Custom software development

We design and build custom applications around real workflows — from on-call schedules and document management to meter readings, integrations and data automation.

What custom application development is

Custom development means building software around your real operational processes, instead of forcing processes into off-the-shelf tools.

We study how your organization actually works and create solutions that automate routine work, reduce errors and centralize data.

Process automation

Remove manual routine, reduce errors and speed up the team.

Unified data & roles

Centralize data, access control, audit trail and change history.

Integrations & APIs

Connect CRM/ERP, billing, IoT, external services and webhooks.

Security & scalability

Architecture for growth, resilience and practical security patterns.

Who this service is for

This service is a fit if you have specific operational needs that are not covered by standard products.

Organizations with complex internal workflows
Municipal services, utilities, healthcare and education

Companies dealing with schedules, approvals or reporting
Businesses with IoT, meters or external APIs

How we can help

End-to-end delivery: from discovery and prototype to implementation, integrations and support.

Discovery & problem definition

Understand the workflow, define roles, constraints, risks and success criteria.

UX/UI & prototyping

Design user journeys, prototype screens and validate the logic before development.

Web application development

Client portal, admin panel, roles, reports, notifications and business logic.

APIs & integrations

REST/GraphQL, webhooks, integrations with CRM/ERP, billing and external services.

IoT & data collection

Meters/sensors, data ingestion, history storage, analytics and reporting.

Go-live & ongoing support

Launch, documentation, training, SLA, updates and continuous improvement.

Architecture & quality

Maintainable code, documentation, clear structure and engineering standards.

Security by default

Roles, auditing, logs, access control and OWASP practices.

Platforms & technology

We build on a proven stack focused on security, scalability and long-term maintainability.

Back-end: Laravel (PHP) — portals, internal systems, APIs
Back-end: Python (FastAPI) — services, analytics, IoT, integrations
REST / GraphQL APIs, webhooks, queues and schedulers
Front-end: Next.js / React — fast, scalable user interfaces
UI/UX: Tailwind CSS, shadcn/ui — modern design system
Data & infra: MySQL / PostgreSQL + Docker, CI/CD, staging/production
Integrations: CRM/ERP, billing, payments, external APIs, IoT
Security & scale: RBAC, audit logs, monitoring, updates

How we work

Typical delivery time: 2–8 weeks depending on complexity.

Workflow analysis

Map processes, users, data flows and bottlenecks.

Solution design

Architecture, UX journeys, data models and integrations.

Development

Backend, frontend, integrations and business logic.

Testing & refinement

Functional testing, security checks and iterations.

Go-live & support

Launch, documentation and ongoing evolution.

Solution examples

A few typical scenarios and how we solve them.

On-call scheduling & staff roles

−30% errors

Workflow RBAC Reports

Проблема

Schedules are maintained manually in spreadsheets; changes and substitutions are hard to track.

Решение

Built a web system with roles, approvals, audit trail and exports.

Результат

Fewer errors and transparent change history.

Meter readings portal & data integration

↑ speed

IoT API Portal

Проблема

Data entry is fragmented; readings end up in multiple systems and get lost.

Решение

Client portal + API layer + validation + history and notifications.

Результат

Single source of truth and less manual work.

External registries & system integrations

↓ incidents

Integrations Queues Logging

Проблема

No reliable data exchange: errors, duplicates and missing logging.

Решение

Integration layer with queues, retries, logging and error control.

Результат

Stable integrations and predictable operations.

EXPERT

Common mistakes

These mistakes usually lead to higher costs, timeline slips and long-term maintenance issues.

No workflow definition (only “build something”)

Requirements are not formalized: roles, scenarios, edge cases and data.

Impact:

Delays and constant rework.

Automating chaos

The process is not cleaned up, but a “button” is expected to fix it.

Impact:

The system will replicate the chaos and frustrate users.

No role model and access control

Everyone sees everything; no audit trail and no separation of duties.

Impact:

Security risks and harder compliance.

“Direct” integrations without resilience

No retries, queues, logging or error handling discipline.

Impact:

Hidden failures, duplicates and data loss.

No monitoring and logging

Incidents are discovered by users, not by the system.

Impact:

Longer downtime and more expensive support.

No maintenance & evolution plan

After go-live there is no SOP, SLA, backlog or product owner.

Impact:

The system quickly becomes outdated and “abandoned”.

If you want, we start with a short discovery (1–2 sessions) and a prototype — it clarifies scope and budget faster.

FAQ

Can you integrate with existing systems?

Yes. We regularly integrate accounting systems, sensors, APIs and internal databases.

Who owns the source code?

You own the source code unless agreed otherwise.

Can the system be extended later?

Yes. We design solutions with scalability and future growth in mind.

How long does development take?

Typically 2–8 weeks depending on scope, integrations and number of roles. A quick prototype can be done in 1–2 weeks.
