A senior engineer. On your team.
Some work is not one feature. It is a roadmap: a continuous stream of connected features over two to six months. A sequence of separate sprints would work, but it is not the cleanest fit. An embedded engineer is.
You get a senior engineer matched to your stack, working inside your team, your tools, and your standups, with Saurav reviewing behind them and a second engineer to pair when the work is hard. It is the continuity of a hire without the recruiting cost, the 12-month contract, or the conversion fee.
How embedded engagements run.
A weekly cadence
Monday scopes the week, Friday reviews it. The engineer plans their own work against your roadmap, in your tracker.
Daily in your Slack
The embedded engineer is present in your channels and your standups every working day. Not a vendor you email, a teammate you talk to.
A written monthly review
Once a month, a clear written account of what shipped, what is next, and where the engagement stands. No surprises.
Founder review behind them
Saurav reviews the engineer’s work and a second Holdfast engineer is on call to pair when something is hard. You get a team, not a contractor.
Three kinds of senior.
Senior backend engineer
Owns the work where a bug is also a refund: billing, reconciliation, payments, schema. Deterministic, auditable, careful.
Senior frontend engineer
Builds interfaces that feel hand-made: real design tokens, accessible components, and motion that looks considered.
AI integration specialist
Builds AI features that know when to refuse, with an eval harness your team can keep tuning after handoff.
The model we refuse.
- No junior engineers. Every embedded engineer is senior, full stop.
- No waterfall project managers. The engineer manages their own delivery.
- No offshore-only black box. You meet the engineer and work alongside them.
- No 12-month lock-in. Month to month, 30-day notice, no penalty.
Eleven thousand a month.
Sprint
Fixed price- One production-ready feature, scope locked on day 0.
- Written money-back guarantee if we miss day 14.
- Daily commits, twice-weekly Loom updates, async Slack.
- A senior engineer named in your contract, founder reviewing.
- Full handoff: production deploy, README, 10-minute video.
Best for: a specific feature, integration, or workflow you need shipped now.
Embedded team
Month to month- A senior engineer embedded in your team, tools, and standups.
- Month to month, 30-day notice, no minimum term.
- Weekly cadence, daily Slack, a written monthly review.
- Zero conversion fee if you later hire them full-time.
- Founder review and a second engineer to pair when needed.
Best for: a continuous workload of 2 to 6 months.
An engagement, written up.
Embedded questions.
You get a senior engineer plus Holdfast behind them: Saurav reviewing, a second engineer to pair when needed, and our toolchain and delivery discipline. You get the continuity of a hire without the 12-month contract or the recruiting cost.
