Independent React & Next.js Developer
Get your development backlog moving.
I help development agencies and SaaS teams fix React and Next.js issues, improve existing applications, and integrate APIs without a full-time hire.

Investment
Packages
Choose a Fix Sprint, Development Sprint or Monthly Development Support. All pricing is in USD; scope, deliverables and payment terms are agreed before work starts.
Fix Sprint
A focused engagement for a clearly scoped application issue. If the cause is unclear, I will propose a separately priced investigation before quoting implementation.
- One agreed issue or a small set of related fixes
- Scope and acceptance criteria agreed before work starts
- Code changes delivered through a pull request or agreed handover
- Testing notes and a short handover summary
- Typical delivery in 3-5 business days after scope, access and initial payment are confirmed
- 50% upfront, 50% on completion of the agreed deliverables
- Additional work requires a separate estimate and approval
Development Sprint
A defined frontend feature, API integration or larger backlog task for agencies and SaaS teams, with agreed deliverables and milestones.
- Defined frontend feature, integration or backlog task
- Deliverables and acceptance criteria agreed in advance
- Your repository and pull request review workflow
- Milestones, schedule and payment terms set in the proposal
- Relevant testing and documented handover
Monthly Development Support
An agreed allocation of hours for recurring fixes, improvements and maintenance after an initial engagement.
- Agreed monthly hours and prioritized tasks
- Scheduled fixes, improvements and maintenance
- Summary of completed work and remaining priorities
- Response windows agreed in writing; no default on-call coverage
- Additional hours require a separate estimate and approval
