Rushikesh Hulage · Software Engineer, Telstra
I work on customer identity at Telstra — and ship AI systems to production.
I'm a backend engineer on Telstra's customer identity (CIAM) platform, working on the Java/Spring Boot services behind login, registration, MFA and account recovery — OAuth 2.0/OIDC, mTLS and edge WAF on AWS. Outside work I build applied-AI systems: Atlas, VisionTrack and Finertia, all live.
- Part of 15+ app migrations · zero auth downtime
- mTLS cert rotation automated

Selected Work
A catalog of systems
Applied-AI and systems work I've taken from design to production — retrieval/RAG platforms, a real-time computer-vision SDK, and a quantitative backtesting SaaS.
VisionTrack — Real-Time Multi-Object Tracker & SDK
A real-time multi-object tracking engine built from first principles — Kalman filter, Hungarian assignment, and ByteTrack association — shipped as a published PyPI SDK.
Finertia — Momentum Backtesting SaaS
A momentum-strategy backtesting platform with a pure pandas/numpy engine (no backtesting libraries), a React front end, and a cost-capped Cloud Run backend. Live.
Sextant — MCP-Native RAG
An MCP-native retrieval-augmented generation system with cost-aware experiments, table-aware chunking, and query decomposition. Open source (MIT).

Where I've worked
The roles where I've built and secured scalable platforms — most recent first.
Software Engineer – Identity & Platform Engineering
Telstra · Pune, India- Build and maintain Java/Spring Boot services on Telstra's customer identity (CIAM) platform — registration, authentication and authorization flows using OAuth 2.0/OIDC, JWT/JWKS validation, token introspection and exchange, session management, MFA and RBAC.
- Part of the team that migrated 15+ enterprise applications from PCF to OpenShift with zero authentication downtime — rebuilding auth integration, secure routing and IP allow-listing ahead of each cutover.
- Worked on end-to-end mTLS with automated X.509 issuance and rotation, removing manual certificate renewal as a recurring outage risk, and on TLS termination at the CDN edge.
- Worked on the edge migration from legacy WAF to AWS CloudFront + WAFv2 — OWASP-aligned rule groups, regex pattern sets, IP reputation lists and rate-based rules — with a phased, zero-downtime DNS cutover across 10+ downstream apps.
- Configured OIDC/OAuth 2.0 clients in PingFederate and SecureAuth for SSO and single logout across enterprise apps, including federation with Salesforce and Entra ID.
- Contributed to platform modernization — Java/Spring Boot upgrades, dependency and vulnerability remediation, and CI/CD automation.

About
Customer identity at Telstra. Applied AI in production.
At TelstraI'm a backend engineer on the customer identity (CIAM) platform — Java & Spring Boot services for login, registration, MFA and recovery, built on OAuth 2.0/OIDC, JWT/JWKS and RBAC, with PKI, mTLS and TLS termination underneath.
I was part of the 15+ app PCF→OpenShift migration with zero authentication downtime, and worked on the AWS CloudFront & WAFv2 edge migration across 10+ downstream apps and on automated X.509 certificate rotation that took manual cert renewal off the outage risk list.
Outside work, I build applied-AI systems: agentic RAG (Atlas), real-time computer vision (VisionTrack), and quantitative backtesting (Finertia). A B.Tech graduate from VJTI Mumbai, I contribute to Hugging Face Transformers and placed Top 10 at the Google APAC Challenge 2025.
