Engineering service tiers built for daily business operations.

Internal consoles, client portals, and automated data pipelines form our core practice. Every project is executed by Ivan Petrov with transparent milestone fees between $5,000 and $50,000, or hourly rates from $75 to $160.

Custom Web Service Development for internal tools and business operations.

Turnkey business web applications automate warehouse coordination, client billing, and staff reporting. Project budgets land between $15,000 and $50,000, strictly within our operator range of $5,000 to $50,000. Deployment of an initial operational version takes one to two weeks.

Automated regression test suite executing inside a development terminal
Monthly production support retainers with guaranteed Service Level Agreements.

Operating web applications require proactive dependency patching, automated regression test runs, and continuous uptime telemetry. We back live software through monthly retainers ranging from $250 to $1,500 per month, guaranteeing critical response windows under two hours.

Sprint debugging console with execution benchmarks and memory profiling
Hourly full-stack developer support for targeted database and API refactoring.

When an existing application crawls during peak traffic or integrations drop records, we audit the code and optimize indexes. Work is billed transparently at $75 to $160 per hour, verified by commit logs and direct sprint reviews with Ivan Petrov.

What our formal project quote depends on

We evaluate every potential engagement against six concrete operational drivers. No speculative markups.

Criterion 01
Architectural Complexity

Monolithic internal consoles require simpler database state machines than multi-tenant SaaS tools with tenant data segregation and background workers.

Criterion 02
Documented Scope & Schemas

Projects with existing entity relationship models and documented user flows enter rapid 1–2 week sprints without upfront discovery cycles.

Criterion 03
Dedicated Engineering Tier

All architectural design and primary codebase development is led directly by Ivan Petrov, active in commercial software delivery since 2018.

Criterion 04
Third-Party Integrations

Connecting external payment processors (Stripe), legacy ERP databases, accounting packages, or custom hardware endpoints adds integration testing rungs.

Criterion 05
Target Platform Architecture

Node.js and TypeScript services with PostgreSQL, Python microservices, or headless CMS backends differ in build and testing requirements.

Criterion 06
Incident Response SLA

Critical 24/7 business-critical monitoring with sub-2-hour response windows scales the monthly retainer between $250 and $1,500 per month.
