Terms of Service

1. Parties and scope

This website (turjadev.it.com) and the services offered through it are provided by Turja Talukder, an independent contractor operating as a sole proprietor with its place of business at Rangamati, Chattogram Division, Bangladesh ("we", "us", "the Provider").

These Terms of Service ("Terms") apply to (a) your use of this website and (b) any professional services we provide, unless a separately signed agreement, master services agreement ("MSA") or statement of work ("SOW") says otherwise. If a signed agreement conflicts with these Terms, the signed agreement prevails.

By using this website or engaging us, you confirm you have authority to bind the organisation you represent.

2. Services

We provide software engineering services, which may include: product and platform architecture; full-stack web development; mobile development (Flutter); API design and integration; data automation, extraction and AI-assisted workflows; DevOps, deployment and performance work; technical audits; and fractional technical leadership.

Engagements are delivered in one of these models: fixed-scope project, time-and-materials / dedicated capacity, or monthly retainer. The model, deliverables, assumptions, team composition and price are always recorded in a written proposal or SOW before work starts.

3. Proposals, SOWs and change control

Proposals are valid for 30 days unless stated otherwise and are based on the information you provide. Anything not explicitly listed as a deliverable is out of scope.

Changes to scope, schedule, technology or team composition are handled through a written change request. We will always state the impact on cost and timeline before starting the changed work; work on a change order begins once you approve it in writing (email is sufficient).

4. Fees, invoicing and payment

• Fixed-scope projects are invoiced in milestones — typically 30% on signature, 40% at the mid-project demo, 30% on delivery — unless the SOW states otherwise.
• Retainers and time-and-materials engagements are invoiced monthly in advance.
• Payment terms are NET 15 from the invoice date unless agreed otherwise.
• All fees are exclusive of taxes. You are responsible for any withholding tax, VAT, GST or similar levy applicable in your jurisdiction, and for providing the documentation we need to invoice correctly (for example a W-8BEN-E for US clients).
• Overdue amounts may pause delivery and may attract interest of 1.5% per month or the maximum permitted by law, whichever is lower. Third-party costs (licences, cloud, app-store fees, paid APIs) are passed through at cost with your prior approval.

5. Client responsibilities

Timely delivery depends on you providing, without unreasonable delay:

• a single decision-maker for approvals, and one point of contact for the project;
• access to systems, credentials, repositories, environments and test data;
• written feedback on milestones within five (5) business days;
• confirmation that any content, data or third-party assets you supply are lawfully yours to use, and that processing them does not violate privacy or export law.

Delays caused by missing inputs, unanswered approvals or scope changes may move the schedule and may be billed as idle capacity on retainers.

6. Timelines and acceptance

Estimates of duration are made in good faith but are not guarantees. A deliverable is deemed accepted when you confirm it in writing, or seven (7) business days after we present it without written feedback listing material defects. We fix material defects in delivered work free of charge for 30 days after acceptance.

7. Intellectual property

Upon full payment of all fees for an engagement, we assign to you all intellectual property rights in the bespoke deliverables we create specifically for you. Until then, we retain those rights.

We retain ownership of:

• our pre-existing materials, internal tooling, templates and scaffolding;
• general know-how, methods and architectural patterns, which we may reuse on other projects;
• third-party and open-source components, which remain governed by their own licences (see section 9).

You grant us a licence to use your name and logo as a client reference only with your prior written consent, which may be withdrawn at any time.

8. Confidentiality

Each party will keep the other's non-public information confidential, use it only to perform the engagement, and protect it with at least reasonable care. These obligations do not apply to information that is public, independently developed, or required to be disclosed by law (in which case we will notify you where legally permitted). A mutual NDA is available on request and can be signed before any technical discussion.

9. Third-party services and open source

Deliverables may depend on third-party providers (for example cloud hosts, databases, payment processors, AI APIs, app stores). We are not responsible for their availability, pricing changes, policy changes or acts. We flag dependencies and their licence implications in writing, and we do not knowingly introduce copyleft licences into proprietary code without your approval.

10. Warranties and disclaimers

We warrant that services will be performed in a professional and workmanlike manner by suitably skilled personnel. Except as expressly stated in these Terms or an SOW, deliverables and this website are provided "as is" without further warranties, express or implied, including fitness for a particular purpose. We do not warrant uninterrupted or error-free operation of any system, and we do not provide legal, tax or accounting advice.

11. Limitation of liability

To the maximum extent permitted by law, neither party is liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, revenue, data or goodwill. Our total aggregate liability arising out of or relating to an engagement is limited to the total fees actually paid by you to us in the twelve (12) months preceding the event giving rise to the claim.

Nothing in these Terms limits liability that cannot lawfully be limited, including liability for wilful misconduct, or our obligation to keep your confidential information confidential.

12. Indemnity

You will indemnify us against third-party claims arising from content, data or materials you provide, from your instructions that we follow, or from your breach of section 5. We will indemnify you against third-party claims that our original work infringes their intellectual property, provided you notify us promptly and give us control of the defence.

13. Term and termination

Either party may terminate an engagement for material breach that remains uncured for 15 days after written notice, or immediately on insolvency. Retainers may be terminated by either party with 30 days' written notice.

On termination you pay for work performed and non-cancellable commitments up to the termination date, and we hand over completed deliverables, source code and documentation for which payment has been received. We will support a reasonable transition for up to 30 days at our standard rate if requested.

14. Force majeure

Neither party is liable for delay or failure caused by events beyond its reasonable control, including natural disasters, war, epidemic, government action, network or utility failures, or third-party service outages. Deadlines are extended by the duration of the event.

15. Non-solicitation

During an engagement and for 12 months afterwards, you will not knowingly hire our subcontractors or team members who worked on your project, without our written consent. General public job advertisements are excluded.

16. Governing law and disputes

These Terms are governed by the laws of Bangladesh. Before starting proceedings, the parties will attempt in good faith to resolve any dispute through senior-level discussion within 30 days of written notice. If unresolved, disputes are subject to the exclusive jurisdiction of the courts of Rangamati, Bangladesh. For engagements where the client requires it, we can agree in an SOW to a neutral governing law (for example English law) and arbitration seat.

17. Changes to these terms

We may update these Terms for the website and future engagements. The "Last updated" date above always reflects the current version. Terms agreed in a signed MSA or SOW are not changed by updates to this page.
