About

I have been working for the last 8 years in multiple organisations like Capgemini, Fynd, Finoux Solutions, Network Intelligence India and have built and designed systems that have scaled to handle millions of users. After graduating, I joined Capgemini where I worked for big insurance client on their tool for 1 year. After serving a short time there, I joined a race car at Finoux Solutions where I worked solo on the Internet Banking application which was used by a quarter million user base. I learned the ropes of the trade and worked with some amazing colleagues. I worked with clients like Saraswat Bank, SBI Mutual Funds and Northern Trust. I moved to NII for a short 5 months and joined literally a rocket-ship called Fynd. This is where I learnt and worked with the best colleagues, managers and tech leads. I worked on very high impact features and was involved in helping the company grow its revenue by millions. I also worked on Jio projects where we developed systems to handle millions of order on a daily basis. I also graduated from SDE-2 to SDE-3 but left to test new waters. I worked on some interesting stuff at Signeasy that I hadn't tried before like Apache Airflow, Kubernetes, AWS API Gateway, AWS Lambda etc. After working for some time I contemplated and decided to switch. Currently, I'm working with Airbase on the Expense Management team where I help thousands of employees get their reimbursements on time and accurately. I work in a close-knit team on challenging and important projects. Our platform handles billions of dollars worth of transactions yearly. Tech Stack worked over the years: Python [Flask, Django, Sanic, FastAPI], MySQL, PostgreSQL, MongoDB, Redis, Kafka, Celery, Apache Airflow, AWS [S3, RDS, Lambda, API Gateway, EC2], Docker, Kubernetes, Prometheus, Grafana, Jaeger, New Relic, Datadog, Sentry, ELK, Gunicorn, Nginx, Angular, Ionic Schedule a meeting with me: https://cal.com/sagar-manjare
