01 / Services

Three ways
to work together.

01 / EMBEDDED

Staff augmentation for existing teams

Drop me into your squad. Standups, PRs, Slack — the works. Senior-level throughput without headcount drama.
Part-time Full-time 3+ months
02 / PROJECT

End-to-end delivery, fixed scope

You have a thing that needs building. I scope it, build it, ship it. Clean handover. No surprises on the invoice.
Fixed price 4–12 weeks MVPs
03 / TECHNICAL

Advisory  & code rescue

Architecture reviews, stack decisions, cleaning up legacy messes, unblocking stuck teams. By the hour or retainer.
Hourly Retainer Workshops
02 / Approach
I work like a senior IC, not a consultant. That means writing code on day one, pushing back on bad ideas, and knowing when to stop. No decks. No discovery phases that charge you for reading the brief.

CASE 01
In-flight
Automotive services / Embedded

Online booking platform for a major auto-glass franchise

Senior frontend engineer on the customer-facing appointment platform. Angular SPA, deep integrations with the service-network and scheduling backend. Fully integrated into the in-house team's Scrum cadence — daily, planning, refinement, retro, review, all remote.

Angular TypeScript Embedded
CASE 02
Live
Hospitality SaaS / Solo build

Reservation management app for a restaurant-tech provider

Built solo, end-to-end. Visual floor plans, drag-and-drop tables, real-time timeline of reservations and turn-around. Shipped to the App Store and Play Store.

Flutter iOS Android Solo
CASE 03
Live
Internal tooling / Same SaaS

Whitelabel app generator — onboarded clients in hours, not weeks

Designed and built a generator that produces branded mobile apps automatically for the SaaS's restaurant clients. What was a multi-week manual project per customer became a parameterized pipeline.

Ionic Automation Tooling
CASE 04
Live
Hospitality SaaS / Conversational AI

WhatsApp AI assistant — one bot per venue, on the restaurant's own landline

Each restaurant on the SaaS hooks its existing landline up to a WhatsApp Business account; the AI bot then takes reservations and answers questions about the menu and venue. NestJS backend, multi-model routing via AWS Bedrock (Claude Haiku, Amazon Nova) — each model where it's strongest.

goes down.

Written proposal: what gets built, timeline, price, what's out of scope. Fixed or T&M — your call.

Kickoff & build

Access to repos, weekly demos, async updates. I work in your tools — Linear, Slack, GitHub, wherever you live.
Usually within 2 weeks
