I combine engineering discipline withintelligent, secure and usabledigital systems.

From idea to working prototype; from research to clear user experience.

I’m Seyid Berat Ergün, a fourth-year Computer Engineering student at TED University and an early-career developer. My primary direction is AI systems, machine-learning foundations, cybersecurity and secure software. Separately, I build applied product experience in Flutter/Dart, REST APIs, responsive web interfaces, testing and debugging.

01 · PROFESSIONAL PROFILE

A clear primary focus and a separate applied-development track.

Fourth-year Computer Engineering student at TED University and early-career developer. The main direction is AI systems, machine-learning foundations, cybersecurity and secure software; Flutter, APIs, web, testing and debugging form a separate applied product-development track.

I turn academic foundations in algorithms, data structures, software engineering, databases and programming languages into practical product decisions.

During my 2025 internship in the software department of an established health-technology organisation in Türkiye, I worked on modular Flutter/Dart UI, REST APIs, responsive implementation from Figma, scenario testing, debugging and performance improvement.

I develop AI prototypes and TryHackMe-based security practice through principles of data responsibility, human approval, testability and clear usage boundaries.

The final fee is confirmed in writing after screens, integrations, content, delivery time and revisions are known.

Transparent pricing and academic-support note

USD and EUR values are approximate daily ECB conversions; the accepted quote is fixed in the selected currency. Domains, hosting and paid services are separate. Mentoring focuses on explanation, planning, review and debugging; the student remains academically responsible for submitted work.

WORKING & QUOTE TERMS

A clear framework that protects both sides.

Website information is not a binding order or contract. Work begins only after scope, total price, tax/document treatment, delivery, revisions and responsibilities are accepted in writing.

01
Quote & contract

A form or email is only an enquiry. The service becomes definite after the written quote or contract is accepted.

02
Scope & delivery

Deliverables, timing, communication, acceptance criteria and responsibilities are written in the quote.

03
Total price & records

Taxes and third-party costs such as domains, hosting, store accounts, licences and paid APIs are shown before acceptance; the legally required document is issued.

04
Revisions & change

Included revisions are defined; out-of-scope requests require separate timing and fees.

05
Content & access responsibility

The client confirms the right to provide supplied text, media, data, accounts and access.

06
Ethical & secure use

Unauthorised access, harmful use and producing assessed work on a student's behalf are outside scope; mentoring supports learning.

07
Withdrawal & start of performance

For consumer work, pre-contract information, withdrawal rights and any request to start before the withdrawal period ends are handled for that project.

08
IP & cancellation

Source files, licence, payment schedule, cancellation/refund terms and support are defined per proposal.

This is general information, not legal advice or a standalone contract. Professional legal review is recommended before commercial use.

Short original notes make my learning, implementation boundaries and engineering decisions visible.

AI / GUIDE4 MIN READ

Where do AI agents genuinely create value?

Beyond impressive demos: a concise guide to automation, tool use, human approval and security boundaries in real scenarios.

SECURITY / GUIDE4 MIN READ

Why are passkeys beginning to replace passwords?

A plain-language look at passwordless sign-in, what it improves for users and which common security problems it reduces.

MOBILE / NOTES4 MIN READ

What changes when a Flutter prototype becomes a product?

Why architecture, state, APIs, testing and performance become critical when moving beyond demo screens.

Software Engineering3 MIN READ

Why is testing more than ‘looking for bugs’?

A good testing approach does more than check whether an application crashes. It helps reveal the paths users can take, the effect of unexpected input and whether a change breaks previously working behaviour. Even in small projects, scenario-based thinking makes problems visible before they become expensive to solve.

AI / Evaluation4 MIN READ

What do I check before calling an AI feature ‘working’?

A model producing an answer is not enough to prove success. Consistency, hallucination risk, instruction following, sensitive-information boundaries and contribution to the real task should be evaluated together. In AI products, evaluation is one of the engineering steps that separates an impressive demo from genuinely reliable use.

08 · FREQUENTLY ASKED QUESTIONS

Professional answers that build confidence before work begins.

Scope, communication, academic guidance, security approach and pricing.

Is the SBE Digital Assistant real live support?

It is an automated information assistant that instantly matches typed questions to services, pricing, AI, cybersecurity, experience and contact information. It stores no messages, does not pose as a human, and directs detailed requests to Gmail.

What working standard can I expect?

Every engagement uses a clear scope, written deliverables, regular communication, an early visible draft and basic testing. Early-career pricing keeps the process agile while this structure protects professional quality.

How does coursework and project mentoring work?

We first break down the question and learning goal. I then support the student through concept explanation, algorithm planning, example approaches, code review, debugging and presentation preparation.

How can you help with cybersecurity?

My TryHackMe labs and secure-software studies support basic risk checks, test scenarios, input validation, failure-flow review and security-awareness recommendations. I can also help identify the right specialist service when formal assessment is required.

Which languages and channels can we use?

We can communicate directly in Turkish and English. Start through Gmail and review my work on GitHub and LinkedIn. The interface is also available in Spanish, Italian and German.

Can launch, domain and hosting be included?

Domain selection, DNS, hosting setup, basic SEO, performance checks and short post-launch support can be added according to scope.

How are prices and conversions determined?

TRY figures are starting prices. USD and EUR are approximate daily ECB conversions. Once screens, integrations, content, timing and revisions are clear, a written quote is fixed in the selected currency.
