When the Roadmap Outgrows the Team

Senior Capacity
Without the Hiring Wait

Before: Stuck, Stretched or Stalled

A deadline, a legacy codebase nobody wants to touch, or a decision that needs more experience than the team has right now.

After: Moving Again

An experienced engineer inside your team — shipping, unblocking, and leaving the codebase better than they found it.

What People Say

Trusted Inside Large Engineering Teams

  • Five out of five stars

    “Bach worked extremely well with the external vendor and UX designer to retrofit our Online Banking Portal. Many thought it was impossible due to the outdated technology it was built on, but Bach used his frontend expertise to bring our portal to a modern state in a very short time. He helped us quickly deliver more value to our customers while saving cost and time.”

    “At CommSec, Bach demonstrated his expertise as our most experienced front-end engineer by tackling complex projects with proficiency. He collaborated closely with engineers and the UX/VD team, bringing ideas to life. Bach consistently offered valuable improvements and delivered challenging UI designs. When the UX team started working on a Design System, Bach eagerly volunteered and delivered a great component library. His calm, measured approach made him a pleasure to work with, and he always prioritized delivering the best results for our customers. I would have no hesitation in working with him again.”

    “Bach transformed our cloud application into a cutting-edge React application, significantly reducing unexpected bugs. The robust frontend foundation he established enabled our team to expand rapidly and deliver new features quickly. I highly recommend Bach for any team looking to develop a modern, state-of-the-art SaaS application.”

    “In my experience working with Bach at CommSec, his contributions to the frontend and UX were outstanding. He consistently communicated effectively and delivered UI features promptly, which was key to our team meeting deadlines at very high quality.”

  • Five out of five stars

    “Bach is a fantastic developer to work with. He’s consistent, adaptable, and truly cares about the code he writes. On a rebranding project for a large medical web application, Bach dug into implementation details, experimented with CSS techniques for complex design elements, and kept the project on track and on time. When designs were too complicated or expensive to implement, he negotiated workable compromises with stakeholders. Bach is self-sufficient, diligent, and dependable. If I ever have the opportunity to work with him again, I will go out of my way to make it happen.”

He excels in front-end development and has extensive knowledge of frameworks and web standards. As a great team player, he became the go-to person for anything related to JavaScript. I would not hesitate to recommend him.”

FAQs

Questions About Senior Engineer On Demand

What do you work on?

Web applications: React and Next.js front ends, Node.js services, APIs and third-party integrations, performance, and modernising older code.

How do engagements work?

By contract, by sprint or on retainer. We agree the scope, availability and rate in the first conversation, before anything starts.

Can you work inside our codebase and process?

Yes. The background is Agile product teams at Cochlear, CommSec and Pepper Money — your repository, your reviews, your tooling.

Can you help with legacy systems?

Yes — it's a large part of the background: refactoring a legacy codebase onto React at Cochlear, and retrofitting an internet banking portal for mobile at Pepper Money.

What if it isn't the right fit?

Then we'll say so in the first conversation, and point you somewhere better if we can.
