Work Experience
Senior Engineer | Core Maintainer (Founding Team)
Mathesar
- Worked as a founding engineer helping build and maintain Mathesar, an open source Airtable alternative and spreadsheet-like interface over PostgreSQL. Took the product from 0 to 1, and maintained it through alpha, beta, and public releases.
- Maintained Mathesar as a primary core team member, identifying and building features, reviewing community pull requests, interacting with users, orchestrating release cycles, and authoring contribution guidelines.
- Led the full-stack development of core features, including database provisioning, core spreadsheet UI over PostgreSQL tables, publicly shareable table-backed form builder, data explorer that queries user DBs via UI, including joins.
- Established the front-end architecture from scratch, including the store system, sync between user-configured databases and UI, the in-house component library, and the design system.
- Spearheaded Mathesar's permission system to integrate directly with PostgreSQL roles, centralizing authorization logic to ensure granular, database-level security for all users.
- Architected deployment workflows, designed Docker-based setups, built a UV-based native installation method that enabled dependency-free setups across Linux, macOS, and Windows, and configured CI/CD pipelines.
- Represented the organization as a speaker at PGConf India 2024 and ChennaiFOSS 2.0, presenting on Making PostgreSQL Accessible, driving significant developer engagement and user adoption.
- Mentored global contributors as a primary mentor for Google Summer of Code (GSoC), guiding the architecture and implementation of features like JSON Support, significantly expanding Mathesar's data handling capabilities.
Senior Engineer
Falabella
- Contributed to and maintained multi-tenanted core microservices of the eCommerce platform of Falabella, South America's largest retailer, and its subsidiary, Sodimac.
- Built v2 API endpoints of the product-catalog and pricing microservices with additional features for reseller integration, and migrated the site to the new endpoints with zero downtime and zero incidents.
- Architected services to handle 6,000 requests per second on average, which effortlessly scaled up to 15,000 requests per second during major sale events.
- Headed the development of an in-house ratings and reviews system by managing and mentoring a team of two engineers throughout the full development lifecycle.
- Reviewed architectural designs and code, led cross-team communications, coordinated with business teams, conducted technical interviews, and prepared proof of concepts for new systems.
- Built and maintained the data platform used by business teams and sellers to safely update pricing and product data in production.
- Architected and built versioning and auditing capabilities for product data, automated approval process workflows for updates, conflict tracking between staged and production data, SSO, user management, and RBAC.
- Provided critical technical support during high-load sales events, ensuring immediate recovery for data sanity issues.
Co-Founder | Full-stack Developer
Stealth Startup
- Developed the leading user-facing service, including the front end, REST APIs, database schema, and service orchestration, single-handedly for my own startup, offering a distributed log management solution for SMBs.
- Architected a complex data pipeline with capabilities for collecting, parsing, indexing, searching, alerting, and archiving logs from operating systems, databases, and web servers.
- Owned the full product lifecycle, from initial requirement analysis, building an MVP, securing the first users for the on-premise solution, getting it production-ready, to scaling the product.
Member Technical Staff
Zoho
- Developed a rule-based event correlation engine for ManageEngine EventLog Analyzer, an enterprise log management and SIEM solution, which contributed to an increase in revenue by 32%.
- Spearheaded and executed legacy code migration projects to modernize the application stack, from JSP to Ember.js and REST APIs.
- Mentored and managed a team of four junior engineers and successfully shipped key features as a team, such as license management, automated Windows device discovery, and role-based access management.
- Spoke at the IDC IT Security Summit in Oman in 2018. Conducted 1-on-1 user sessions at the ManageEngine User Conference in New York in 2017.
Experience
Mathesar
https://github.com/mathesar-foundation/mathesar/As a founding team member, I architected Mathesar from a 0-to-1 MVP and scaled it into a mature open-source platform that has received over $ 3 million in donations to date.
I am a core maintainer who built the spreadsheet layout, the form builder, PostgreSQL native RBAC, owned the entire front-end stack, engineered APIs and SQL layer functions, architected the infrastructure and installation methods, shaped the product roadmap, and managed community contributions.
AI Agentic Workflow (n8n) for Clinic Appointment Scheduling
https://gist.github.com/pavish/2e75cf2479517008557eab8555d29a97I built the entire workflow from scratch and successfully deployed it to production. I used Claude as a code companion to write up the workflow, and DeepSeek for the AI agents since the client wanted low-cost APIs. The system accepts any OpenAPI-compatible APIs for the large language models (LLMs). The PostgreSQL database is hosted using Supabase. I also implemented a small admin dashboard and management view in React and Next.js for internal use.
