https://seyitahmetyasar.com.trHow far can a physical business be automated without turning the people inside it into operators of software?enhttps://seyitahmetyasar.com.tr/work/sayapp/https://seyitahmetyasar.com.tr/work/sayapp/One operating layer for a working business: the application the field uses, the console the office uses, and the notification channel that keeps the two in the same minute.https://seyitahmetyasar.com.tr/work/kilif-sepeti/https://seyitahmetyasar.com.tr/work/kilif-sepeti/A physical retail business — stores, a service counter, staff, stock, cash and a ledger — rebuilt as one operating model. The storefront is a surface on top of it, not the thing itself.https://seyitahmetyasar.com.tr/work/service-os/https://seyitahmetyasar.com.tr/work/service-os/Intake to invoice for a technical service business — job records, customer notification, printable legal documents, and a licensing layer so the same system can run for more than one company.https://seyitahmetyasar.com.tr/work/sayhesap/https://seyitahmetyasar.com.tr/work/sayhesap/Current accounts, stock, banks, cash, cheques, invoices, point of sale, warehouse and production orders as one modular application — rather than nine screens that disagree with each other.https://seyitahmetyasar.com.tr/work/magaza-ops/https://seyitahmetyasar.com.tr/work/magaza-ops/Shift handovers, cash counts, target tracking, expenses, labels, training and onboarding — the actual day of a store floor, installed as an app on the staff's own phones.https://seyitahmetyasar.com.tr/work/yonetim/https://seyitahmetyasar.com.tr/work/yonetim/Tasks and reports for the people who run the operation: one service holding the work, one cross-platform client delivering it to whoever has to do it.https://seyitahmetyasar.com.tr/now/https://seyitahmetyasar.com.tr/now/How far can a physical business be automated without turning the people inside it into operators of software?https://seyitahmetyasar.com.tr/decisions/#dec-001https://seyitahmetyasar.com.tr/decisions/#dec-001The counter was already taking devices in every day, and the records it produced were the only history the service desk had. A rewrite would have meant a day on which both were true at once: the old system no longer trusted, the new one not yet proven.https://seyitahmetyasar.com.tr/decisions/#dec-002https://seyitahmetyasar.com.tr/decisions/#dec-002The accounting database is old and it is not going anywhere: it is what the ledger, the tax record and years of history are written in. Moving it would have been a data project with no operational payoff.https://seyitahmetyasar.com.tr/decisions/#dec-003https://seyitahmetyasar.com.tr/decisions/#dec-003A store's network is not a promise. The shift still opens, the till is still counted and the customer is still standing there when the connection is not.https://seyitahmetyasar.com.tr/decisions/#dec-004https://seyitahmetyasar.com.tr/decisions/#dec-004Operations do not stop for a migration. Every system here was introduced next to the process it replaced and took over gradually, which means there was always a working path through the day.https://seyitahmetyasar.com.tr/decisions/#dec-005https://seyitahmetyasar.com.tr/decisions/#dec-005The test for a feature is not whether someone asked for it. It is whether a manual step disappears the day it ships — a phone call, a second entry, a sheet someone was keeping on the side.https://seyitahmetyasar.com.tr/lab/#agent-assisted-engineeringhttps://seyitahmetyasar.com.tr/lab/#agent-assisted-engineeringRunning a codebase through AI agents as a repeatable workflow: written specs, architectural audits and migrations executed as reviewable passes instead of ad-hoc prompting.https://seyitahmetyasar.com.tr/lab/#catalogue-generationhttps://seyitahmetyasar.com.tr/lab/#catalogue-generationTurning spreadsheet exports into a browsable product archive: CSV to structured JSON, an image fetch and repair pass, and a generated showcase built from the result.https://seyitahmetyasar.com.tr/lab/#margin-toolshttps://seyitahmetyasar.com.tr/lab/#margin-toolsSmall calculators for the questions e-commerce asks daily and answers badly: landed cost, commission, and what is actually left after a marketplace has taken its share.https://seyitahmetyasar.com.tr/lab/#document-automationhttps://seyitahmetyasar.com.tr/lab/#document-automationInvoice, declaration and franchise paperwork generated from records rather than retyped from them, with a cache so a document is produced once and reused.https://seyitahmetyasar.com.tr/lab/#payroll-calculatorhttps://seyitahmetyasar.com.tr/lab/#payroll-calculatorA single-purpose front end over a payroll calculation API — built to find out how small a useful internal tool is allowed to be.https://seyitahmetyasar.com.tr/lab/#dealer-archivehttps://seyitahmetyasar.com.tr/lab/#dealer-archiveA dealer-facing archive and cockpit, wrapped as an installable Android build. Kept here as a record of an approach rather than as a live system.https://seyitahmetyasar.com.tr/lab/#media-cataloguehttps://seyitahmetyasar.com.tr/lab/#media-catalogueA catalogue and streaming-metadata experiment on a conventional web framework — an excuse to work on provider abstractions away from anything operational.https://seyitahmetyasar.com.tr/lab/constellation/https://seyitahmetyasar.com.tr/lab/constellation/A canvas mesh of spring-mass nodes that answers the cursor — a pointer-physics sketch, kept for the interaction rather than any product it belongs to.https://seyitahmetyasar.com.tr/lab/sayapp-hero/https://seyitahmetyasar.com.tr/lab/sayapp-hero/A single-product spotlight component — eyebrow, statement, one action, one real screenshot — built to promote the one system on this page with an actual sign-in: SAYAPP.
