Mid-level Full-Stack Software Engineer specializing in cybersecurity and AI-enabled web apps

Columbia, MD3y exp

“Frontend engineer with experience building user-facing React/TypeScript features in startup and security contexts, including live-stream clipping for collegiate sports video and organization-relationship graph visualizations. Has hands-on experience with Redux state management, CSS/UI debugging, and adapting visualization libraries like Sigma to product needs.”

“Backend engineer specializing in event-driven/serverless systems and Python/FastAPI APIs. Built a scalable PDF-to-structured-data pipeline on AWS (S3, Lambda, Step Functions, Textract, DynamoDB, SNS) with strong observability (p50/p90/p99) and reliability patterns (idempotency, retries/DLQs), and has led zero-downtime migrations using feature flags, dual writes, and incremental rollouts.”

“Robotics competition (ABU Robocon) team member who programmed two robots for a rugby-style game, integrating IoT sensors and real-time decision-making. Implemented low-latency, secure inter-robot communication by moving from Bluetooth to ESP8266/NodeMCU WiFi (with Bluetooth as backup) and used OpenCV plus CNN training workflows for vision-related tasks; no practical ROS/ROS2 experience.”

“Senior frontend developer with end-to-end ownership of modernizing a legacy Laravel/PHP product into a Next.js 14 + React + TypeScript stack, using TurboRepo for incremental integration. Emphasizes quality and scale through unit testing, Datadog monitoring, and performance-focused UI work (dashboards with charts/usage analytics, minimizing re-renders).”

“Unity game developer who implemented a blockchain/NFT feature in a mid-core football game, including wallet connection via an external web portal and backend coordination for trading player skins/outfits. Has cloud-focused networking experience (AWS/Firebase) primarily for turn-based multiplayer systems and uses Copilot/VS Code to accelerate boilerplate and architecture exploration.”

“Junior Software Developer with a master’s in Interactive Media who studied XR and built a personal VR space. Already uses AI tooling (Windsurf Cascade) in day-to-day development for feature support and debugging, and is seeking a more structured, mentored environment while ramping into Unity/Meta Quest work.”

“Frontend engineer who led an end-to-end dashboard web app build, starting from UI sketches and user stories through design documentation and a proof-of-concept to align stakeholders. Uses a modern React/TypeScript stack (TanStack Query/Table/Form, shadcn/ui, Tailwind) with Zod validation, ESLint + CodeRabbit PR checks, and Vercel Analytics for performance monitoring.”

“Frontend engineer who has led customer-facing React + TypeScript products end-to-end, building complex dashboards with robust async state patterns (caching, deduping, cancellation, optimistic updates) and strong quality practices (TypeScript standards, layered testing, production monitoring). Experienced modernizing inherited codebases through modularization and performance work (code splitting/memoization) while aligning stakeholders and shipping safely via feature flags and staged rollouts.”

“Frontend engineer with ~6 years of experience delivering SEO- and performance-sensitive web apps (e.g., an automobile sales platform built with Next.js SSR) and complex React+TypeScript dashboards for energy management/heat pump scheduling. Has handled real-time data challenges by integrating MQTT, and combines hands-on frontend ownership with Agile team coordination (standups, task assignment, client demos, requirements).”

“Backend-focused engineer who built an academic AI voice assistant with a Python microservice-style backend (speech recognition, spaCy-based NLP, and Kafka-driven automation) optimized to sub-500ms latency. Also has Sodexo internship experience deploying containerized services across Kubernetes/AWS ECS/Azure using ArgoCD GitOps, including solving config drift and secret-management challenges and supporting cloud-to-on-prem migrations with blue-green rollouts.”

“Full-stack engineer from Clairvoyant who led end-to-end delivery of a cloud-native, event-driven platform: Spring Boot microservices + Kafka real-time streams with an Angular UI, migrated and containerized on AWS, and automated CI/CD with Jenkins/Maven/Git.
