About

🔹 About Me 🔹 4+ years of experience in software development Hello, I'm Abhinandan, a passionate Software Development Engineer focused on building robust, scalable systems. I love turning complex ideas into reliable products and driving positive change in the tech industry. 🛠️ Professional Journey 🛠️ 🚀 Walmart (Jan 2024 - Present) I own products end to end — from initial build to scaling and re-architecture. I evolved a monolithic finance forecasting dashboard into a decoupled, config-driven platform (PostgreSQL, Redis) and re-architected an agentic AI assistant into clean microservices with LLMs, centralized config management, and full observability (OpenTelemetry, Prometheus, Grafana). I also optimized read-heavy insight pipelines from minutes to seconds and built config-driven Airflow ETL frameworks and Dockerized CI/CD on Kubernetes. 🚀 Cogoport (Jan 2022 - Dec 2023) Drove legacy system migration and resilient backend development, building RESTful APIs with Python, Java, Ruby on Rails, FastAPI, and PostgreSQL. 🎓 IIIT-Allahabad Alumnus (Post Grad, 2023) Focused on AI/ML, with notable work in tampered image detection. 🚀 Tech Mahindra (May '19 - Sep '20) Oversaw AT&T product availability with 95% issue-resolution success and a 15% efficiency gain via SQL optimizations. 🚀 Key Skills 🚀 Python | Microservices | System Design | Apache Airflow | Docker | Kubernetes | PostgreSQL | Redis | Agentic AI & LLMs | FastAPI | AWS | CI/CD 🌐 Let's Connect 🌐 I'm an enthusiastic learner motivated to build cutting-edge solutions in collaborative teams.

Work experience

Software Engineer - II at Walmart Global Tech India, Feb 2024 - Present · 2 yrs 8 mos, Bengaluru, Karnataka, India, • Own products end to end: built a financial forecasting platform, evolving it from a single Dash/Python dashboard into a scalable, decoupled system (data, middleware, frontend) that pre-computes YoY, 2-year stack, AUR, and dollar-delta metrics to replace costly real-time computation. • Built a config-driven card system where a single YAML file generates a new dashboard, backed by PostgreSQL and Redis caching to cut load times from seconds to sub-second. • Diagnosed and eliminated a read-path bottleneck across paginated PowerBI insight reports using bulk reads, request sanitization, and caching, reducing response times from minutes to seconds even on cold cache. • Designed and shipped personalized insights, letting users choose their reporting hierarchy (SBU, department, channel, subchannel), including the underlying data models. • Built and owned an agentic AI assistant that analyzes, detects anomalies in, and forecasts business data using a 3-tier agent framework over Confluence, PowerBI, and BigQuery. • Re-architected the AI platform from a complex monolith into clean microservices (API, agents, email) and integrated centralized config management for instant, zero-deployment production updates. • Instrumented full observability with OpenTelemetry, Prometheus, and Grafana, and built an admin dashboard tracking usage, job status, and per-agent LLM cost. • Created a config-driven Airflow DAG framework that reduced DAG creation from 80+ lines to 5, promoting reusability across ETL pipelines ingesting sales and Moody's macro-economic data. • Established Dockerized CI/CD pipelines on Kubernetes across multiple services in production, and packaged a reusable CI/CD "starter kit" to fast-track new repositories to production-ready pipelines.

Software Development Engineer - 1 at Cogoport, Jul 2023 - Dec 2023 · 6 mos, Gurugram, Haryana, India, • Crafted RESTful APIs using Java, Python, FastAPI and Ruby on Rails, including seamless migration of legacy systems. • Contributed to the design of core backend APIs for various products and led the development of REST APIs, contributing to their foundational structure. • Orchestrated a targeted database optimization initiative, yielding substantial improvements in API performance, data querying, streamlined data processing and achieved runtime reductions of up to 50% for select APIs. • Created various email templates for customers to provide real-time shipment tracking updates and essential documents.

Research And Teaching Assistant at Indian Institute Of Information Technology Allahabad, Jul 2021 - Jul 2023 · 2 yrs 1 mo, Prayagraj, Uttar Pradesh, India, • Demonstrated proficiency in Python to extensively research on tampered image detection using transformers, resulting in the acceptance of the thesis and research paper. • Facilitated tutorial classes, orchestrating interactive laboratory sessions to adeptly transfer technical expertise and skills to students

Software Engineer at Tech Mahindra, May 2019 - Sep 2020 · 1 yr 5 mos, Noida, Uttar Pradesh, India, • Oversaw AT&T product availability through supply chain management, ensuring accessibility as per operational requirements. • Provided strategic technological assistance in alignment with the company’s goals and specific requirements, contributing to the overall success of the organization. • Employed effective resolution of customer concerns with a success rate of 95%, delivering solutions. • Implemented optimizations in data handling processes, realizing a substantial 15% increase in overall efficiency. • Applied advanced SQL and MySQL to streamline data operations and enhance organizational productivity
