Software engineering services by Cevrynt: Senior engineers who build, fix and ship.

Dedicated developers, fixed-scope builds and rescues, Stripe payments and lending-ops automation for startups, agencies and lenders in the US, UK and EU. A written scope and price before any work is billed.

01Why teams come to us

Four problems bring teams to us. Each has one engagement.

Read down the four. If yours is here, the engagement is already chosen and its terms are set out below. If it is not, say so on the call and we will tell you plainly whether we can help.

Intake · 01 / 04The problem, in your words

“Hiring senior developers takes months, and agencies need capacity that can start this month and stop when the project does.”

What it looks like

  • Senior hires take months
  • Capacity needed this month
  • Should stop when the project does
FitsDedicated EngineersYou are buying capacityFrom $4,000/month per engineer

02Choose your engagement

Start from the problem. The engagement follows.

Four ways to work with us, each built for one situation. Each one sets out the terms buyers actually compare: who runs the backlog, how it is billed, when it starts and how it ends. Every engagement begins with a written scope and price.

03Is this for you

Say who you are. The route to the right engagement draws itself.

Pick the line that is you. Each one routes to the engagement built for it, to the product, or to a call where we say plainly whether we can help. Then read what these services are not.

04What we build

Six kinds of work. Each one shipped in your name.

Everything an engagement delivers is one of these six. Each names what it is, where a client has seen it, and the engagements it usually runs under. Pick an engagement to see which apply.

06How an engagement runs

Every step ends with something you can hold.

Five steps, the same for every engagement. None of them ends in a status update: each one ends in a document, a link or a working system in your name, so you always know where the work stands and what it will cost.

  1. Step 01 of 05

    Discovery

    A call to understand the product, the users and what has to be true at launch.

    You receive
    • A plain answer on whether it is a fit, or not
    • The questions we would need answered before scoping
    • A suggested engagement, if one fits
  2. Step 02 of 05

    Fixed scope

    A written scope with the work, the price and the timeline before anything is billed.

    You receive
    • The work, listed line by line
    • A fixed price, in writing
    • A dated timeline, and nothing billed before you sign
  3. Step 03 of 05

    Weekly demos

    Working software every week, on a staging link you can click through.

    You receive
    • A staging link that is updated every week
    • A demo in your hours, where they overlap
    • A short note on what changed and what is next
  4. Step 04 of 05

    Launch

    We deploy to your infrastructure, with handover notes and access in your name.

    You receive
    • A deployment on infrastructure you own
    • Repositories, accounts and documentation in your organisation
    • A repeatable release process
  5. Step 05 of 05

    Support

    We stay on for fixes and small changes, by the month or as needed.

    You receive
    • Fixes and small changes after launch
    • By the month, or as needed
    • Scale down or stop with notice
→The lowest-risk way in

Not ready to commit to a build? Start with the Technical Audit.

$1,500, delivered in 5 business days. You get a code, security and deployment review and a written plan with a fixed price for the fixes, whether or not we do them.

  • Code and architecture review
  • Security and data-handling issues, ranked by risk
  • Deployment and hosting review
  • A written plan with a fixed price for the fixes

07What drives the price

No price is a surprise. Here is what moves each one.

Four engagements, four ways of pricing. For each: what you pay for, where it starts, what moves it, and the point at which it is agreed in writing. The same four rules hold across all of them.

  • 01Scope firstA written scope with the work, the price and the timeline before anything is billed.
  • 02Nothing before signatureNothing is billed before you sign.
  • 03In writing, per engagementEvery price is agreed in writing for that engagement.
  • 04Support as neededAfter launch, support is by the month or as needed.

08Who you work with

Five people. Senior, remote from India, in your hours.

You work directly with Arindam Pradhan, who has built production software since 2018, and four senior engineers with six or more years each. We work remotely from India with overlap into US and European hours. Before Cevrynt, the same team delivered client work as GreenBorn Infotech.

09Clients and work

The teams we have built for, and what we built.

Ten companies that have agreed to be named, three builds set out as problem, system and stack, and two project videos. No invented results: where a client has not confirmed a figure, none is shown.

Problem
Megapos, a point-of-sale company, needed in-person card payments inside a kiosk app whose interface is a web app, while Stripe Terminal Tap to Pay runs natively on the device.
What we built
A Flutter WebView kiosk with a Node/Express backend and a native Kotlin bridge to Stripe Terminal Tap to Pay. The PaymentIntent and its client secret pass securely from the web layer to Flutter to Kotlin, so the payment is collected natively without exposing keys in the web app.

9Questions, short answer first

2Answered with a plain yes or no

1Answer that states a price

01What does it cost?From $4,000 a month

Dedicated engineers start from $4,000 a month per engineer. The Technical Audit is $1,500, delivered in five business days, and a Production Sprint starts from $6,000. Stripe work and lending-ops automation are scoped after an audit or a walkthrough. Every price is agreed in writing before any work is billed.

02How quickly can someone start?Usually within the month

Dedicated engineers can usually start within the month, subject to availability; we tell you who is free and when on the first call. A Technical Audit starts as soon as we have the repository and is back with you in five business days.

03Who actually writes the code?The people you meet

The people you meet. You work directly with Arindam Pradhan and senior engineers with six or more years each. We are a small team, so there is no hand-off to juniors after the sale.

04Where are you, and will our hours overlap?India, on US and EU hours

We work remotely from India and shift our day to overlap with US and European hours. Weekly demos happen in your hours, where they overlap, and you get a staging link you can click through at any time.

05Who owns the code and the accounts?You do, from day one

You do, from day one. Repositories, accounts and documentation sit in your organisation, and at launch we deploy to infrastructure you own and hand over notes and access in your name.

06Can you work under our agency’s name?Yes

Yes. White-label is available for agencies: we work under your name, and your client never needs to know we exist.

07What happens if we want to stop?Stop with notice

Monthly engagements scale up, down or stop with notice; there is no long contract. Fixed-scope work ends at launch, and support after that is by the month or as needed.

08Are you a Stripe partner?Yes

Yes. Cevrynt, Inc. is a Stripe partner in the Stripe Partner Ecosystem, with a public profile in the Stripe Partner Directory. Three members of the team also hold individual Stripe professional certifications: Arindam Pradhan as a Stripe Certified Professional Implementation Architect, and Anupam Pradhan and Subhadip Giri as Stripe Certified Professional Payments Architects.

09We are a lender. Is this the right page?Depends what you need

If you need automation on top of the CRM and tools you already run, yes: that is the lending-ops automation service. If you need a full underwriting review of borrower files, that is Cevrynt’s underwriting platform, which is a product rather than a service.

Short answers never say more than the full ones; they only say it first. Prices are agreed in writing before any work is billed.

Ask yours on a call

11For lenders

Need underwriting rather than automation? That is the product.

Lending-ops automation builds on the CRM and tools you already run. Cevrynt’s underwriting platform is a different thing: it turns borrower documents and business signals into evidence-linked analysis for your human underwriters, and the final decision stays with you.
