BUILD BETTER.
SHIP FASTER.

Senior product engineering for founders and growing teams — either as your embedded tech lead, or as the team that builds your product end to end. AI-assisted workflow tools and SaaS products that save your business real hours every week, without the overhead of a traditional agency.

Your product has outgrown the way you're building it.

The idea is good. The team is busy. The roadmap keeps moving. But shipping is harder than it should be.

ZELN brings product thinking, engineering depth and delivery leadership together to get you from "we should build this" to "it's live."

No $100k agency retainer. No hand-off between strategy and delivery. Just senior ownership of the work that matters, at a fraction of the overhead.

Two ways to work with us.

Pick the engagement that fits — embedded technical leadership, or a full product build delivered end to end. Not sure which? Start with an audit.

TECH LEAD_

Embedded technical & product leadership.

We slot in as your fractional tech lead — owning architecture, delivery and the product roadmap alongside your team. Not just code review from the sidelines: real decisions, real ownership, product and delivery woven in from day one.

  • Fractional technical leadership
  • Product & delivery planning, combined
  • Architecture & technical direction
  • Team organisation & process improvement
  • Mentoring, hiring & technical assessment
  • AI / automation strategy

Good for: Teams with engineers but no senior technical owner.

BUILD_

End-to-end product delivery.

A full build, delivered by a senior-led team — not a 40-person agency with account managers and a six-month onboarding process. We lead every engagement personally and bring in trusted specialists when a build needs more hands, so you get real delivery capacity without the overhead of a traditional agency retainer.

  • AI-assisted workflow & automation tools
  • SaaS product builds, idea to paying customers
  • Product discovery & technical definition
  • Web & mobile application development
  • API, backend & integrations
  • Testing, CI/CD & production launch

Good for: Teams with no engineers, or who need to move faster than their team can build.

AUDIT

Not sure which fits, or just want a second opinion? An AUDIT is a clear, outside review of your product, engineering and AI opportunities — with a prioritised plan, not a report that gathers dust.

FROM IDEA
TO PRODUCTION.

Fast doesn't have to mean fragile. We keep scope tight, decisions clear and engineering standards high.

DISCOVER

Understand the user, business goal and constraints. Challenge assumptions before code.

DEFINE

Turn the problem into a focused product scope, technical approach and delivery plan we agree on together.

BUILD

Design and engineer the product with one senior lead, bringing in trusted specialists when the build needs more hands. Weekly demos and direct access — no disappearing into a dark room for months.

SHIP

Deploy, instrument and launch. Then stick around to monitor performance, squash bugs and iterate on real user feedback.

DISCOVERY 1–2 weeks Scope, UX, architecture & delivery plan
BUILD / LAUNCH 4–10 weeks Focused, production-ready product or MVP
BUILD / SCALE 8–16+ weeks Major build, senior-led and scaled with trusted specialists

Projects are scoped around outcomes, not arbitrary day counts. Pricing is shaped by complexity, scope and the seniority required.

/ A GOOD FIT

For teams that
need momentum.

✓ Founder-led or growing software businesses

✓ Small product & engineering teams

✓ New products, major features or stalled roadmaps

✓ Teams that need senior ownership, not more tickets completed

✓ Businesses that want AI/automation done properly, not bolted on

✓ Anyone who wants agency-level delivery without agency-level overhead

Z_

Senior enough to lead.
Hands-on enough to build.

10+ years building and scaling SaaS products across healthtech, edtech, B2B and B2C — from hands-on engineering through technical leadership.

I work where product, engineering and people overlap. That means I can zoom into the code, zoom out to the roadmap, and keep the team moving between the two.

Every engagement is led by me, personally — no handing you off to a junior once the contract's signed. For full BUILD projects I bring in trusted specialists as needed, so you get the capacity of a team without the overhead of a traditional agency.
