Everything a modern
web product needs.
From the first component to multi tenant scale, we build web and SaaS applications the way serious software teams do.
Multi Tenant Architecture
Secure tenant isolation, role based access, and per customer configuration baked into the foundation, not bolted on later.
Modern Frontend
React and Next.js with server side rendering, fast hydration, and component libraries your team can actually maintain.
Scalable APIs
Node.js REST and GraphQL backends with caching, rate limiting, and pagination designed for growth.
Subscriptions & Billing
Stripe powered plans, metered usage, trials, and dunning, wired into your product, not faked with spreadsheets.
Auth & Permissions
SSO, social login, MFA, and granular role based access control that passes security review.
Built In Analytics
Product analytics, audit logs, and admin dashboards so you can see what users do and act on it.
Custom web applications for how your business actually runs.
Before we write any code, we take the time to understand your business, users, and goals. That foundation helps us design web and SaaS applications with an architecture built for reliability, scalability, and future growth.
B2B SaaS Product Development
End to end SaaS product development for founders and product teams, from idea validation and clickable prototype to a revenue generating multi tenant platform. We handle subscription billing, onboarding flows, admin panels, and the unglamorous plumbing like webhooks, background jobs, and email infrastructure. That plumbing is what separates a demo from a product customers actually pay for. When your platform grows into something bigger, our enterprise application development team takes it the rest of the way.
MVP Development for Startups
An MVP is not a smaller product. It is the fastest honest test of your core assumption. We scope a focused v1 around one core workflow, authentication, billing, and a dashboard, so you can put a working product in front of real users in weeks. Then you gather data and decide what to build next with evidence instead of guesses.
Customer Portals & Client Dashboards
Secure self service customer portals that cut support tickets and manual work: account management, document sharing, order and status tracking, payments, and role based access. If your team is still emailing spreadsheets to clients, a portal usually pays for itself within the first year. Pair it with a sales or support chatbot and your customers get answers before your team even wakes up.
Internal Tools & Business Process Automation
Custom internal web applications that replace the spreadsheet and email workflows slowing your operations down. Think approval systems, inventory and job tracking, reporting dashboards, and admin tooling wired straight into your existing data. Where a workflow can run itself, we bring in operations automation so your team stops doing robot work.
Legacy Application Modernization
We take over aging PHP, .NET, jQuery era, or no code systems and modernize them step by step. The stack moves to React, Next.js, and Node.js on cloud infrastructure without a risky big bang rewrite. You keep running on the old system while the new one proves itself piece by piece. Read more about how we approach migrations and modernization across platforms.
API Development & Third Party Integrations
REST and GraphQL APIs with documentation, versioning, authentication, and rate limiting. Whether you are exposing your product data to partners or connecting your platform to Stripe, CRMs, ERPs, or payment gateways, our dedicated API development and integrations practice handles it. For companies running Salesforce or ServiceNow, we also build custom extensions on those platforms.
Multi Tenant or Single Tenant? We Will Tell You Straight.
Multi tenant SaaS architecture, meaning one codebase with isolated data per customer, keeps hosting costs low and shipping fast. It is the right default for most SaaS products. Single tenant deployments make sense when enterprise clients demand dedicated infrastructure or strict data residency. Retrofitting multi tenancy later is one of the most expensive mistakes in SaaS. We architect it correctly on day one.
Build for Today, Architect for Scale.
We design cloud native applications with DevOps baked in on AWS or Azure, with horizontal scaling, caching, and CI/CD pipelines from the first sprint. The version that launches to 100 users runs on the same architecture that serves 100,000. No rewrite in between.
From idea to shipped product.
A focused build process that gets a usable product in front of real users fast, then iterates.
Discovery & Scope
We map user journeys, data models, and the must have feature set, and cut everything that is not v1.
Architecture & Design
We design the stack, schema, and UI system, then deliver a clickable prototype and a technical spec.
Iterative Build
Two week sprints with working demos. You see and steer the product as it comes together.
Launch & Scale
We ship to production with CI/CD, monitoring, and a roadmap for the next iteration.
Cost, timeline, and ownership,
before you ever get on a call.
These are the questions every founder and CTO asks before hiring a web application development company. We answer them here, with real numbers and trade offs, instead of saving them for the sales call.
A focused SaaS MVP typically costs $15,000 to $60,000. A mid tier platform with integrations, role based access control, and analytics runs $60,000 to $150,000. Enterprise SaaS with compliance, SSO, and custom AI features starts at $150,000 and up. The biggest cost drivers are feature complexity, integrations, and compliance requirements, not the tech stack. After a discovery call we give you a fixed, itemized estimate, so the number you sign is the number you pay.
A well scoped MVP ships in 6 to 12 weeks. Medium complexity web applications take 3 to 6 months. Enterprise platforms take 6 to 12 months. We work in two week sprints with working demos, so you are never waiting until the end to see your product. You steer it while it is being built.
You do. All of it. Every line of code, every design file, and every credential lives in repositories and cloud accounts registered to your company from day one. There is no vendor lock in, no licensing fee, and no hostage negotiation if you ever decide to bring development in house.
Security is designed in, not audited in later. Every build ships with encrypted data at rest and in transit, MFA and SSO ready authentication built on zero trust identity principles, granular role based access control, audit logging, and OWASP aligned coding practices. Before launch, our security assessment and penetration testing team attacks the product the way a real attacker would. For regulated industries we architect for GDPR, SOC 2, and HIPAA readiness from the schema up, because retrofitting compliance costs multiples of building it in.
Here is the honest number most agencies avoid: plan for 15 to 25 percent of your initial build cost per year for maintenance, security patches, dependency updates, and iteration. We offer flexible post launch support, covering monitoring, uptime, bug fixes, and a feature roadmap through our cloud and DevOps services. Or we hand over clean, documented code your in house team can run with. Your choice, and it is stated in the contract.
Yes, and in 2026 most SaaS buyers expect it. We build enterprise AI agents and integrate LLM powered features like intelligent search, document processing, chat assistants, and workflow automation using API based models. That keeps your costs proportional to usage instead of demanding a six figure ML investment upfront, and our AI cost optimization work keeps it that way as you scale. If your product handles European user data, we build it as a GDPR compliant AI system from the start. And we will tell you when AI is the wrong answer, because not every feature needs a model behind it.
It should. Every product we build includes product analytics, audit logs, and admin dashboards as standard. When you need to go deeper, our data engineering and analytics team builds the pipelines and reporting layer that turn raw usage data into decisions. If your web platform needs to talk to an ERP, our ERP implementation team makes sure both systems agree on the numbers.
Still have a question we did not answer? That is what the discovery call is for. No pitch, just an engineer and an honest scope.
Questions about
Web & SaaS Applications
React and Next.js on the frontend, Node.js (and Python where it fits) on the backend, Postgres for data, and AWS or Azure for infrastructure. We pick proven tools your team can hire for and maintain.
Yes. We start with an architecture and code review, document what is there, and improve it incrementally, no risky big bang rewrites unless they are genuinely warranted.
A focused MVP typically ships in eight to twelve weeks. We scope hard to a real first version, get it in front of users, and build from evidence instead of guesswork.
We do. Every build ships with CI/CD pipelines, infrastructure as code, monitoring, and backups. See our Cloud Native & DevOps offering.
That is the point. We design for multi tenancy, horizontal scaling, and caching from the start, so growth is a configuration change, not a rewrite.
