
RESTful APIs: Design principles, best practices, and versioning.
GraphQL: Deep knowledge of query language, schema design, and resolvers.
Architecture & Infrastructure
Version Control: Complete mastery of Git and platforms like GitHub/GitLab/Bitbucket.
Cloud Platforms: Familiarity with major cloud service providers (e.g., AWS, Azure, GCP) and core services like compute, storage, and networking.
Hosting Infrastructure support – WPEngine, DigitalOcean, Netlify – familiar with many hosting methodologies, shared, virtual, baremetal, etc., and website host migrations.
Understanding of SSH & SFTP/FTP functions and setting up accounts and servers in a variety of shared and virtual private hosting environments.
Understanding of domain and hosting functions to create, transfer and troubleshoot client assets between hosting environments and providers.
Knowledge of setting up/importing/exporting databases for CMS setups and transfers:
Via plugins/GUI tools at a minimum, via CLI tools a major plus.
DevOps & Deployment: Understanding of continuous integration/continuous deployment (CI/CD), and containerization technologies like Docker and Kubernetes.
Architectural Patterns: Ability to implement and reason about patterns like Microservices, Serverless (e.g., AWS Lambda), Monoliths, and Headless CMS (e.g., Contentful).
Full‑Stack Frameworks: Knowledge of meta‑frameworks that combine front‑end and back‑end logic, such as Next.js or Nuxt.
CMS – WordPress, Concrete CMS, Shopify and familiarity with various other CMS solutions such as Decap, Craft, BigCommerce.
Experience with static site generators such as Eleventy or Jekyll.
Experience supporting QA test automation.
Developing accessible (WCAG 2.0 - 2.2 standards, A & AA level compliance) websites.
Performance & Security
Web Performance Optimization (WPO): Techniques for optimizing site speed, including bundle size analysis, code splitting, caching strategies, and meeting Core Web Vitals.
Security Best Practices: Knowledge of common vulnerabilities and mitigation techniques (OWASP Top 10), including cross‑site scripting (XSS), SQL injection, secure authentication/authorization (OAuth, JWT), and secure header configuration (CSP).
Preferred Soft Skills
Exceptional written and verbal communication skills, with the ability to explain complex technical concepts to non‑technical stakeholders.
Strong analytical and problem‑solving abilities, with a proven track record of resolving critical issues.
Proven leadership and project coordination experience.
A passion for continuous learning and staying current with emerging web technologies and industry trends, including coding with AI.
