Growth Quantix
Algorithmic trading infrastructure: multi-broker feed ingestion, Redis Pub/Sub event bus, and single-authority exit risk controls.
4+ Years in Production
Backend Software Engineer at ArisGlobal, building Spring Boot microservices for global pharmaceutical workflows since Oct 2021.
Published Open Source
upstox-auth-pro is a live PyPI package I built and maintain — not a toy project, a shipped SDK with real users.
I Write Up My Architecture
Every non-trivial system I've built has a public case study with diagrams — see for yourself how I think before you hire me.
What I Can Build For You
Four areas I take freelance work in — each grounded in something I've already shipped, not just a skill I'm listing.
Backend API & Microservice Development
Java/Spring Boot or Python/FastAPI backends: REST APIs, database schema design, third-party integrations, and clean service boundaries.
Real-Time & Data Pipeline Systems
WebSocket/streaming ingestion, Redis Pub/Sub or Kafka-based event buses, and dashboards that need live data without falling over under load.
Automation, SDKs & Scripting Tools
OAuth/login automation, internal tooling, scrapers, CLI utilities, and packaged SDKs — the kind of thing that turns a manual process into a script.
AI-Assisted System Integration
Wiring an LLM or ML model into a real backend — with deterministic guardrails, risk filters, and validation, not just a raw API call in production.
How I Work
Step 1
Discovery
A short call or written brief to understand what you need, whether it's a good fit, and roughly what it'll take.
Step 2
Scope & Proposal
A written scope with milestones and an honest timeline — given this is part-time work, I'd rather under-promise than miss a date.
Step 3
Build & Check-Ins
Async progress updates at each milestone instead of long status meetings. You see working code, not just status reports.
Step 4
Handoff & Support
Documentation, deployment help, and a short post-launch window to fix anything that comes up.
Proof of Work
Real systems, not tutorials. Each one has a full architecture write-up.
Upstox Auth Pro
Published Python SDK automating OAuth2 login and TOTP 2FA with Playwright — shipped, versioned, and installed via pip.
Prindox
Document processing platform: upload/order REST APIs and async validation backed by an optimized PostgreSQL schema.
Engagement & Pricing
I don't publish fixed rates — every project is different, and this is part-time work fit around a full-time job, so I quote based on scope, not a rate card. Tell me what you need built and roughly what you'd like to spend, and I'll tell you honestly whether it's something I can take on and what it would cost.
Best fit: well-scoped backend, pipeline, or automation projects that can be delivered in defined milestones — not open-ended retainers or projects needing daytime availability.
Frequently Asked
Are you full-time available?
No — I work full-time at ArisGlobal. Freelance work happens evenings/weekends, so I take a limited number of projects and I'm upfront about timelines before we start.
What's a typical project size?
Small-to-medium, well-defined scopes work best — a backend service, an integration, an automation script — rather than open-ended full-product builds.
Do you sign NDAs?
Yes, happy to sign an NDA before discussing project specifics.
How do we get started?
Email me a short brief — what you need, rough timeline, and budget range — and I'll reply with whether it's a fit and next steps.
