Technology stack

We choose technology for your problem-not the reverse. What we use every day.

04 - Transparent every step

How we work

Five clear stages. Demos every two weeks. You see the code, access tasks and builds. You know exactly what you're paying for.

01

Discovery

We understand your task, users, competitors. Define requirements, lock budget and timeline.

02

Design

Architecture, mockups, prototypes. Approved before any code-no costly rewrites later.

03

Development

Two-week sprints. Code review, tests, demos continuously. Working code in your repo same day.

04

QA & stability

Functional, integration, load testing. We ship only production-ready code.

05

Launch & support

Deploy, configure monitoring. Warranty period, technical support, ongoing development available.

05 - People who deliver

Founders.
Engineers.

No middlemen diluting information. You speak directly with the CTO, CEO and tech leads who solve your problem.

Nikolay Solonenko

CEO · Chief Executive Officer

6 years in the IT business. He started as a developer, then moved into management: leading project teams, building development processes, and owning client and business relationships. He combines technical understanding with the commercial side - estimation, negotiation, timeline and budget management. He takes on the admin and the communication so you don’t lose time or nerves on it. His principle: “I answer for the result with my own name and face” - no hidden costs, no surprise deadlines, no murky communication.

Anastas Smekh

CTO · Chief Technology Officer

8+ years building complex digital products. For most of his career a product tech lead in travel: he ran the mobile track (iOS, Android, watchOS), built Go backends, and set up the processes for a team of up to 10 engineers. He has shipped dozens of production apps with real-time processing, external API integrations, and cross-device sync. Strongest in native mobile development (Swift, SwiftUI, Kotlin, Jetpack Compose, KMP) and Go. He owns architecture, security, and quality - personally designing solutions, choosing the stack, and reviewing critical components.

Lev Minakov

DevOps TeamLead · Infrastructure

3+ years in mission-critical systems. He progressed from network engineer through SRE and DevOps to Senior DevOps / MLOps in large corporate systems (names under NDA). He has automated infrastructure from scratch: Kubernetes, full GitOps CI/CD (GitLab CI + ArgoCD), IaC (OpenTofu, Ansible), monitoring and alerting. Notable results: service uptime from 89% to 99.9%, deploys from a week to one hour, engineer onboarding from 3 days to 3 hours, and $2M in freed resources. Credo: “99.99% uptime is a planned goal, not a dream.”

And we won't fake them.

S2 Digital is a young studio. Our first public cases and references are taking shape right now - from real projects we stand behind by name. That's why we take on a few projects on special terms: you get a strong team and the founders' attention, we get our first honest case.

FAQ - Questions & answers

FAQ

Everything important about working with S2 Digital.

What is S2 Digital?
A full-cycle development studio. You bring an idea-we ship a production product. Web, mobile, backend, AI, Web3, SaaS, DevOps. One team, one contact (our CEO), full accountability.
How do I start?
Form on the site or Telegram @s2digital. Within 24 hours you get: possible approaches, rough timeline and budget, and a free consultation.
What do I get as the deliverable?
Source code, documentation, repository and infrastructure access-everything transfers to you. Zero vendor lock-in after launch. Plus 30–90 day warranty and optional ongoing support.
What's the cost?
Cost depends on scope, platforms and complexity. After a short conversation we fix a transparent estimate of timeline and budget - before work starts. First consultation is free.
Do I need a finished spec?
No. When there's no spec, we run the analysis ourselves, define an MVP, propose architecture. Just describe the task, target users and budget.
How long does it take?
Landing page: 2–6 weeks. MVP web/mobile: 2–4 months. App with backend: 3–6 months. Complex systems (AI, Web3, high-load): 6–12+ months. Exact range after discovery.
Can the project drag on?
No-timeline and phases are locked in the contract. If requirements change, timelines change too, but we agree on that upfront. You see progress every two weeks, so delays won't appear.
What if you disappear?
The process is built so this isn't a risk: you work directly with the founders, code and tasks live in your repositories, and the contract is split into stages with staged payment. Even in the worst case you can continue with another team without losing anything.
Do you work with international clients?
Yes-Russia, CIS, Europe, Asia, North America. Documentation in Russian and English, communication in your timezone. International projects have a dedicated s2digital.tech site.
What is full-cycle development?
Full-cycle development means one team owns the product from the first idea to a shipped release and ongoing support, with no hand-offs between vendors. The cycle covers discovery and requirements, UX research and design, architecture, frontend and backend development, QA, deployment and maintenance. You talk to a single team accountable for the outcome, so the risks at the seams between stages disappear. That is exactly how we run every project at S2 Digital - see the Cases section for examples.
How is a studio different from a freelancer?
A freelancer covers a single role - frontend only, or design only - and every risk rests on that one person: illness, vacation or leaving stalls the project. A studio gives you a team of interchangeable specialists, an established process, code review and contractual accountability for the result. For a product that needs design, backend and infrastructure at the same time, a studio covers the whole cycle without you stitching vendors together by hand. We work exactly as one turnkey team.
Why is outsourcing development worth it?
Outsourcing gives you a ready-made team of the right composition without the cost of hiring, onboarding and keeping people on staff. You pay for outcomes and a defined scope rather than idle time between tasks, and you can scale the team up or down to fit the project stage. You also get external expertise across many stacks at once - frontend, backend, mobile, DevOps and AI in one place. It is faster and more predictable than assembling engineers one by one.
