LOCAL MAN SHIPS
entire stack — alone, on time.

Fullstack engineer, founder, designer and recovering security analyst does the work of a five-person team — and answers his own email.

by A. Perliński, himselfreply in 48h — promiseest. 2018

SZCZECIN — Sources close to the matter confirm that one engineer continues to design, build, ship and secure production software with no handoffs and no committee. Eight years in, the operation spans Python and .NET by day, Rust by temperament, and static sites at a flat fee for anyone tired of retainers.

Witnesses describe long-running client relationships ("years, not months"), two products founded this spring, and a security past that still audits everything it touches. Asked for comment, the engineer replied within 48 hours, as promised.

The full portfolio — case studies, classifieds and one Shopify app currently awaiting review — continues on the following pages. Readers are advised to bring their own problem; quotes are free.

A decade of shipped software — marketplaces, web3, healthtech and b2b, mostly under NDA — alongside my own products (GrowKido, AdsDetective, ShelfIQ) and a long-running run with STX Next (fifth year, 9+ projects, .NET & Python).

The full dossier — products, long-term clients and anonymised case files — is filed next door.

The scary decision? Call me.

Architecture you can't un-pick, the migration that could sink the quarter, the hire you can't un-make. Bring the hard one — I've made the mistake already.

Wireframes, clickable prototypes, a tidy design system. The user-experience pass that makes a thing feel built, not bolted together.

In an earlier edition we described the subject as "a five-person team." He is, in fact, one person. We regret nothing.
