My full experience
2023 Dec - Present · Senior Full‑Stack Developer · CodeMarks Enterprises, Bangalore
At CodeMarks Enterprises, I lead the design and development of production‑grade SaaS platforms using Django, Node.js, React, Next.js and PostgreSQL. I drove the shift to a microservices architecture on AWS and Docker, cutting deployment times by around 40% and reducing infra costs by roughly 25% while improving overall system reliability.
I collaborate closely with product and mobile teams, contributing shared APIs and Flutter components that keep web and app experiences consistent across platforms. Beyond shipping features, I run code reviews and performance tuning sessions that have significantly improved maintainability, security and app responsiveness in production.
Zunofy – Borderless payments infrastructure (Internal Product · CodeMarks Enterprises)
At Zunofy, I architected the core payment infrastructure and backend systems for a next-generation borderless fintech platform focused on zero-fee, cross-border money transfers. The platform enables users to hold, exchange and transact seamlessly across 35+ currencies with virtual IBANs, zero FX markups, and regulatory compliance (KYC/AML) built into every layer.
I designed and shipped the multi-currency account system, payment rails, card integrations, and backend —all built on go lang, PostgreSQL and AWS microservices. The platform now serves digital nomads, freelancers and small businesses across 100+ countries, processing cross-border transfers with near-instant settlement times and full transparency on fees and exchange rates.
2022 Jan – 2023 Nov · Lead Engineer · “Wealth I/O”, Virginia (Remote)
As Lead Engineer at Wealth I/O, where I architected and shipped a suite of 8+ AI‑powered tools for lead generation, data processing and intelligent follow‑ups for financial advisors. The platform combined FastAPI, LangChain and MongoDB to let an in‑house AI agent (“Anna”) analyze prospect financial data and surface actionable insights from natural‑language queries.
I owned end‑to‑end delivery for multiple products, including lead capture funnels, Nuxt.js/TypeScript frontends, and Stripe‑backed subscription billing built with Nest.js. I also managed SOC 2‑aligned infrastructure and production support for thousands of active users, balancing rapid feature delivery with reliability and compliance.
2020 Jun – 2021 Dec · FullStack Developer · EPYC ThoughtWorks Pvt. Ltd, New Delhi
At EPYC, I focused on high‑performance frontends using Nuxt.js, Vue and TypeScript, leveraging SSR, smart component design and mixins for fast, SEO‑friendly apps. I integrated services like GitHub, AWS and Google Analytics to extend platform capabilities and improve observability across products.
I also implemented advanced platform features such as Algolia‑powered search, Mapbox‑based mapping, and custom domain + automatic SSL provisioning using Node.js and Nginx Lua scripts. On the infra side, I worked with Grafana, Prometheus, k6 and JMeter to monitor, load test and harden applications running at scale.
