Abhishek Pandey — Senior Software Engineer

Senior Software Engineer at Oracle with 6+ years of experience architecting hyper-scalable distributed systems, AI-powered developer platforms, and cloud-native solutions that deliver measurable business impact. I specialise in platform engineering, multi-cloud architecture, and AI/ML integration—building systems that handle 1M+ daily transactions with 99.9% uptime. What I Do: *At Oracle, I design and develop mission-critical systems for the Financial Services Analytical Application (OFSAA). I architected a universal Java platform achieving 100% compatibility across Tomcat, WebLogic, and WebSphere with seamless Java 8-21 support—cutting maintenance overhead by 60% and enabling zero-downtime deployments across diverse enterprise environments. *I spearheaded the integration of multi-model AI (GPT-4, Claude, Grok, Claude) into Code Assist with enterprise SSO, reducing inference latency by 45% and transforming developer productivity. This work demonstrates my passion for pushing the boundaries of AI-assisted development tools while maintaining enterprise-grade security and performance. My Impact: *Transformed a monolithic enterprise application into 50+ cloud-native microservices handling 1M+ transactions/day with 99.9% uptime *Reduced system latency by 70% through database optimisation, Redis caching, JVM tuning, and async processing pipelines *Saved $50K+ annually by building custom deployment automation that reduced installation time from 4 hours to 30 minutes Beyond Work: I'm passionate about open-source innovation and have built several side projects including a local AI cluster system with multi-agent orchestration, a private AI infrastructure platform running entirely on local hardware, and a comprehensive web security scanner with OWASP-focused vulnerability assessment. These projects reflect my continuous learning mindset and commitment to staying ahead of emerging technologies. Technical Expertise: Platform Engineering | AI/ML Integration (OpenAI, Claude, Grok) | Multi-Cloud Architecture (AWS, OCI) | Microservices & Event-Driven Systems | Kubernetes & Docker | Performance Optimization | Enterprise Security (OAuth2, SAML, JWT, SSO) | Java & Spring Boot | Apache Kafka | Redis | PostgreSQL | CI/CD & DevOps What Drives Me: I'm driven by solving complex engineering challenges that have real business impact. Whether it's architecting systems that scale to millions of users, optimizing performance to save costs, or integrating cutting-edge AI capabilities, I approach every problem with a focus on scalability, reliability, and security.

Building and operating production backend services on Oracle OFSAA — a financial analytics platform processing 1M+ daily transactions for enterprise banking clients.
Own 4 core Spring Boot microservices (transaction processing, audit logging, reporting, notification dispatch) handling 300K+ daily transactions at 99.9% uptime.
Reduced p99 API latency from 2,400ms to 180ms (93% improvement) through JVM profiling, HikariCP connection pool tuning, N+1 Hibernate query fixes, and Redis caching.
Built a Kafka event pipeline (12 partitions, 1M+ events/day) with DLQ retry, idempotency keys, and thread-safe consumer isolation — reducing duplicate errors by 40%.
Rebuilt the team deployment pipeline (2 hrs → 15 min) using GitLab CI/CD + Helm + Kubernetes; adopted by 6 other teams, saving $50K+/year in licensing.
Eliminated a concurrent write race condition using ConcurrentHashMap + thread-local accumulators — dropped data error rate from 0.4% to 0%.
Built observability stack (Prometheus, Grafana, ELK) adopted org-wide; cut incident MTTD from ~40 minutes to under 10 minutes.
Primary on-call responder for owned services; resolved 15+ P1 incidents with documented postmortems driving team-wide reliability improvements.
Mentored 3 junior engineers over 18 months; introduced PR review checklist that reduced post-merge defect rate by 25%.
