Fintech platform for P2P exchanges of digital assets - team search

Budget: 27000 UAH Deadline: 60 days

Good day,

I am sure that we can help you. Just recently we worked with a crypto project, a SAAS platform for working with an auto-trade bot:
(I started looking for a link to the platform, but apparently something did not work out for them after 3-4 years since our work, all that remains is https://jobs.dou.ua/companies/cupo/)

You can review our portfolio on our corporate website:

Our rate is 25/hour, estimating the approximate cost without a technical specification is very difficult. Can we take a look? The same applies to deadlines. We can start almost immediately after all approvals.

We hope for further cooperation.
Sincerely,
The SpaceLab Team Expand

Good day!

I read the description — the task is within our area of expertise. A team of 6 people, we have relevant experience with financial integrations, Stripe Connect, multi-tenant architecture, and Telegram bots. We fully cover the stack of NestJS + Next.js + PostgreSQL + Redis + BullMQ.

Relevant experience: SaaS platforms with Stripe Connect and direct payouts, billing with recurring payments and handling failed charges, enterprise projects with CRM integrations, Telegram bots with queues. Under NDA, fintech projects with payment gateway integrations and multi-vendor payouts. We will show code and architecture in private.

Regarding technical patterns, we have real practice:

Idempotency through keys in the database with UNIQUE constraint, so that repeated webhooks do not create duplicates
Distributed transactions through the outbox pattern with BullMQ for reliable processing of financial events
Rate limiting at the Redis level with sliding window
Encryption of sensitive data through HashiCorp Vault or KMS
Webhook reliability with retry logic and idempotent processing

We regularly use the stack Prisma, shadcn/ui, grammY, Docker, GitHub Actions.

In terms of format, we are ready to work iteratively in 9 stages with a demo after each. We have experience working under strict acceptance criteria.

Regarding timelines and costs, we will provide an accurate estimate after getting acquainted with the detailed technical specification. An MVP volume of 8-10 weeks is realistic for a team of our format.

We are ready to start immediately after agreement.

Best regards,
Dmitry Expand
