IT consulting and audits

Discovery, code review, architecture analysis, process audit, risk mapping, and realistic delivery planning.

AI and ML implementation

LLM features, workflow automation, internal copilots, search, classification, summarization, and AI-assisted operations.

Infrastructure refactoring

Legacy cleanup, modularization, performance gains, observability, technical debt reduction, and safer scaling.

DevOps, CI/CD, automation

Release pipelines, cloud environments, monitoring, deployment safety, and better operational reliability.

Firefighting team

Need a specific setup?

Project team, advisory, fractional CTO, or emergency support.

Describe your situation

Why Dev366

Not generic outsourcing. Product thinking, technical rigor, and fast recovery when delivery gets messy.

Product mindset

Decisions are framed around business outcomes, constraints, release risk, and long-term maintainability.

Senior execution

Strong architecture and delivery judgment reduce dead ends and speed up implementation.

Flexible engagement

Consulting, dedicated engineering, rescue squad, product team, or technical leadership support.

UI/UX discipline

Interfaces are built for clarity, accessibility, conversion, and maintainable frontends instead of decorative complexity.

Analytical approach

Audit before scaling, simplify before rewriting, automate where it creates measurable leverage.

When to hire Dev366

You need to launch an MVP fast.
Your product is slowed down by legacy and delivery friction.
Your team needs a technical audit and recovery plan.
You want AI features without adding architectural chaos.
You need experienced engineers to stop a production fire.

Process

Clear delivery model, fast feedback, and no black-box execution.

Discovery

Goals, constraints, risks, product assumptions, architecture context, and delivery priorities.

Solution design

Roadmap, stack, milestones, engagement model, and release plan aligned with business reality.

Build

Iterative implementation with demos, QA, feedback loops, and delivery visibility from week one.

Launch and stabilize

Deployment, monitoring, optimization, handoff, and the next-stage plan for growth or recovery.

Startup MVP

B2B SaaS launch under product and time pressure

Built a pilot-ready MVP with core user flows, admin tools, payment logic, and deployment pipeline.

Goal: Validate an idea fast and get ready for first customers.
Stack: React, Node.js, PostgreSQL, AWS
Result: MVP launched in a short cycle and prepared for pilot onboarding.

Legacy Recovery

Platform stabilization and release process repair

Refactored critical modules, improved CI/CD, reduced release friction, and increased system visibility.

Goal: Stop instability and restore predictable delivery.
Stack: Java, Spring, Docker, Kubernetes, GitHub Actions
Result: Safer releases, fewer incidents, and stronger maintainability.

AI Workflow

Internal assistant for support and knowledge operations

Added AI-powered search, summarization, and controlled workflow automation for internal teams.

Goal: Reduce repetitive work and speed up internal responses.
Stack: Python, FastAPI, vector search, OpenAI-compatible APIs
Result: Lower manual workload and faster access to useful operational knowledge.
