Full-stack software engineer with a strong backend foundation, building production-ready AI and LLM-powered features end to end. I work across backend, APIs, and data pipelines to turn AI capabilities into reliable, user-facing systems. Experience includes supporting LLM workflows such as data preparation, prompt experimentation, evaluation, and integrating model inference into full-stack applications. Currently open to fullstack or AI-focused roles centered on real, scalable products.

Employment History

Senior Software Engineer at Iflexion 2024 - 2026
• Designed production inference services that handled 1M+ monthly interactions, exposing standardized REST endpoints and SDKs for web/mobile integration. • Implemented temporal attention and motion-aware modules for video generation; reduced artifacts and improved output realism across core use cases. • Built GPU-optimized, containerized pipelines on Kubernetes with autoscaling and request batching; cut p95 latency by 38% under peak load. • Applied model compression (quantization, pruning) and precision tuning to lower GPU hours while maintaining quality and throughput targets. • Stood up end-to-end observability with Prometheus/Grafana, structured logging, and alerting tied to SLOs; enabled proactive capacity tuning and rapid incident response. • Established auth, rate limiting, and usage metering for multi-tenant clients; aligned IAM policies and service boundaries with least-privilege access.
Senior Software Engineer at SoftServe 2022 - 2024
• Architected a chatbot backend using Django APIs and background workers to orchestrate intents, tool usage, and secure data retrieval from core platforms. • Trained and fine-tuned NLU models (BERT/TensorFlow) with domain corpora; increased intent coverage and contextual accuracy for fitness workflows. • Built a curated knowledge base and retrieval layer to standardize answers across policies, schedules, and FAQs; improved response consistency. • Introduced analytics pipelines for dialog events, abandonment, and CSAT; informed iterative model and UX improvements that reduced support load. • Implemented monitoring, feature flags, and safe rollouts for model updates; maintained uptime during peak traffic and seasonal campaigns. • Hardened security and compliance with input validation, secret rotation, and IAM scoping across environments.
Software Engineer at Oxygen Technologies 2020 - 2022
• Led backend development in Python/PHP (Flask, Django) to support global campaigns serving millions of users with strict latency requirements. • Decomposed C++ monolith components into containerized microservices on AWS EKS; improved release cadence and fault isolation. • Designed REST and GraphQL endpoints to unify data exchange with third-party providers; reduced integration complexity for client apps. • Migrated infrastructure to AWS (EC2, RDS, IAM) with IaC patterns and environment parity; improved stability and security baselines. • Added robust error handling, circuit breakers, and health checks; increased resilience and maintained campaign uptime during global events.
Full Stack Developer at Interactive 2018 - 2020
• Developed RESTful services and background jobs to support high-traffic features and integrations with third-party providers. • Built React/Redux TypeScript frontends with lazy loading and API caching to improve UX and render performance. • Integrated payments, analytics, and authentication providers; standardized webhook handling and retry policies. • Containerized deployments on Docker and GCP; optimized CI/CD to shorten release cycles and reduce rollback risk.
Software Development Intern at Burgi Technologies 2017 - 2017
• Built real-time internal dashboards using Node.js and MongoDB for business performance visualization. • Developed unit tests and debugged backend services, contributing to higher code quality. • Assisted in CI/CD adoption, gaining exposure to agile practices and cloudnative tooling.
