PRODUCT ENGINEERING SERVICES

Build web applications. Fix production problems. Modernize what already works.

Product engineering for bespoke web delivery: Next.js and TypeScript builds, API integration, production debugging and modernization when an existing system is the constraint. I work on both new products and live codebases — diagnosing broken flows, resolving auth issues, connecting third-party systems and improving the layer that actually needs changing. Stack serves the outcome, not the other way around.

PRIMARY SERVICE SYSTEM

Three ways I can help.

01PRIMARY CATEGORY

Websites & Web Application Development

Bespoke product engineering for business websites and web applications that need custom functionality — portals, dashboards, admin tools and booking or workflow systems. Typical delivery uses Next.js and TypeScript with backend APIs, data models, authentication and third-party integrations implemented as one coherent product surface.

Scope Ledger

01.1Business websites requiring custom functionality and dynamic flows

01.2Web applications, customer portals and client dashboards

01.3Admin systems, internal tools and operational business workflows

01.4Booking or workflow-heavy systems where off-the-shelf tools no longer fit cleanly

01.5Next.js/TypeScript frontend & backend: UI, APIs, database, authentication and server architecture

01.6Extending or modernizing an existing website or web app without an unnecessary full rewrite

02PRIMARY CATEGORY

Production Debugging & Technical Fixes

Websites and web applications that are already built and live often need a focused fix rather than a rebuild. The work starts in the existing codebase, not a blank one. I investigate the failure boundary first, then work on the smallest layer that actually needs changing, whether the problem is in a user flow, authentication, an integration, browser/device behavior, backend logic or technical debt blocking delivery.

Scope Ledger

02.1Production bugs and broken user flows

02.2Authentication, session and browser/device issues

02.3API or third-party integration failures

02.4Frontend/backend/data issues that cross system boundaries

02.5Technical debt that has become a concrete delivery or day-to-day-use blocker

03PRIMARY CATEGORY

Integrations, Migrations & Modernization

When an existing system has useful logic worth keeping, I prefer improving the constrained layer instead of rewriting everything by default. That can mean connecting third-party APIs, replacing fragile dependencies, moving data or platforms, cleaning up architecture, or modernizing CMS setups into purpose-built web apps.

Scope Ledger

03.1Third-party/API integrations and integration cleanup

03.2Dependency replacement without breaking working downstream systems

03.3Platform, CMS and database migrations

03.4WordPress/CMS-to-custom-app migration when business workflows outgrow the CMS

03.5Architecture and maintainability cleanup

03.6Focused performance or UX improvements where scope can be defined and verified

SUPPORTING PLATFORM LAYER

Platforms can be part of the solution. They are not the positioning.

I use the platform that fits the job rather than turning a technology name into the service. Shopify, WordPress and API work can sit inside the three core problem categories above.

COMMERCE CONTEXT

Shopify

Shopify is a supporting implementation lane when the store or service-commerce model already fits the platform. Relevant work can include custom Liquid sections/templates, service or product-page systems, structured-data implementation, integrations and technical improvements without pretending every commerce problem needs a custom platform.

CMS / CONTENT CONTEXT

WordPress

WordPress is appropriate when the job is content-centric or the existing site still fits the business. I can build, fix or extend WordPress implementations, and I can also help move a workflow-heavy product to a custom application when the CMS has become the constraint.

SYSTEM INTERFACE

APIs & integrations

API work can appear across all three service categories: implementing a new backend flow, repairing a broken integration, connecting systems, or replacing a dependency. The integration should solve a real product or operational problem, not exist as an isolated technology showcase.

ENGAGEMENT QUALIFICATION

Where this work fits best.

FIT / 01

Owner-led business or founder

You have a real digital-product or technical gap to solve, but building a full internal engineering team would be unnecessary for the problem in front of you. You need someone who can understand the context and implement the work directly.

DIRECT FIT

FIT / 02

Agency or technical team

You need dependable implementation capacity for a bounded project, feature, debugging problem, integration, migration or delivery partnership without adding a permanent hire for every temporary gap.

See the agency partner page

DIRECT FIT

BOUNDARY / 03

Not the primary fit

Pure brand/visual-design engagements, standalone SEO or paid-media retainers, native-mobile specialist work, and cloud/DevOps/security consulting as the primary mandate are not the core offer on this page. If a project touches one of those areas inside a broader implementation scope, it should be scoped honestly rather than promoted as a standalone specialty.

SCOPE BOUNDARY

DECISION & DELIVERY MODEL

What working together looks like.

An explicit, honest engineering process designed around clarity, trade-off visibility, and risk-appropriate verification.

STAGE 01

1. Clarify the problem

Start with what exists today, what is not working or needs to be built, who it affects, and what a useful outcome would look like. Existing code, screenshots, logs, designs or project context help when they are relevant.

STAGE 02

2. Scope the smallest sensible step

If the problem is already clear, the work can be scoped directly. If important unknowns would make an implementation estimate irresponsible, define a bounded discovery or technical review first rather than pretending the whole project is already known.

STAGE 03

3. Implement with the trade-offs visible

I work hands-on and keep important technical decisions, dependencies and blockers explicit as implementation moves. The goal is to solve the defined problem without quietly expanding the scope or rebuilding working parts just because a different architecture is possible.

STAGE 04

4. Verify and hand off

Verification should match the risk and scope: test the critical flows, check the agreed behavior, document the relevant decisions/setup, and deploy or hand off according to the engagement. Any ongoing maintenance or support should be separately agreed rather than implied as an unlimited default.

TECHNICAL FIT CHECK

Not sure whether this is a fix, migration or rebuild?

Send the current problem and enough context to understand what exists today. I will tell you whether the sensible next step looks like a focused fix, an integration, a migration, a rebuild, or a deeper paid technical audit.

This is not a free code audit, security review, architecture report or implementation plan. It is a practical read on fit and the smallest honest next step.

Request a Technical Fit Check

Fix
A bounded production problem, broken flow, auth issue, or integration failure with a clear repair surface.
Integration
Systems need to connect cleanly without turning the whole product into a rewrite.
Migration
A dependency, data path, or platform layer needs replacing while preserving what still works.
Rebuild
The current foundation no longer fits the operational workflows the business actually runs.
Paid technical audit
Important unknowns would make a full implementation estimate irresponsible until a bounded audit clarifies the next step.

Have a product or technical problem that needs a clear next step?

Send what exists today, what is blocking you and what a good outcome looks like. From there we can run a Technical Fit Check and decide whether the next step is a fix, integration, migration, rebuild or a scoped paid technical review.
