Hi, I’m Igor Shatalkin 👋
Co-founder & CEO at SSFS, speeding up developers' pre- and post-generation work with AI coding agents. Developers upload everything relevant to a task — analytics, files, transcripts — and SSFS turns it into a specification and an implementation plan for any ACP-compatible coding agent. When the agent is done, SSFS checks the code against the spec and reports what has been implemented, what hasn't, and what still needs a human look. We build SSFS with SSFS. First public version ships in November 2026.
SSFS
SSFS automates the work around AI code generation through spec-driven development: from task materials to a reviewed specification and plan, then from the agent's output to a report of what matches the spec. Our goal is to cut the time developers spend writing prompts and verifying AI output by 10× or more.
- AI agents made writing code faster, but the bottleneck is shifting from writing code to reviewing it
- 12 of 14 developers we interviewed reported problems reviewing AI-generated code — one spent 5–10 minutes generating code and four hours polishing it
- Coding agents are flexible but don't ship best practices; spec-driven kits need setup; integrated tools drown developers in long specs and trivial approvals
- Built an MVP that we both use daily — we build SSFS with SSFS
- Interviewed 14 developers; 38 LinkedIn conversations turned into 10 interviews with developers we didn't know before
- Pivoted from procurement software to developer tools in September 2026, where we know the problem firsthand
- Joining Founder Institute, batch starting November 11
Senior Java developer who designed and built complex backend systems at Modeus, an enterprise EdTech platform for universities.
- Led the technical implementation of a major project involving an optimization algorithm with a large set of constraints
- Improved critical backend processes by 2–17×
- Optimized a PL/pgSQL data migration from 5 hours to 50 seconds
- Upgraded Java/Spring across multiple services and shared libraries
Why Me
I've been developing enterprise software for over 15 years, and I stayed a hands-on developer even while running a C# department. Along the way I built and co-developed open-source .NET libraries with over a million NuGet downloads and contributed to projects like Hugging Face chat-ui and Moq.
In 2025 I led the rollout of an internal LLM platform that 58% of a 300-person software company adopted, saving them 13–19% of their working time. In 2026 I led my own dev team's transition to AI-assisted coding — and hit the wall every team hits: agents write code in minutes, then developers spend hours writing prompts up front and reviewing, fixing, and testing the output afterwards.
I've also been a founder since I was 20: a chain of 5 retail shops run entirely remotely, an employer-backed EdTech product that drew 40K sessions in two months, and an e-commerce business that grew profit 15× in a year. My co-founder and I first went after procurement software, but we lacked the domain expertise to know which questions to ask. With developers, we do.
That's why we're building SSFS — a structured workflow that takes developers from requirements to verified code with far less manual effort, instead of making them manage the process itself.
We're looking for our first users. If you use Codex, Claude Code, or Cursor every day and spend more time on prompts and review than you'd like, get in touch — I'll trade 30 minutes of your time for early access.
Experience
Spec-driven development tool that speeds up developers' work before and after AI code generation.
- Started with BuyPilot, an AI procurement platform; 150 emails and 11 LinkedIn messages produced just 3 interviews with purchasing managers
- Pivoted to developer tools in September 2026 and built the SSFS MVP, now used daily to build SSFS itself
- Interviewed 14 developers, 12 of whom reported problems reviewing AI-generated code
Employer-backed EdTech product designed to help parents effortlessly verify and review their children's homework.
- Drove 40,000 user sessions in 2 months with nearly zero marketing spend
- Ranked #1 in organic search on Yandex (the primary search engine in Russia) for our top target keywords
- Surveyed 1,000 parents and ran 16 deep customer-development interviews
- Secured $35K internal build budget from employer to launch as a dedicated product venture (not external VC)
- Shut down after clear evidence of insufficient willingness to pay
E-commerce business specializing in consumer electronics on Wildberries, the leading CIS marketplace.
- Built and operated a profitable e-commerce business from scratch
- Invested my own savings and raised an equal amount of external funding
- Spent year one in the red; iterated on pricing, sourcing, and promotion until the business hit profitability
- Grew revenue 4× and net profit 15× YoY (2025 vs. 2024)
- Managed supplier sourcing, inventory planning, pricing, advertising, and logistics
- Currently winding the business down to focus full-time on SSFS
Retail electronics business specializing in GPS navigation and multimedia players.
- Launched my first retail business at age 20, scaling to 5 physical shops in my hometown
- Built custom inventory and management systems to run operations 100% remotely, at a time when typical small businesses required daily on-site founder presence
- Got into one of the city's largest malls when it had no retail space available by renting a promotional-campaign slot and running the shop there
Custis is a 300-person company building enterprise systems across FinTech, EdTech, and Supply Chain Management. 12+ years as a hands-on developer, including while heading the C# Department.
- Led the 2025 rollout of an internal LLM platform used by 58% of employees, saving an estimated 13–19% of their working time
- In 2026, led my dev team's transition to AI-assisted coding; now expanding AI adoption to business analysts
- Built and co-developed .NET libraries with 1M+ cumulative NuGet downloads: EF Migration Generation Extensions, Lightbox, Oracle Idempotent SQL Generator
- Contributed to Hugging Face chat-ui, Moq, and Microsoft Configuration Builders
Worked on both sides of the software business — building it and selling it.
- Sold software through cold calling, gaining hands-on experience with B2B customer acquisition
- That experience inspired my PhD thesis on how IT reduces a firm's transaction costs, including the cost of acquiring customers
Speaking & Writing
- In 2021, co-delivered one of just 8 talks selected as the “Most memorable talks of 10 years of DotNext” — the largest .NET conference in the CIS region (~30 talks/year), whose past speakers include Scott Hanselman (Microsoft), Jon Skeet (Google), and Jeffrey Richter (author of CLR via C#)
