Senior Software Engineer@UBI | Ex-Cisco

About

I build backend systems that stay up when things get hard. Currently Senior Software Engineer II at UsefulBI, where I architected the backend for an AI-powered clinical document platform on FastAPI + PostgreSQL — designed for FDA 21 CFR Part 11 compliance from day one, with audit trails, section-level versioning, and RBAC across 12+ modules. Most recent measurable win: I cut clinical document retrieval from 7–8 seconds to under 50ms — a 99.3% reduction — by replacing synchronous S3 polling with a database registry and turning O(n) prefix scans into O(1) indexed queries. Before UsefulBI, I spent five years at Cisco Systems building the platform automation that kept 200+ enterprise applications reliable: MySQL upgrades, Postgres provisioning, Oracle switchover, production-to-non-prod refresh workflows, MongoDB cluster operations, and a resilient switchover system using gRPC across primary/standby clusters. Along the way I cut SOX compliance reporting from 3+ hours to under 10 minutes, and reduced manual DBA workload across the org by 80%. I started as an intern and automated MySQL cluster upgrades from 1 hour to 10 minutes in the first six months. Recently I've been going deeper on LLM orchestration — designing automated report generation pipelines with AWS Step Functions and Bedrock, with Lambda handling each stage (ingestion, section-wise generation, validation, assembly) and domain SMEs collaborating on regulatory requirements. Stack I work with every day: • Languages — Python, JavaScript, TypeScript • Backend — FastAPI, Django, Flask, Express, gRPC • Data — PostgreSQL, MongoDB, MySQL, Oracle, Redis, Cassandra, Kafka • Cloud & infra — AWS (Bedrock, EKS, ECR, RDS, S3, Lambda, Step Functions), Docker, Kubernetes, Terraform, Ansible, Helm, Jenkins Certified: MongoDB DBA · AWS Certified Cloud Practitioner · HashiCorp Terraform Associate · PCAP — Python Programming. B.E. Computer Science, BMS College of Engineering (9.2 GPA). Focus areas: distributed systems, platform reliability, LLM infrastructure, GenAI backends. Based in Bengaluru (IST); comfortable across US and EU time overlap. 📩 prateekaryyan@gmail.com 🔗 github.com/prateekaryann 🌐 prateekaryann.github.io/portfolio

Work experience

Senior Software Engineer II at UsefulBI Corporation, Nov 2025 - Present · 10 mos, Bengaluru, Architecting the backend for an AI-powered clinical document platform on FastAPI + PostgreSQL. Most of my work is at the intersection of regulated industries, LLM orchestration, and platform reliability. • Designed FDA 21 CFR Part 11 compliance (audit trails, section-level document versioning, RBAC) across 12+ modules from day one. • Set up the team's first production-grade CI/CD pipeline — EKS, ECR, and automated Helm deployments — cutting deploy time from hours of manual work to under 15 minutes across dev and production. • Built a clinical study document management system with section-level versioning and multi-stage review-approval workflows, enabling regulatory teams to manage CSR, DSUR, and PLPS documents on one platform. • Optimized clinical document retrieval API from 7–8s to under 50ms (99.3% reduction) by replacing synchronous S3 polling with a database registry — O(n) prefix scans → O(1) indexed queries. • Designed an automated report generation pipeline using AWS Step Functions to orchestrate multi-step LLM workflows — ingestion, section-wise generation via AWS Bedrock, validation, and assembly — with Lambda per stage, collaborating with domain SMEs on regulatory requirements.

Software Engineer at Cisco, Nov 2023 - Nov 2025 · 2 yrs 1 mo, Bengaluru, Owned database platform automation for 200+ enterprise applications across Cisco's internal services. This role was SRE work in everything but the title on paper. • Automated MySQL upgrades, Postgres provisioning, Oracle switchover and patching, and production-to-non-prod data refresh workflows — reducing manual DBA workload across the org by 80%. • Built a resilient switchover automation system using gRPC for low-latency communication across primary and standby distributed clusters — ensuring system resiliency at scale. • Managed self-hosted MongoDB clusters for production workloads powering 100+ enterprise applications — backup/recovery, replication, and performance tuning. • Designed and implemented database provisioning workflows using Terraform, Flask, and Ansible — automating VM creation on OpenStack, instance configuration, and data refresh.

Software Engineer at Cisco, Aug 2021 - Nov 2023 · 2 yrs 4 mos, Bengaluru, Platform automation for database operations on Cisco's internal enterprise systems. Worked across the team that became the database SRE function. • Accelerated SOX compliance reporting from 3+ hours to under 10 minutes by building an automated reporting pipeline, analysing production features with analytics to measure operational impact. • Contributed to the gRPC-based switchover automation and MongoDB cluster operations that the senior role later extended. • Cut MySQL cluster upgrade automation from 1 hour to 10 minutes (originally built during the intern stint, extended in this role).
