I build backend systems and AI infrastructure.

Distributed systems, developer tooling, and production-grade AI applications.

Flagship repos are the fastest path to judge engineering depth — source, tests, ADRs, and case studies on this site stay aligned via shared catalog data.

flagship · ai & distributed systems

VoxForge2025–26

Voice AI stacks split across transports and lack production operability (eval, replay, deploy).

Open-source voice AI infrastructure platform with one unified pipeline, RAG, evaluation, replay, and one-command HTTPS deployment.

my role · Solo design and implementation — architecture through HTTPS deploy, tests, and docs.

hard part · One VoicePipelineService for WebSocket, REST, and LiveKit without duplicating agent and RAG logic.

BugSathi2026

Bug reports lack evidence and teams cannot audit how recordings become AI-written reports.

Local-first, AI-native bug reporting platform — screen recording upload, ffmpeg frame extraction, AI-drafted reports, shareable links, and an ordered Kafka pipeline in Go.

my role · End-to-end Go systems build — API, workers, Kafka pipeline, observability, ADRs.

hard part · Ordered, idempotent media + AI pipeline per recording under Kafka replay and failure.

SignalMine2025–26

Unstructured forum and issue threads hide product and market signals; manual synthesis is not reproducible.

Source-agnostic pipeline turning GitHub and Reddit discussions into schema-validated market intelligence.

my role · Pipeline design, collectors, normalizer, schema-bound extraction, evaluation harness, and FastAPI service.

hard part · Reliable LLM extraction with JSON Schema contracts and golden-dataset regression scoring.

PaintCRM2025

Dealers need sub-minute wall previews and lead capture on unreliable shop-floor networks.

Full-stack paint dealer platform — upload a room photo, preview 63 catalog shades on walls in under 60 seconds, capture leads, and run quotes, orders, inventory, and receivables offline-first.

my role · Full-stack product build — offline-first UX, Express API, ledger integrity, deploy.

hard part · Offline-first CRM sync with server-authoritative financial data.

upcoming

Arden2026+

Teams need a scheduler that survives worker crashes without double execution or lost jobs.

Upcoming distributed job scheduler and execution engine in Go — Postgres-backed leasing, fencing, and observability.

my role · Planned — distributed job engine in Go (design phase; not yet implemented).

hard part · Postgres as source of truth with leasing, fencing tokens, heartbeats, and fair retry/DLQ semantics.

Status: upcoming · not production-ready

writing · engineering notes

Long-form notes grounded in repos I built — not framework tutorials. Published articles will link here; until then, these topics match active implementation work on GitHub and case studies on this site.

in progress

  • Building a real-time voice AI infrastructure platform
  • Designing event-driven services in Go and Kafka
  • Building reliable LLM extraction pipelines
  • Distributed systems correctness: leases, fencing, and recovery
  • Implementing observability in production applications
  • RAG in production: chunking and grounding tradeoffs
  • Per-turn evaluation as a deployment gate for voice agents
