Case studies

The engagements we
have actually shipped.

Case studies of the engineering work SDEN has delivered: from products running in production to regulated client engagements. Product outcomes are real and published; figures from NDA-gated client work are PLACEHOLDER-marked until each client signs off.

Case studies

FintechPLACEHOLDER: approximately seven months end-to-end

Payments / regulated finance

A regulated North American fintech's payments ledger had grown into a single-database approximation the regulator would not accept. We rebuilt it as a typed, append-only, auditable system, and the product never went offline.

HealthtechPLACEHOLDER: approximately nine months end-to-end

Clinical operations / telemedicine

A multi-site North American clinical network needed a patient portal, a clinical workflow, and an end-to-end-encrypted telemedicine surface: with the HIPAA posture and audit trail built from the schema out, not retrofitted before the next inspection.

Real estatePLACEHOLDER: approximately eight months end-to-end

Multi-agency network platform

Four disconnected tools per agency became one product: a multi-tenant platform for a real-estate network (AI-assisted valuation on the Real Estate lineage included) that gave head office its consolidated view without overriding any agency's autonomy.

Real estateApproximately four months from kickoff to full rollout

Residential brokerage / valuations

Days of manual comparative market analysis became explainable estimate ranges at a residential brokerage, once Real Estate's AI-assisted valuation went in, cutting the time spent on each valuation by 70%.

Sales & RevOpsApproximately four months end-to-end

B2B SaaS demand generation

Arrival-order prospecting gave way to ranked, explained leads for a B2B SaaS team once Lead Manager's predictive scoring landed, and reps booked 2.4× as many meetings per hour.

Wellness & local servicesApproximately two months end-to-end

Salon / spa

One-tap confirmation and an automatic waitlist cut missed appointments at an independent salon by 34%, turning last-minute cancellations back into filled chairs.

Wellness & local servicesApproximately three months end-to-end

Wellness studio chain

A wellness studio chain started taking bookings around the clock, secured by Stripe deposits, and bookings placed outside opening hours rose 48%.

EducationApproximately seven months end-to-end

Higher education

Spreadsheets and five disconnected SaaS tools collapsed into one academic suite at a mid-size university, removing roughly 2,000 hours of manual administration a year.
