Profile

AI agents write all of my code. My job is deciding what's worth building and answering for what runs in production. I understand business and tech. 10+ years building software, nearly 4,200 merged pull requests on GitHub since 2017, 7 years on a SaaS product that 60,000+ people used every day.

Who I help

Business owners
Your people retype the same data between email, Excel and an old system? I build custom software with AI agents for the routine work, and the code and data are yours from day one. We start with one process, and after launch we at Digitaliko keep the system running.
CTOs and engineering leads
The backlog keeps growing and the team already uses AI agents, but everyone differently and it's not getting faster? I set up an AI-native SDLC: shared rules, a harness and CI gates for the whole team. From week one I work in your repo and your code review.
Founders
Your AI-built prototype breaks with real users? I audit it and tell you honestly what to fix and what to rebuild. Then we take it to production so it holds up.

What I bring

AI-native delivery that holds in production
Rules, hooks and CI gates around AI agents, spec-first work, AI-assisted TDD, agent review. AI writes the code, tests and gates decide what ships.
AI agents that take over routine work
Agents with tools, RAG and MCP servers that read your systems, do the repetitive work and hand the exceptions to a person.
Working inside other teams
Their repo, their review and release process, from week one; 7 years in one SaaS team, contracts in product teams since.
Reworking a live product
Rebuilt a SaaS frontend used by 60,000+ people every day without stopping the business, then brought AI features into it.
Integrations with systems that have no good API
Integrations and data pipelines, migrations from legacy systems with a parallel run.
Architecture and product judgment
Deciding what's worth building, domain modelling, one codebase for many markets or tenants, white-label and role-based access.
Regulated and financial environments
Analytics for a regulated industry, financial statements, auth provider migrations, audit-friendly code.
