In-depth understanding of DevOps practices, CI/CD pipelines, and infrastructure automation. Demonstrated effective interpersonal, verbal and written communication skills. Here is some highlights from a TEKsystems former that he showcased on his Linkedin Profile. * Led the architectural and technical design as a two-engineer team, launching a complex scheduling product from conception to production, now serving 17,000+ monthly users on a Rust, GraphQL, and React stack. * Contributed to a metadata-driven backend framework (YAML/CSV Rust/SQL/GraphQL codegen), where schemas, CTE-based queries, and seed SQL are generated from declarative configs-dramatically accelerating schema evolution and reducing boilerplate. * Designed, built, and shipped a fullstack scheduling platform in 9 months that handles tens of thousands of schedules, supports role-based access control, and reduces operational workflow times by 80%+. * Architected and shipped a Rust based sync service using procedural macros and a custom semantic-matching DSL to map complex FHIR-like MongoDB documents to normalized SQL tables-safely syncing 100k+ documents into PostgreSQL via Kafka consumers and direct DB pipelines to establish a single source of truth. * Built a reusable GraphQL filter engine used across the application that composes nested filters, sorting, and pagination into type-safe JSON structures eliminating repetitive query wiring and enabling highly composable filtering on the frontend. * Collaborating with the security team to implement a full-stack OIDC/PKCE authentication flow in Rust and TypeScript to strengthen platform security and user authorization. * Providing guidance on Jira points estimations and React best practices on the development team. * Replaced Redux with a Jotai + Apollo state architecture, enabling complex UI interactions, reducing global state complexity, and significantly increasing team development velocity. * Designed and built advanced scheduling UX features such as drag-and-drop personnel assignment, calendar filtering, time-range conflict checks, and role-aware views surfacing availability constraints directly in the calendar experience. Skills React, C#, Python, Rust, graphql Top Skills Details React,C#,Python Additional Skills & Qualifications I had a reset meeting with Rachna regarding her open Full stack developer need. She had a candidate that they made an offer to and that person had a visa issue and they were not able to move forward. Nothing has really changed regarding the stack or the need. They have had several people take their test and most are just using AI and not understanding the reason why the code is the way that it is. They are not opening the read me files and doing the research that is needed to accomplish the tasks logically. most of what they are testing is front end. React. They are using cutting edge technology and wanting someone that is adaptable. Someone that is wanting to learn and grow with the company. Just because someone has 20 years of experience, doesnt mean they are a Sr developer. Willing to look at more mid level candidates. She had 2 interns that came in last year and they are great. We need someone over that experience level, but need builders and not just people that have been supporting an environment and are fixing bugs. Frontend is React and the backend is Rust, but open that is something that someone can learn. Need to be able to develop in a cloud native environment. 100-150K, but really looking to stay under 130K. Someone with excitement that wants to learn and grow. I would like to turn the heat back up. Biggest challenge is that people don't want to work onsite 5 days a week and we need to find someone that will thrive in that type of an environment. Getting a req back in the system and seeing if we can make an impact. She is frustrated that she hasnt found anyone yet, but she knows that she is picky, but what she is asking for isnt unrealistic.
