Frequently Asked Questions

What Python services do you provide?
Everything in Python: custom APIs & backends (FastAPI/Django/Flask), multi-tenant SaaS, data engineering & ETL, automation and scripting, integrations (payments, ERP, maps, broker APIs), ML/AI integration, performance & security hardening, audits, migrations, and long-term maintenance. We cover greenfield builds and full rescue/modernization of legacy apps.
Why choose PRECISION for Python work?
30 years of shipping production systems. Strong architecture and clean code with disciplined Git and CI/CD, observability, and SLAs. We are comfortable inheriting complex, messy stacks and making them stable, fast, and secure without disrupting business.
Do you support both custom Python and open-source platforms?
Yes. Custom Python with or without frameworks, plus Django/Wagtail CMS, Odoo (ERP), Saleor, Plone, and headless CMS patterns backed by Python APIs.
Do you offer a prepaid Python support block?
Yes. A convenient starter is 6 hours of Python programming support for ₹9,900. It covers bug fixes, enhancements, audits, and consults. You can stack blocks or move to a retainer or a dedicated team.
What engagement models do you offer?
Fixed-scope projects, time-and-materials (hourly/blocks), monthly retainers, and dedicated developer pods. We align with your release cadence, compliance, and budgeting.
How do you onboard an existing Python codebase?
A fast health check: repository review, environment parity, dependency and infra map, security/performance checklist, and a prioritized remediation plan. Then we deliver fixes in small, low-risk increments.
Do you provide on-site Python developers?
Remote-first worldwide with optional on-site for discovery, launches, and reviews. We can embed a developer on premises for short sprints.
Can you take over an existing Python project from another vendor?
Yes. We routinely inherit projects. We stabilize production first, then modernize safely without breaking users.
Which Python versions and frameworks do you support?
Python 3.x across FastAPI (ASGI), Django (WSGI/ASGI), Flask, Starlette, and microservices. Frontends (React/Vue/Tailwind) often pair with Python APIs.
Do you build REST/GraphQL APIs with Python?
Yes. Versioned endpoints with pagination/filtering, auth (JWT/OAuth2), rate limiting, idempotency, request signing, webhooks, and full audit logs and metrics.
Can you integrate payments, email, maps, and other third-party APIs?
Razorpay/PayU/Stripe, WhatsApp Business API, Gmail/Calendar, Maps & GPS (Google/OSRM), Tally/IRP for GST e-invoicing, SMS gateways, Zerodha Kite, shipping, KYC/OTP, and more.
How do you approach Python performance at scale?
ASGI/WSGI tuning (uvicorn/gunicorn), asyncio where appropriate, query/index optimization, object & HTTP caching (Redis), CDN, async queues, profiling, and performance budgets enforced in CI.
Do you handle queues, jobs, and real-time features?
Yes. Celery/RQ/Dramatiq, scheduled jobs (Celery Beat/Airflow/Prefect), supervised workers (systemd/Supervisor). Real-time with WebSockets/SSE, background tasks, and message brokers.
What databases and storage do you support with Python?
PostgreSQL/MySQL, SQLite for edge, Redis for caching/queues, and optional document stores where they fit. We manage migrations, rollbacks, data-fix scripts, and safe schema changes.
Do you build multi-tenant SaaS in Python?
Yes. Tenant isolation (schema/row), per-tenant configs, rate limits, subscription/billing hooks, webhooks, audit trails, and secure file storage strategies.
Which servers, operating systems, panels, and clouds do you support for Python?
Servers: Nginx/Apache + Gunicorn/uWSGI/uvicorn; optional Caddy/HAProxy. OS: AlmaLinux/Rocky, Ubuntu, Debian, Windows (IIS/Reverse proxy) when required. Panels: Plesk, cPanel/WHM, DirectAdmin, Virtualmin/Webmin, CyberPanel, RunCloud. Clouds: AWS, GCP, Azure, and on-prem. Edge/CDN via Cloudflare and others.
Do you work with Docker and orchestration?
Yes. Docker/Podman images, compose stacks, CI builds, secrets, health checks, and Kubernetes where it makes sense. We also support classic Nginx/Apache deployments without containers.
What deployment patterns do you recommend for Python?
ASGI/WSGI apps behind Nginx, systemd-managed processes, zero-downtime deploys, blue-green/canary, environment parity with .env/secret managers, and infrastructure as code where feasible.
How do you secure Python applications?
OWASP Top 10 controls, strict input validation/output encoding, parameterized queries/ORM safety, CSRF tokens (where relevant), robust session settings, password hashing (Argon2id/BCrypt), file-upload safelists and scanning, CSP/HSTS, secrets management, least-privilege infra, and continuous dependency checks (pip-audit, safety).
Do you help with compliance (DPDP, GDPR, PCI, HIPAA-like)?
Yes. Data minimization, consent logs, purpose tags, encryption at rest/in transit, keyed hashing for identifiers, retention and deletion workflows, DLP and access logging. PCI guidance for payment flows and PII governance playbooks.
How do you handle email deliverability from Python?
Python smtplib/Django/Framework backends over SMTPS (465), correct SPF/DKIM/DMARC with alignment, bounce/complaint processing at higher volumes, and inbox tests with Gmail/Outlook to confirm pass results.
Do you build and harden Django/Wagtail sites with Python?
Yes. Custom apps, CMS features, performance fixes, caching, secure uploads/admin, safe update pipelines, and Python 3.x migrations. We modernize legacy JS glue while keeping templates tidy.
Can you extend Odoo or build commerce backends in Python?
Yes. Odoo customizations and connectors; commerce with Saleor or bespoke FastAPI/Django backends, payment/shipping flows, and ERP integrations—while keeping upgrades safe via proper extension points.
Can you upgrade old Python 2/early 3 code to current Python 3.x?
Yes. We catalog breaking changes, replace deprecated libs, add tests around risky areas, introduce typing where pragmatic (mypy), and roll out safely with feature flags and staged deploys.
Do you refactor legacy monoliths?
We stabilize first. Then we modularize domains, add interfaces and boundaries, and only split to services if it clearly reduces risk and unlocks velocity.
Can you migrate to or from Python?
Yes. We migrate Node/.NET/Rails to Python when it fits your team and infra, and we also migrate Python workloads out where business needs demand another stack. The plan is data-first with measurable cut-over steps.
Do you write tests and enforce code quality?
pytest for unit/feature tests, API contract tests, smoke tests for critical flows, static analysis/typing with mypy, linters/formatters (ruff/flake8, black, isort), and pre-commit checks in CI.
What observability do you set up?
Structured logs (JSON/structlog), request IDs and correlation, metrics/APM (OpenTelemetry/Prometheus/Grafana), log shipping (ELK/Opensearch), alerting, and error tracking with actionable runbooks.
Who owns the code you develop?
For custom projects, you own the code and IP as per contract. Our reusable internal libraries remain ours. For our products, you receive licenses with clear usage rights. We comply with OSS licenses when using open-source.
Can you work under NDA and with our Git provider?
Yes. NDA is standard. We use GitHub/GitLab/Bitbucket with protected branches, PR reviews, required checks, and signed commits if needed.
Do you support SEO, PWA, and accessibility for Python sites?
Yes. Server-rendered pages (Django templates/Jinja2) with clean URLs, schema.org JSON-LD, Core Web Vitals budgets, sitemaps/robots, and service-worker PWAs where useful—all without sacrificing backend maintainability and security.
What response times do you offer?
Business-hours response with emergency channels; faster SLAs are available on retainers. We work in IST and can extend overlap for global teams.
Can you start a discovery workshop this week?
Often yes. We can kick off remotely and schedule on-site sessions for stakeholders and engineering.
Our Python app or API is down. Can you help urgently?
Yes. Emergency stabilization: log capture, rollback, hotfix, and a short remediation plan to prevent repeats.
