About Me

My journey from frontend development to backend specialization

I'm a Software Developer with 2+ years of experience, currently transitioning into backend specialization. My journey began in frontend development, but I've discovered my passion lies in designing and building scalable, robust backend systemsthat power seamless user experiences.

At AlgoAcharya (fintech startup), I contributed to algorithmic trading platforms, working across the stack — from crafting responsive dashboards to optimizing APIs and database queries for performance. This hands-on work gave me a solid understanding of how frontend and backend connect in real-world systems.

Recently, I've been expanding my skills into backend engineering with Java (Spring Boot), Go, and Docker, alongside deep dives into system design, DBMS, operating systems and computer networks. I'm also exploring algorithmic trading with Python, pandas, and risk management strategies, combining my tech skills with my passion for financial systems.

Currently Focusing On

• Building backend APIs with Java (Spring Boot) and Node.js (Express)

• Exploring distributed systems and microservices architecture

• Experimenting with algorithmic trading strategies using Python and pandas

• Strengthening CS fundamentals (OS, DBMS, CN, DSA)

• Deploying apps with Docker and exploring cloud-native workflows
