The software SDEN designed, built, and
runs in production.

SDEN designs, builds, secures, and operates four SaaS products: Real Estate (real estate), Lead Manager (sales automation), Beauty (salon management), and University Portal (education). They are the engineering proof of what we deliver to clients.

Four SaaS products

SDEN's own SaaS products are the proof of the engineering we sell. Each one is designed, built, secured, and operated by SDEN end-to-end, and used in production by real businesses. We do not ship marketing decks as evidence; we ship products you can navigate to, use, and form your own opinion about.

The four products below cover four different sectors (real estate, sales automation, salon and wellness, higher education) and four different operational shapes (multi-tenant B2B SaaS, AI-augmented workflow tool, schedule-driven point-of-sale, role-based academic platform). The technical surface is wide on purpose. The lesson is the same: the production discipline is the engineering, not the framework, not the stack, not the slide deck.

The proof philosophy

Why we
run our own products.

Consulting can teach you to recommend. Only operating production software teaches you what survives. The reason SDEN runs its own SaaS products, even though we are a services-led company, is to keep our engineering honest against the pressures that only show up after launch: real customers paying real money, support tickets that arrive faster than the engineering team can plan around, security disclosures from researchers who do not care about our roadmap, and the slow accumulation of small architectural decisions that decide whether the product can still ship a feature three years from now.

Every client engagement inherits that operational scar tissue. When we recommend a database engine, we are recommending one we have run under load. When we choose a deployment topology, it is the version we wish someone had recommended to us before we shipped the first one. When we propose a security control, the threat model behind it has been validated against actual disclosures, not just textbooks. Running our own products is the most expensive way to learn that, and it is also the most direct way to be sure we are not selling our clients a stack we would not run ourselves.

Real Estate: all-in-one real-estate platform

Real Estate unifies the whole sales cycle in one white-label product: SEO listings and an interactive map, a CRM that matches buyers to properties, AI home staging that valorizes a listing from a single photo, AI-assisted valuation, and an isolated client portal for e-signature and document tracking.

Real-estate agencies historically juggle four to six tools (a CRM, a listings spreadsheet, an e-signature service, a separate document store, sometimes a valuation tool, sometimes a property-tour booking calendar) and the work of reconciling them lives in the agent's head. Real Estate unifies those tools into a single product where listings, properties, contacts, and transactions share one data model. The agent stops re-entering the same information across systems; the agency stops losing transactions to administrative friction.

The architecture is a Next.js application backed by a typed NestJS API and PostgreSQL with per-tenant isolation. AI-assisted valuation is a Python pipeline trained on property characteristics and market history; it produces an explainable range rather than a single point estimate, and the agent's adjustment is logged so the model improves over time. AI home staging runs as a generative image pipeline (furnishing, emptying, or decluttering a room from a single photo) queued and rendered asynchronously, with a before/after comparator on the listing. The client portal is a separately hosted surface with no access to any other listing's data; multi-tenant isolation is enforced at the type level, not just at the query level.

The result is that an agency that adopts Real Estate replaces a stack of disconnected tools with one product, and the work of reconciliation disappears. The exact figures below are illustrative until we publish audited customer outcomes.

University Portal: higher-education platform

University Portal unifies the entire academic lifecycle (courses, exams, theses, internships, events, messaging, and notifications) in one role-aware platform, with a built-in AI assistant that adapts to each of five user roles.

Higher-education institutions still run academics on paper and disconnected spreadsheets: enrollment in one place, grades in another, schedules in a third, and no shared channel between administration, faculty, and students. University Portal replaces that with a single platform where courses, exams, theses, internships, and events share one data model, and where each of five roles (administrator, director, professor, student, staff) gets an interface scoped to exactly what it may see and do.

The architecture is a Next.js application backed by a typed NestJS API and PostgreSQL with Prisma. Role-based access is enforced at the type level rather than hidden in the UI, audit logs and two-factor authentication are wired in, and a real-time layer (server-sent notifications, web push, instant messaging) keeps everyone on one channel. The AI tier is a role-scoped assistant built on a hosted LLM with a curated toolset (natural-language search, document summaries, revision plans, proactive alerts) each tool restricted to the data the calling role is allowed to touch.

The result is that an institution adopting University Portal collapses hours of repetitive admin, makes a student's path traceable in real time, and gives every role an assistant grounded in real data rather than a generic chatbot. The figures are illustrative until we publish audited customer outcomes.

Coming next

What we are
building next.

SDEN is selectively expanding the product roster into sectors where we see a recurring engineering need that off-the-shelf SaaS does not serve well. Candidates under active development include vertical-specific applications in regulated industries and operational tooling for small teams that have outgrown spreadsheets but cannot justify a salesforce-scale platform. Specifics are deliberately withheld until the products are ready to operate in production: the proof philosophy goes both ways.
