SUMMARY
Backend developer focused on Go, concurrent systems, and backend architecture. Built independent products and backend
services using Go, PostgreSQL, SQLite, WebSockets, REST APIs, Docker, goroutines, channels, and worker pools. Experience
building concurrent network services, authentication systems, data-processing pipelines, and AI-assisted developer tools.
TECHNICAL SKILLS
Languages: Go, SQL
Backend: REST APIs, gRPC, WebSockets, net/http, authentication, sessions
Databases: PostgreSQL, SQLite, pgx
Concurrency: Goroutines, channels, worker pools, fan-out/fan-in, Mutex/RWMutex, context
Tools / Networking: Docker, Git, HTTP, DNS, TLS

SELECTED PROJECTS
Ground Truth - Developer Problem Intelligence Platform
Independent Product
• Built a search and analysis platform aggregating thousands of GitHub issues, Stack Overflow questions, and technical
discussions to identify recurring engineering problems.
• Implemented cross-source problem validation, trend detection, evidence-backed reports, technology analysis, and
repository-level analysis.
• Designed results around traceable evidence linking findings to original technical discussions rather than relying solely on
model-generated answers.
urlwatch - Concurrent URL Monitoring Service
Go | SQLite | net/http
• Built a bounded worker pool backed by a buffered Go channel for concurrent background processing.
• Implemented per-task fan-out/fan-in with goroutines and channels to execute DNS, HTTP, and TLS checks concurrently.
• Added stalled-task detection and automatic recovery of unfinished work after process restarts.
auth-hub - Realtime Authentication Service
Go | PostgreSQL | WebSockets
• Built authentication with PostgreSQL, bcrypt password hashing, cookie-based sessions, and protected HTTP routes.
• Designed a WebSocket hub supporting multiple connections per user, realtime activity broadcasting, online-user tracking,
and a bounded 100-entry activity log.
• Refactored the application into auth, database, handlers, models, and socket packages while propagating context.Context
through database and WebSocket operations.
grpc-user-service - gRPC User Service
Go | gRPC | SQLite
• Built a full CRUD service over gRPC (create, read, update, delete, paginated list) with server and client generated from a
single .proto definition.
• Designed a layered architecture where the gRPC handler is the only layer aware of generated protobuf types, and the
service layer depends on a repository interface rather than a concrete database - Postgres could replace SQLite without
touching business logic.
Forge - AI Website Generation System
Independent Product
• Built a system that generates complete websites from natural-language product descriptions, including page structure,
content, visual theme, and reusable components.
• Developed a component-based generation pipeline with automated quality checks across layouts and themes.
• Built a library of 48 components covering 8 product niches, with generated sites averaging approximately 30 seconds to
assemble.
