Web applications we develop

We develop web applications tailored to specific business needs. We consider workflows, data structure, access rights, and integrations. If a project requires AI, we build it into the architecture from the start: we define scenarios, restrict data access, and establish quality criteria and control rules.

Enterprise web apps

We develop corporate web applications for internal operations and complex processes. These include ERP, CRM, HRM, billing systems, approval systems, and other tools that underpin a company’s daily operations. We also add AI features when needed: internal assistants, corporate content search, document management, and automation of routine tasks based on roles and access rights.

MVPs and AI PoCs

We help startups and product teams launch MVPs and AI PoCs to validate their ideas before full development. At this stage, we evaluate the use case, technical feasibility, support costs, and the path to the next release. Such a project may include chat interfaces, knowledge-base search, document processing, and highly specialized task-specific assistants.

Internet of Things solutions

We build IoT web applications for device monitoring, sensor data handling, operational dashboards, and remote system control. We also develop AI applications for anomaly detection, maintenance support, event interpretation, and data-driven recommendations based on live and historical machine data.

SaaS product development

We design and develop SaaS products with tenant-aware architecture, admin controls, integration layers, and stable release foundations. AI can be added to these products for support automation, content handling, account insights, usage analysis, and embedded assistants that work within each tenant’s data boundaries.

Super apps

We provide development and consulting services for building all-in-one platforms that integrate multiple services—e-commerce, banking, communication, and transportation—into a unified ecosystem. Super apps eliminate the need for multiple standalone applications and are designed to handle high traffic and diverse functionality.

    Our web development approach

    We run custom web application development through a structured process that covers scope, team setup, cost control, and post-launch support. When AI is part of the product, we extend SDLC with ADLC, so use case design, data preparation, evaluation, and rollout are handled inside the same process.

    Project scoping

    We define product goals, business requirements, AI scope, and delivery boundaries before development starts.
    Run stakeholder interviews and workshops to shape the product vision
    Document user flows, business rules, integration points, and success metrics
    Define where AI fits in the product and where deterministic logic should stay in control
    Prepare a roadmap with milestones, release scope, dependencies, and priorities

    Project resource allocation

    We assign the team structure based on product scope, architecture choices, AI workload, and delivery pace.
    Match frontend, backend, QA, and DevOps roles to the build plan
    Add AI engineers or data specialists for retrieval systems, agent workflows, model routing, or evaluation tooling
    Plan team load by phase, release window, workload, and technical risk
    Adjust staffing as the scope, priorities, timelines, or architecture change

    Project cost estimation

    We estimate costs against scope, team mix, infrastructure choices, and AI usage patterns.
    Break costs down by phase, role, environment, and release stage
    Account for cloud services, third-party tools, model calls, and vector storage where AI is in scope
    Show what can change the estimate and what assumptions it depends on
    Revisit the estimate when scope or architecture changes

    Risk management

    We track delivery, security, integration, and AI-specific risks from the first phase to release.
    Identify risks tied to dependencies, legacy systems, data quality, and access control
    Define fallback logic for model output, retrieval failure, cache misses, and service degradation
    Set review points for security, privacy, compliance, and release readiness
    Record issues, owners, mitigation steps, and escalation paths

    Knowledge management & sharing

    We document the system so your team can support, extend, audit, and govern it after release.
    Keep architecture notes, API documentation, decision logs, and runbooks up to date
    Document AI use cases, prompt logic, evaluation rules, and model access patterns
    Share delivery knowledge through demos, handovers, working sessions, and recorded walkthroughs
    Prepare technical guidance for scaling, maintenance, support, and onboarding

    Code review

    We review code for maintainability, security, performance, and fit with the agreed architecture.
    Check business logic, test coverage, integration quality, and security checks before release
    Review model-facing code, retrieval pipelines, guardrails, and access rules in AI-enabled features
    Enforce coding standards, naming rules, repository discipline, and review workflow
    Address defects early to reduce rework later.

    Reporting

    We keep reporting structured so the team can track progress, risks, spend, and release status.
    Share delivery updates with completed work, next steps, blockers, and decisions
    Report on scope changes, milestone status, budget impact, and risk shifts
    Include ADLC signals such as evaluation results, output quality, drift signals, and rollout readiness when AI is in scope
    Keep records aligned with your internal reporting format

    Post-launch warranty

    We support the product after release and fix issues tied to the agreed scope.
    Monitor defects, regressions, integration issues, and performance drops after go-live
    Stabilize AI features through evaluation updates, retrieval tuning, guardrail refinement, and prompt adjustments
    Provide support within the warranty terms and response model
    Help plan the next release based on product usage and support input

    Predictable operating costs

    AI features can distort a web product’s cost profile if each request triggers a heavy model call. We design for control from the start:
    Semantic caching for repeated queries
    Background processing for non-urgent tasks
    Routing rules that send simple requests to lighter models
    Retrieval tuning so prompts stay smaller and more relevant
    Admin controls for tenant-level or user-level usage limits.

    FAQ

    What makes your custom web application development services different when AI is in scope?
    Most teams can build a web interface and connect it to an API. The harder part is designing the backend, data flow, permissions, monitoring, and rollout model so AI features strengthen the product. We handle the web platform and the AI layer together.
    Can you build a custom web app that is ready for AI, even if we are not adding AI on day one?
    Yes. Many Clients want to modernize the product first, then add AI after the core workflows, data model, and access controls are in better shape. We can prepare the architecture so that later AI integration does not require a full rebuild.
    How do you prevent AI features from exposing sensitive data?
    We define access at the application and data access levels. That includes role-based permissions, protected service boundaries, auditability, and controlled retrieval rules. In regulated environments, we also design data handling flows that restrict what leaves protected systems.
    How do you keep AI features from slowing down the interface?
    We use asynchronous patterns where needed, so the main interface stays responsive while heavier tasks run in the background or stream results progressively. The right approach depends on the use case, latency target, and deployment model.
    Can you build a custom web app that uses open-source models or private model hosting?
    Yes. We can design web applications that connect to public model APIs, private cloud deployments, or self-hosted model infrastructure, depending on the security model, data sensitivity, and performance requirements.
