Technical Lead for Founders

The most expensive decisions in software get made before anyone understands the problem.

Founders invest in premium infrastructure when the real bottleneck is a database query. They hire developers to build features the architecture underneath can't support. They rewrite systems when the actual risk is in one decision made in year one that nobody questioned.

That's the work. Understanding the problem is the work. Everything after that is execution.

In June 2022, Crewfare's co-founder hired me to fix a preloader. I couldn't fix it. I told him and didn't charge for the time. While I was in the system, I found the real issue. That conversation became three years as technical lead — architecting their multi-tenant SaaS platform from scratch, building billing infrastructure Stripe's subscriptions can't replicate, and leading the engineering team through an acquisition.

"The kind of developer you can hand a hard problem to and trust that it'll come back solved — not worked around."

— Jordan Scheffler, Co-founder (Forbes 30 Under 30), Crewfare

Two stacks meet in my work: AI systems built with deterministic code and LLM orchestration — RAG, agents, document intelligence — and the long-lived PHP, Laravel, and WordPress platforms that already carry revenue or funded users. Both need the same first move: understand the system before touching it. temsilci.pro — a B2B representative-search product on the Claude API — is mine, end-to-end. Claude Code and Cursor are in my daily production work.

First step

Start with a technical second opinion.

Before you rebuild, refactor, hire, ship, or add AI, bring the system and the decision you're about to make. The work is finding the real constraint, the risk behind it, and the next move that protects the business. Sometimes that means a technical lead. Sometimes an implementation pass. Sometimes it means not building yet.
