Senior Software Engineer

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. Two months later, I was responsible for the product — multi-tenant SaaS architecture from scratch, billing infrastructure Stripe's subscriptions can't replicate, and the engineering team. As the sale approached, responsibility transitioned and I left. Before the sale closed, they brought me back to prepare the product for acquisition and transfer it to the next company. The acquiring company made my continued involvement a condition of proceeding — and the work continued after transfer.

"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

My work splits into two kinds of systems: AI engineering where the output must be verifiable before anyone trusts it, and long-lived platforms that already carry revenue or funded users. Both need the same first move: understand the system before touching it. Mütalaa, an AI legal-research product I built, has one hard rule: no verified evidence, no answer. temsilci.pro gives each business an assistant grounded in its own material — ingestion, retrieval, and chat built end to end on the Claude API.

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.
