Delivery principles

Senior technical judgement
Technical recommendations are scoped to business value, operational risk and maintainability.
Maintainable code
Implementation is structured, documented and prepared for future handoff.
Clear communication
Status, constraints and trade-offs are communicated throughout the engagement.
Existing systems
Work is planned around the current stack unless a replacement is technically justified.
Incremental delivery
Changes are released in controlled steps with rollback paths where appropriate.
White-label collaboration
Delivery can operate behind the agency brand and within existing client communication models.

Initial engagement: a complimentary three-finding WCAG review of one client site, including the findings, the corrective actions and their priority.

How I work

Delivery process

A defined process from problem definition to production.

  1. Define

    The business goal, technical constraints and completion criteria are established before implementation begins.

  2. Diagnose

    The codebase, data model, infrastructure and user flows are reviewed to identify root causes.

  3. Plan

    Technical decisions, sequencing, dependencies and trade-offs are documented before build work starts.

  4. Build

    Implementation is delivered incrementally, with changes kept reviewable and documented.

  5. Test

    Quality assurance includes functional checks, accessibility review and performance validation where relevant.

  6. Deploy

    Production releases follow controlled steps, with rollback options where the environment supports them.

  7. Handoff

    Documentation, operational notes and ownership details are prepared so the system can be maintained.

Profile

About

I am a senior full stack developer based in Argentina, working remotely with agencies and product teams across different markets. I have worked in professional web development since 2018, building on an earlier background in IT, hardware, electronics, networking and systems support going back to 2008.

I work end to end —backend, frontend and infrastructure— with a focus on software engineering, architecture decisions and technical consulting, prioritising clear assessment, maintainable implementation, documentation and handoff. I join existing teams or own complete projects.

Accessibility remediation and performance engineering are strong specialisations within that scope: WCAG/ADA work, Core Web Vitals and 500+ sites audited or remediated for accessibility since 2021.

I am also the founder of AccessAuditLab, a specialised initiative in digital accessibility, technical audits and WCAG remediation. Visit AccessAuditLab

FAQ

Practical questions before contact

Short answers for agencies, recruiters, product teams and technical leads evaluating fit.

Do you work with agencies under white label?

Yes. I can work behind the scenes inside an existing agency workflow, including tickets, Git, staging, QA, estimates, implementation notes and client-confidential delivery.

Do you only work with WordPress?

No. WordPress and WooCommerce are part of the stack, but the main positioning is full stack web engineering across PHP, Laravel, React, APIs, infrastructure, performance and accessibility.

Can you join an existing team or codebase?

Yes. Much of the work is on existing systems: production sites, legacy platforms, ecommerce stores, Laravel apps, API integrations and maintenance or rescue projects. I also own complete projects end to end.

Do you provide WCAG/ADA remediation?

Yes. The process combines automated testing, keyboard review, semantic review, code-level remediation, retesting and screen-reader checks when appropriate. I do not make legal compliance guarantees.

What kinds of projects are a good fit?

Accessibility remediation, Core Web Vitals work, Laravel/React platforms, WooCommerce improvements, API integrations, AI/RAG automation, technical rescue work and ongoing senior development capacity.

Are you available for full-time roles or only projects?

Both. I work remotely from Argentina with agencies, product teams and international clients, and I am open to engagements, project-based contracts and full-time remote positions.
