DevSapience Technology Solutions

We build software that does the patient work.

Some jobs are not difficult so much as endless — sitting the same practice paper until the weak topic stops being weak, clicking through the same checkout after every release. We build software for those jobs, and we run it ourselves before we sell it to anybody.

Products

Two products, both live, both free to start

One helps a person get hired. The other keeps the software they end up writing from falling over. Each gives away everything that costs nothing to run, and meters only the part that spends model time.

Examness

Certification and interview preparation

One place to prepare for both gates of a technology career. Exam-style certification practice with explanations and timed mock exams, an interview question bank across more than thirty topics, a Code Lab that runs in your own browser, and AI teachers that begin the lesson from the answers you got wrong.

Wrong answers are kept deliberately — they are what the AI teacher reads before it replies
Code Lab: watch the AI draft a solution, press Stop mid-line, finish it yourself
Reading, practising and running code are free; only AI actions spend credits
Web and mobile, in English, Hindi, Bengali, Japanese and Indonesian

Provelex

Automated QA and security analyst

Point it at your application, prove you are allowed to test it, and read the report. Provelex opens a real browser, works out what the software does, tries to break it, and writes up what it found in language you can forward to somebody who does not write code.

Five suites per run: functionality, security, performance, accessibility, mobile view
No scripts, no selectors, no YAML — a renamed button heals rather than fails
Every finding carries evidence, reproduction steps, business impact and a standards reference
Web, Windows and macOS; the desktop build reaches localhost and private networks

Services

The same engineering, applied to your product

Everything below is work we do on our own products every week. Nothing here is a capability we would be learning at your expense.

AI and LLM application engineering

Assistants grounded in a user's real history rather than a generic prompt, model routing with failover across providers, and metering that shows the price of an action before anybody takes it.

Automated QA and security testing

Browser automation that survives a redesign, OWASP Top 10 and WCAG coverage, Core Web Vitals from the page itself, and reports built to be handed to somebody who has to approve the fix.

Web platform engineering

Production web applications end to end: API, database, authentication, billing ledgers that reconcile, live run streams over WebSocket, and deployment behind automatic HTTPS.

Cross-platform mobile

Android and iOS clients sharing one account, one balance and one backend with the web product, so a person who signs in on a laptop finds their history waiting on a phone.

How each engagement works

How we build

Four decisions we have made in every product so far

Free by default, metered where it costs

Reading, practising, running code, opening pages, taking screenshots and exporting reports cost us close to nothing, so they cost you nothing. Credits buy model time and nothing else. Both products give every new account fifty credits to start with.

The price is shown before the action

Every button that spends says what it spends, the balance stays on screen, and a request that fails is refunded automatically. Nobody should have to check a statement afterwards to find out what something cost.

Show the arithmetic

The Provelex health score is a published formula rather than a proprietary index, and the credit ledger is a list of lines that sum to the balance. A number an auditor cannot reproduce by hand is a number they will not accept, and they are right not to.

Evidence, not assertion

A claim about your software arrives with the screenshot from the moment it happened, the sequence that reproduces it, the standard it maps to, and how confident we are. Findings we are unsure about are marked as such rather than quietly dropped.

Start with whichever problem you have today

Both products are free to try, and neither asks for a card. If you would rather talk about work on your own product, the same people answer that email.
