Hey There! I'm Robert Deak 👋
Full-Stack Consultant Who Gets Things Done
Beyond just writing code, I solve real business problems. My track record includes helping companies save millions by taking machine learning models and turning them into actual products people can use, building intuitive interfaces that boost conversion rates and order completions, and consistently turned new features into successful deliveries.
When you need a developer who understands both technology and business outcomes, you need someone who creates solutions that move the needle—not just another resume full of tech stack buzzwords.
Frontend Expertise
Where User Experience Meets Engineering Excellence
React isn't just a framework to me - it's been my creative canvas for the past 6 years.
React Architecture That Scales
I've built everything from simple components to complex enterprise applications serving thousands of users. I've created dynamic data exploration platforms that make complex datasets feel intuitive, and built multi-step forms with very complex field dependencies.
Performance Optimization Obsession
Remember those 5-second load times that were driving your users crazy? I've turned those into 300-millisecond experiences. It's not magic - it's methodical optimization and knowing exactly where to look.
Design-to-Code Translation
Give me a Figma design, and I'll deliver pixel-perfect, responsive components that work beautifully across devices. I've transformed dozens of designs into production-ready React applications.
The Consultant Advantage
I don't just write React code. I help your team establish patterns, implement testing strategies, and create component libraries that your entire engineering organization can build upon.
Backend Development
Building the Engine That Powers Everything
API Design That Developers Love
I craft RESTful and GraphQL APIs that are intuitive, well-documented, and built to handle whatever you throw at them. Redis caching, optimized database queries, error handling that actually helps.
Database Whisperer
15+ years with SQL means I can make your Oracle, PostgreSQL, or MongoDB sing. I've optimized queries that reduced response times from 5+ seconds to under 300ms.
System Integration
Need to connect disparate systems? I've integrated everything from Stripe and Xero to complex pharmaceutical data sources. I speak the language of APIs.
The Problem-Solver Mindset
When I encounter a gnarly backend challenge, I don't just patch it - I dig deep to understand the root cause. Whether it's migrating legacy PL/SQL to modern Node.js services or designing fault-tolerant systems, I'm the consultant who stays until it's done right.
Data Engineering
Turning Information Into Intelligence
OLAP Systems & Analytics
I've built employee training tracking systems and workforce allocation platforms that provide real-time insights. Your executives need dashboards that tell a story - I create them.
ETL Pipelines That Just Work
Whether you're processing massive datasets or streaming real-time information, I design data architectures that are both robust and maintainable.
Search & Discovery
Engineered a federated search engine with custom relevance scoring that delivers more accurate results across multiple data sources. Your users shouldn't need a PhD to find what they're looking for.
The Curious Consultant
I don't just implement your data requirements - I ask the questions that help you discover what you really need. Being naturally social helps me connect with stakeholders across all levels of your organization, turning complex technical challenges into clearly defined problems that everyone can understand and rally behind.
What decisions are you trying to make?
What insights are hiding in your data?
How can we make this data actionable?
DevOps & Infrastructure
Making Deployment Day Feel Like Any Other Day
Infrastructure as Code
Terraform, AWS provisioning, repeatable environments - I automate the boring stuff so your team can focus on building features.
CI/CD Pipelines That Actually Work
GitHub Actions, automated testing, seamless deployments - I build pipelines that catch problems before they reach production.
Monitoring & Performance
AWS Lambda, API Gateway, DynamoDB - I design cloud-native architectures that scale automatically and fail gracefully.
The Get-Things-Done Attitude
DevOps isn't just about tools - it's about culture. I help teams adopt practices that make everyone more productive. Because when deployment is easy, innovation accelerates.
Your 3 AM wake-up calls should become a thing of the past.
Real Problems, Real Solutions
Here's how I've helped companies tackle complex technical challenges and deliver measurable business value.
We need a collaborative platform where teams can share and discuss ideas for new business products. The platform must handle dynamic business entities with multiple, varying relationship types between them.
The Solution
I implemented a graph database to model entities and their complex relationships. I built a GraphQL API layer to provide flexible data access and created an interactive force-directed graph visualization that enables users to create nodes, edit their own contributions, and engage through comments and likes.
Tools & Technologies
Our API aggregates data from multiple databases before returning responses, resulting in response times that fail to meet SLA requirements.
The Solution
I profiled API endpoints using APM tools to identify bottlenecks and analyzed slow database queries to optimize indexes based on query patterns. When database-level optimization wasn't feasible, I implemented a Redis caching layer with lazy loading strategy to significantly reduce response times.
Tools & Technologies
As a business analyst, I need an OLAP solution to organize and analyze large data volumes for various business intelligence needs across the organization.
The Solution
I built an ETL pipeline to centralize data in Elasticsearch and designed index templates with properly mapped data types for each source system. I deployed Kibana dashboards for standard analytics and developed custom visualization dashboards for specific business requirements.
Tools & Technologies
We need to productionize an ML model currently developed in Jupyter notebooks and integrate it with our core business API.
The Solution
I orchestrated the ML workflow using Airflow DAGs to separate data ingestion, model training, validation, and deployment stages. I packaged the trained model as a pickle file and served it through a FastAPI microservice that integrates with the existing API infrastructure.
Tools & Technologies
Our enterprise application serves thousands of customers, but lacks consistency in UI/UX across different modules, creating a fragmented user experience.
The Solution
I developed a design system and component library that provides reusable UI building blocks. I ensured all application features are built using these standardized components to maintain consistent look, feel, and behavior throughout the platform.
