What technical leaders say
“Smartbrain’s Django squad delivered a PCI-compliant billing engine in six weeks. They integrated cleanly with our GitLab CI, wrote unit tests, and documented every endpoint. Our internal devs regained velocity instead of rewriting invoices.”
Melissa Carter
CTO
BlueWave Payments
“The augmented FastAPI engineers solved OAuth headaches and timesheet imports. We hired on Tuesday; by Friday staging showed green checks. Productivity rose 32 % and finance finally trusts the data.”
Jacob Hernandez
Director of Engineering
LogiTrack Logistics
“Their Pandas specialists automated 1099 reports and multi-currency payouts. Compliance risk dropped to zero; accounting closes now take half the time. Integration with our Snowflake lake was flawless.”
Whitney Lee
VP Finance Systems
MedVerge Health
“Async Python tasks replaced brittle cron jobs, slashing AWS costs 27 %. Smartbrain’s vetting was thorough—every developer could explain SOLID and DDD. Onboarding took a single Zoom call.”
Robert Kim
Backend Lead
StreamJoy Media
“Their Flask experts rebuilt our invoice API with zero downtime. We met SOC 2 audit, improved throughput 3×, and HR loves the new self-service onboarding portal.”
Angela Moore
Chief Product Officer
GreenLeaf Energy
“Smartbrain plugged two senior Pythonistas into our Kanban board. They refactored legacy Celery queues and improved test coverage to 92 %. Delivery schedules are now predictable.”

Industries we optimise
FinTech Automation
FinTech firms need razor-accurate ledger updates, multi-currency invoicing, and KYC workflows. Augmented Python engineers craft contractor onboarding billing engine modules with Pandas, Django, and Stripe APIs to match SEC and PCI standards while keeping time-to-market low.
E-commerce Platforms
Retail marketplaces juggle thousands of sellers. Our Python devs build scalable onboarding forms, tax calculation microservices, and real-time payout dashboards, optimising the billing engine using FastAPI & Redis for holiday-proof performance.
Healthcare Compliance
HIPAA-driven providers rely on accurate contractor credentialing before claims. Python bots validate NPI & CPT codes, while the contractor onboarding billing engine encrypts PHI via PyNaCl, ensuring audit trails that pass OCR inspections.
Logistics & Supply Chain
3PL operators pay hundreds of drivers weekly. Python augmented teams stitch GPS, ELD, and timesheet data into a billing engine that releases ACH files automatically, cutting reconciliation hours by 70 %.
Media Streaming
OTT platforms pay creators per view. Python microservices ingest Kafka streams and feed a revenue-share contractor onboarding billing engine that closes financials daily, preventing royalty disputes.
EdTech SaaS
Course marketplaces must handle tutor onboarding, tax forms, and milestone payments. Django Rest Framework helps our augmented devs expose secure endpoints the billing engine consumes, driving tutor satisfaction scores up.
Energy & Utilities
Field contractors submit work orders from rigs. Python Lambdas normalise data while a robust billing engine issues invoices to SAP, keeping Sarbanes-Oxley auditors happy.
MarTech Analytics
Agencies onboard freelance designers constantly. Our Flask-based contractor onboarding ensures NDAs are signed, then auto-creates billing schedules in HubSpot, reducing manual spreadsheet work.
IoT Manufacturing
Smart-factory vendors integrate sensor-driven job tickets with a Python-powered contractor onboarding billing engine that matches part numbers to service invoices in real time.
Contractor Onboarding Billing Engine Case Studies
FinPay Scale-Up
Client: Series-B FinTech platform
Challenge: Their contractor onboarding billing engine stalled under 10 k daily invoices.
Solution: Two Smartbrain senior Python engineers refactored legacy Django ORM calls, introduced async endpoints with FastAPI, and deployed a Redis-backed queue to batch financial events. They worked side-by-side with the client’s Scrum team, attending stand-ups remotely and pushing code through existing CI/CD.
Result: 83 % throughput increase, nightly reconciliation time dropped from 3 h to 20 min, and finance closed month-end three days faster.
HealthSync Compliance Push
Client: Nationwide telehealth provider
Challenge: A new state regulation mandated real-time credential checks inside the contractor onboarding billing engine.
Solution: Our augmented Python squad integrated FHIR endpoints, built a Celery task pool for background verifications, and added cryptographic audit logs. Collaboration happened via Slack, Jira, and pair-programming sessions.
Result: 0 compliance violations during the first audit and a 47 % reduction in manual credential review hours.
SupplyChain Rapid Rollout
Client: Fortune-100 logistics enterprise
Challenge: M&A doubled driver count; the existing contractor onboarding billing engine couldn’t ingest disparate timesheet formats.
Solution: Three Pandas specialists created a schema-agnostic parser, while a Flask API exposed unified endpoints to the SAP backend. Go-live completed in eight weeks with zero downtime.
Result: 2.4 × faster onboarding and $1.8 M annual savings from eliminated rework.

Services we deliver
API Development
Design and build REST/GraphQL endpoints that power your contractor onboarding billing engine, enabling seamless data exchange with ERPs and payment gateways. Faster integration, lower friction.
Data Pipelines
ETL & analytics implementations in Python/Pandas turn raw timesheets into clean, payable records, boosting finance accuracy while freeing your BI team.
Compliance Automation
Automate KYC/AML checks with Python bots that run background verifications and inject the results into the billing engine, minimising legal risk.
Performance Optimisation
Refactor slow queries, add async patterns, and introduce caching to ensure your contractor onboarding billing engine scales on peak days without costly infra spikes.
