How We Work

The Development Lifecycle

Discovery & Arch

Deep dive into your business logic, defining data models, API contracts, and selecting the optimal tech stack for your specific requirements.

Prototyping & UX

Translating wireframes into interactive prototypes. Ensuring the user journey is frictionless before a single line of backend code is written.

Agile Development

Iterative, sprint-based coding. You receive weekly staging environment updates, allowing for continuous feedback and course correction.

Launch & Scale

Rigorous QA testing, CI/CD pipeline setup, and deploying to cloud infrastructure (AWS/Vercel) ready to handle production traffic.

Client Feedback

Word on the Street

"Leo didn't just build an app; he re-architected our entire backend logic. His deep understanding of Node.js scaling saved us months of future technical debt. Absolute professional."

Sarah Jenkins

CTO, FinServe Analytics

"Finding a full-stack dev who actually understands UX design is rare. Leo delivered a headless CMS solution that is incredibly fast and intuitive for our marketing team to use."

Marcus Thorne

VP Product, RetailTech

"Communication was flawless throughout the 6-month project. He managed the AWS migration seamlessly with zero downtime for our active SaaS users. Highly recommended."

Common Questions

For custom web applications, a typical MVP phase takes between 6 to 10 weeks. This includes discovery, design, development, and QA. More complex legacy migrations can take 3-6 months. I prioritize transparent, weekly milestone updates.

I specialize in JavaScript/TypeScript ecosystems. My go-to modern stack is React/Next.js for the frontend, Node.js or Python for the backend, supported by PostgreSQL and managed cloud services like AWS or Vercel.

Absolutely. Every major project comes with a 30-day bug-fix guarantee. Beyond that, I offer ongoing retainer contracts for maintenance, server monitoring, and feature iteration based on user feedback.

I operate primarily on value-based, fixed-price contracts for well-defined scopes to ensure you know exactly what you are paying. For ongoing or highly experimental R&D work, I offer weekly sprint billing.
