JAVA & SPRING BOOT ENGINEERING

From MVP to mission-critical: Java engineering that scales with you

We build the backend you won't need to rebuild in 18 months — whether that's a startup's first system or an enterprise migration that can't go down.

WHO WE WORK WITH

Same engineering discipline, three different starting points

The right approach depends on what's actually blocking you — not a one-size-fits-all engagement.

FOR STARTUPS

Ship your MVP without painting yourself into a corner

Move fast now. Don't pay for it in 6 months when you actually have users.

  • Direct access to a senior engineer, not a junior learning on your dime
  • Built for where you'll be in 12 months, not a hypothetical Series B
  • Fixed-price builds — no scope-creep budget surprises

FOR SMBs

Your systems don't need a rewrite. They need to be understood.

Stabilize first. Modernize on your timeline, not ours.

  • We document and stabilize before we change anything
  • No big-rewrite gamble — incremental work, business keeps running
  • Fix the thing that's actually breaking, not a 6-month "transformation"

FOR ENTERPRISE

Engineering you can put in front of compliance

Transparent process, audit-ready documentation, no black-box delivery.

  • Architecture decisions documented as we go, not reconstructed later
  • We integrate with what you have — no unnecessary rip-and-replace
  • You'll know the engineer and process well enough to vouch for both

WHAT WE BUILD

Services

Engineering work, scoped and delivered by the people who actually write the code.

01

Java Development

Custom enterprise applications built on modern Java, maintained by people who understand the whole system.

Java 17/21SpringHibernate
02

Spring Boot Microservices

Scalable microservice architecture, designed for the load you'll actually have — not the load you might.

RESTDockerKubernetesKafka
03

API Development & Integration

Connect systems securely, with documentation a new engineer could pick up without asking us first.

OpenAPISwaggerPayments
04

AI Solutions

AI integrated where it actually solves a problem — chat support, document processing, internal automation.

ChatbotsOpenAI APIAutomation
05

Cloud Migration

Move legacy systems to cloud-native infrastructure without a "big bang" cutover that risks downtime.

06

Architecture Consulting

A second set of senior eyes on a system before you commit budget to building or rebuilding it.

WHY DEVTOKEN.IO

We're not the biggest name. Here's what you get instead.

  • →
    You talk to the engineer who writes your codeNot a sales rep who hands you off to whoever's free.
  • →
    Weekly check-ins, no surprise scope creepYou'll know what's built and what's next, every week.
  • →
    Fixed-price quotes after discoveryNo hourly billing black hole — you know the number before we start.
  • →
    Pilot project optionStart with a 2-week scoped engagement before committing to the full build.
THE GUARANTEE

We respond to every inquiry within 24 hours — not "soon," not "someone will follow up."

If a free architecture review doesn't surface anything useful, you've lost twenty minutes, not a sales cycle.

ENGAGEMENT FLOW

How a project actually moves

01

Discovery

Understand the real problem, not just the feature request.

02

Architecture

A documented technical roadmap, before any code is written.

03

Build

Agile delivery, weekly visibility into what shipped.

04

Test

Quality and security review before anything goes live.

05

Deploy

Production launch, with documentation that outlives us.

06

Support

Ongoing fixes and improvements, scoped up front.

PRICING

Starting points — every quote is finalized after a free discovery call.
