About Abhijit Pal

I specialize in designing and scaling large-scale, cloud-native distributed systems with a strong focus on high availability, scalability, security, and operational excellence. Currently, I lead core backend and platform initiatives within Oracle Cloud Infrastructure (OCI).Current Impact at OracleOCI Bastion (Tier-0 Service): Architecting and building secure access services using Java, Spring Boot/Dropwizard, and Go, supporting internal operators and global enterprise customers with strict security and availability SLAs.Strategic AI / LLM POC: Worked on Python-based initiatives integrating LLMs (GPT-4.1, Cohere, Grok-4) with Autonomous Database (Property Graph) to enable advanced identity analytics and intelligent access management.Oracle Mobile App (OMA): Led the end-to-end development of a cross-platform solution using Flutter, Dart, and Java, which actively used by internal Oracle teams.Proven Industry ImpactTesco: Built high-throughput, event-driven microservices on Azure (Spring WebFlux), reducing payroll processing cycles from T+3 to T+1 days.Citi: Led platform modernization and automation initiatives, improving operational efficiency by ~60% and infrastructure efficiency by ~50%.Technical ExpertiseBackend & Systems: Java 17, Go, Python, Spring Boot 3, WebFlux, Microservices, Distributed Systems, System DesignCloud & DevOps: OCI, Azure, Docker, Kubernetes, Terraform (IaC), JenkinsData & Messaging: Oracle DB, Autonomous DB, Redis, MongoDB, Kafka (POC)I thrive on solving complex backend and platform engineering problems, driving engineering rigor through architecture reviews, system design, and mentoring.

Experience

   Oracle

   Apr 2024 — Present · Bengaluru, IN

   Project Bastion -1. Architected and built a Tier-0 secure access service (Java,Go,Python,Terraform,DropWizard), delivering ~45–50% of encrypted tunneling scope for Oracle operators and enterprise tenants.2. Enabled rollout across OCI regions and partnered on readiness/launch for OC1 (Phoenix, Mumbai) and OC47 (London).3. Fixed Tier-0 Session Recording reliability by handling LSE scenarios and eliminating session loss from missing Tier-0 resources and using Tier 1 bucket resources, improving continuity and auditability.4. Contributed to multi-region/global readiness; built Terraform IaC for region builds/provisioning, reducing manual ops.5. Technical multiplier via architecture reviews, mentoring, and distributed systems best practices.Project OMA2 -1. Led OMA v2 from POC to production, driving Flutter cross-platform architecture (Android, iOS, macOS).2. Owned DB design supporting 10+ Oracle Internal Service flows; executed data migration across 3 platforms with zero major data-loss incidents.3. Built unified Push + Pull notifications for 4–6 Oracle integrations, improving performance by ~30–40%; delivered 100% PII masking + I18n-ready support.4. Implemented encryption/decryption + public/private key token generation with zero plaintext sensitive exposure; delivered auth migration + keystore hardening.5. Shipped Debug + Log Sync, reducing troubleshooting time by ~40–50%; owned lifecycle (dev, testing, integrations, release) across 3+ stakeholder groups.Project LLM/AI -1. Built Python POCs integrating GPT-4.1, Grok-4, Cohere with OCI Autonomous DB (Property Graph) for identity analytics.2. Combined graph relationships with LLM reasoning for access reviews; automated ingestion of OCI IAM policies, users, and compartment hierarchies.3. Prototyped detection of risky access patterns, privilege relationships, and policy gaps; presented tradeoffs and production considerations to guide roadmap.
