Service 03 — Web App Development
Web apps built to scale.
An MVP that can't survive its first hundred users is a prototype, not a product. We design and engineer web applications — SaaS platforms, customer portals, dashboards, and internal tools — with the architecture, security, and testing discipline to grow from first launch to serious scale.

Overview
Software engineering, not just web development
Websites present information. Web applications run operations — billing, user accounts, real-time data, complex workflows. That difference demands real software engineering: specifications, architecture decisions, automated testing, and security reviews. That's how we build.
From MVP to SaaS: products that survive success
The graveyard of startups is full of MVPs built fast and rebuilt from scratch the moment they found traction. We scope MVPs ruthlessly — one core user journey, done brilliantly — but architect them for the product they'll become. That means modular code structure that can evolve toward services as you grow, database schemas designed with tomorrow's features in mind, and API-first thinking so mobile apps and integrations plug in later without surgery.
For SaaS products, we build multi-tenancy correctly from day one: tenant isolation in the data layer, subscription billing (typically via Stripe) with plan management and usage metering, admin tooling for support and operations, and onboarding flows engineered to activate trial users. Your MVP launches as a business, not a demo — ready to charge money, support customers, and scale past the founding team's capacity.
Dashboards, portals, and the tools teams actually use
Not every web app faces the public. We build the operational software businesses run on: customer portals that deflect support tickets, analytics dashboards that turn raw data into decisions, booking and scheduling systems, inventory and order management, and internal admin tools that replace fragile spreadsheets. These projects live or die on UX — a dashboard nobody opens is a failed dashboard — so our designers obsess over information hierarchy, role-based views, and workflows mapped to how your team actually works.
Under the hood, we integrate with the systems you already use: CRMs, payment gateways, email and SMS providers, accounting software, and third-party APIs. Data flows where it should, automatically, with audit trails and role-based access control so the right people see the right things — and nothing they shouldn't.
Security, scalability, and engineering discipline
We follow OWASP secure-coding practices as standard: parameterized queries and ORM usage against injection attacks, modern password hashing, CSRF and XSS protections, encrypted data in transit and at rest, and secrets managed in proper vaults — never hardcoded. Authentication supports role-based access, social login, and multi-factor options where the risk profile demands it. Every release passes a security review checklist before it touches production.
On scalability, we build for horizontal growth: stateless application tiers, caching strategies (Redis, CDN layers), database indexing and query optimization, and background job queues for heavy work. Deployments run through CI/CD pipelines with staging environments, automated test suites on critical paths, and rollback procedures — so releases are boring, predictable events instead of launch-day gambles.
What's included
Full-cycle product engineering
- Product discovery & scoping Requirements workshops, user stories, and a fixed written spec — no vague estimates.
- UX/UI design Wireframes to polished interfaces, designed for the workflows your users repeat daily.
- Frontend development Responsive, accessible interfaces in React or Next.js — fast, testable, maintainable.
- Backend & API development Robust server logic and REST/GraphQL APIs in Node.js, Python, or Laravel.
- Database architecture PostgreSQL/MySQL schemas designed for integrity, performance, and future features.
- Third-party integrations Stripe billing, CRMs, email/SMS, analytics, and custom API connections.
- Authentication & RBAC Secure login, social auth, MFA options, and role-based access control.
- Automated testing & QA Test suites on critical paths plus manual QA across browsers and devices.
- CI/CD & cloud deployment Pipelines with staging environments on AWS, Google Cloud, or DigitalOcean.
- Documentation & handover Architecture docs, API references, and runbooks — your team can take over anytime.
How we work
Agile, transparent, demo-driven
- Discovery & technical spec We map requirements into user stories and a written specification with fixed pricing — you know exactly what you're buying.
- UX & architecture Design and system architecture proceed in parallel, so interfaces and engineering never contradict each other.
- Agile sprints Two-week sprints with working demos. You see real, testable software every fortnight — not progress reports.
- QA & security review Automated tests, manual QA, and a security checklist gate every release before staging sign-off.
- Staged launch Controlled rollout with monitoring, so issues surface in minutes and rollbacks take seconds.
- Support & iteration Warranty period, then optional support plans or continued sprint cycles as your product evolves.
Why Tayr Digital
A product team, not a ticket queue
Software projects fail on communication more than on code. You get a dedicated product-minded team that challenges your assumptions early — when changes cost hours, not weeks. We'd rather spend a discovery workshop killing a bad feature than spend three sprints building it.
And because we're also a digital agency, we think beyond the build: how users will find your product, how onboarding converts trials, how analytics inform the roadmap. Your web app launches with go-to-market thinking baked in, not as an afterthought handed to a different vendor.
FAQ
Web app questions, answered straight
How long does an MVP take, and how do you approach cost?+
A focused MVP typically takes 8–12 weeks from approved spec to launch. We scope MVPs ruthlessly around one core user journey, quote fixed pricing against a written specification, and build in two-week sprints with working demos — so cost stays tied to shipped, testable software rather than open-ended hours.
Which technologies do you build with?+
We work with modern, proven stacks: React and Next.js on the frontend; Node.js, Python, or PHP/Laravel on the backend; PostgreSQL and MySQL databases; and cloud deployment on AWS, Google Cloud, or DigitalOcean with CI/CD pipelines. We choose the stack that fits your product's needs, hiring market, and budget — and we document everything so you're never locked to us.
How do you handle security?+
Security is engineered in, not audited on. We follow OWASP practices: parameterized queries and ORM usage against injection, bcrypt/Argon2 password hashing, CSRF and XSS protections, role-based access control, encrypted data in transit and at rest, and secrets managed outside the codebase. Every release passes a security review checklist, and we can arrange independent penetration testing for regulated or high-risk products.
Can you take over our existing codebase?+
Yes. We start with a code audit — architecture, test coverage, dependencies, security posture, and technical debt — then give you an honest verdict: continue, refactor, or rebuild, with the trade-offs priced. If we take over, the first sprint establishes CI/CD, staging environments, and documentation so future work is predictable.
What happens after launch?+
Every build includes a warranty period for defects, plus optional support plans covering monitoring, uptime response, security patches, dependency updates, and ongoing feature development in sprint cycles. Your app keeps evolving with your business instead of quietly decaying.
Do you build SaaS products?+
Yes — multi-tenant SaaS is one of our core build types. We architect tenant isolation, subscription billing (typically Stripe), usage metering, admin tooling, and onboarding flows from day one, so your MVP can grow into a real business without a rewrite.
