Develop Backend for AI web application (MVP) based on parallel.ai

Budget: 125000 UAH Deadline: 35 days

Hello. I have reviewed the project description and materials — the task is clear from both a technical and product perspective. I have practical experience in developing backend for AI-oriented SaaS solutions with asynchronous data processing, integrations with external AI / LLM APIs, rate limit control, queues, and fault tolerance.

I have worked with data enrichment and validation systems, where key aspects include parallel queries, stability of AI pipelines, and real-time processing of large tabular arrays. I have a good understanding of the architecture of hydration modules, validation logic, and lookalike search based on AI scoring or vector comparisons. I have implemented backend in Python (FastAPI), PostgreSQL, and Redis with clear load control and scaling.

I see the integration with parallel.ai as a separate service layer with queue management, retry logic, backoff mechanisms, and execution monitoring. I am ready to quickly engage in the project, work with the provided specifications, UI, and video overview, and bring the MVP to a stable working state.

I am ready to discuss the architecture, propose optimizations, and start working after agreeing on the details.

Good day, 15 years in development, recently actively worked with artificial intelligence and machine learning, would gladly take on your project.

Budget: 123456 UAH Deadline: 30 days

Hello!

I have significant experience in backend development for AI platforms. I recently completed a project where I integrated machine learning algorithms for processing large volumes of data using FastAPI and PostgreSQL, which greatly improved performance.

I will create the backend for your AI SaaS platform, focusing on deep integration with parallel.ai, stable management of request queues, and fast data processing. I will use FastAPI for asynchronous request handling and Redis for queue management, which will achieve high performance for the messenger.

I am ready to discuss the details and your needs, including the cost, which will vary depending on the scope of functionality. I look forward to your response!

Hello, I am a Golang developer with experience in developing high-load applications. This includes experience in developing a commercial product that processed large data through the ChatGPT API (automatic mapping of product categories). I will develop a reliable and maintainable service. Additionally, I have 8 years of experience as a business analyst/architect, so I quickly solve problems by finding solutions for complex tasks. The rate is $30 per hour. I cannot currently estimate the cost and timeline for the entire project; this requires a Discovery phase that will take about 16 hours. As a result, we will obtain a detailed architecture and an estimate for each feature.

I will create a backend core for your AI SaaS: a stable architecture for Smart Sheets, queue/limit management for parallel AI, pipeline state control, reproducible results with logging and retries.

Approach/Stack
Python + FastAPI (or Django if needed), PostgreSQL, Redis (queues), async I/O, integration layer for parallel AI (rate-limit, retry/backoff, idempotency), OpenAPI/Swagger, Docker environment.

Scope of Work

Domain architecture: projects/tables/rows/jobs/statuses, action auditing.
Hydration: batches, parallel requests, limit control, retries, progress/metrics.
Validation: rules/schemas, deduplication, normalization, error reporting.
Lookalike: scoring/vector search (if needed pgvector/separate service), API for searching and ranking.
Admin/service endpoints, access tokens, roles, logging, tracing, test cases.

Questions

1. What authentication is needed: email+password, SSO, or only workspace/token?
2. Smart Sheets: custom table model or integration with Airtable/Google Sheets?
3. Progress in front: webhooks/streaming or is polling API sufficient?

Result
Ready backend MVP: API, queues, database, integration with parallel AI, OpenAPI documentation, launch and deployment instructions.

Cost: 320,000–520,000 UAH or 900–2,200 UAH/hour. Expand

Hello! I specialize in developing high-load Backend systems in Python (FastAPI). I have real experience working with Big Data: I successfully implemented parsing and structuring of tables with over 40,000 rows and a large number of columns.

Architecture and Docker: My project CargoBot is fully containerized (Docker Compose), which ensures stable operation and easy scaling.

Working with APIs: I understand the logic of building queues (Redis) for managing limits of Parallel.ai and processing parallel requests (asynchronous programming).

Data Processing: I have skills in reverse engineering and validation of complex data, which is critical for the Hydration and Lookalike modules.

All details, technical stack, and successful cases are in my profile. I am ready to study the specification in Axure and start working.

Hello. I have been working with Node.js for over 8 years. I am ready for collaboration.

Budget: 125000 UAH Deadline: 30 days

Hello.
I have reviewed the platform description, and the task seems completely realistic, but with a non-trivial architectural component — this is what intrigued me.

I specialize in backend architecture and integration of complex external APIs (AI / data pipelines / asynchronous queues). In similar projects, I consider the key to success not so much the AI challenges themselves, but the orchestration of tasks, stability, limit control, and processing large arrays of tabular data.

How I see the implementation of key modules

Hydration (Data Enrichment)
It makes sense to build the central module through queues and workers (Redis), with batch processing of table rows and managing the parallelism of calls with parallel.ai.
Mandatory components: rate limiting, retries with backoff, idempotency of tasks, and preserving provenance (which agent/pipeline filled the field).

Validation
A separate pipeline for enrichment: structural rules, deduplication (exact + fuzzy), normalization of formats, and quality scoring. This significantly reduces cost and noise at the AI-hydration stage.

Lookalike
Finding similar objects is possible through scoring or vector comparisons (embeddings) — depending on where the database is stored (internal or via parallel.ai). The optimal approach is staged: fast-filter → AI-rerank.

Technical Stack

I work with both Python (FastAPI) and Node.js (NestJS/Fastify).
For this project, I see an asynchronous architecture with PostgreSQL (main data) + Redis (queues, throttling, task states) as optimal.

Experience

I have experience in:
building backend cores for SaaS products
working with large tabular data
integrating AI APIs with limits and parallel requests
designing queues, workers, and fault-tolerant processing

Cost and Format

The estimate depends on:
the volume of v1 (number of columns, types of hydration, validation rules)
expected processing speed of tables
depth of the lookalike module

Approximately: from $8500 to $12000 for the MVP core, with phased implementation and scalability options.

The selling price is approximately $12,000 - $25,000

I am ready to evaluate in more detail after reviewing the specifications and UI.
I would be happy to discuss the architecture, constraints, and the first stage of implementation.

Best regards,
Ruslan Expand
