A service business needed one place to collect onboarding details, manage organizations, handle support requests, expose customer documents, and keep internal admin work from turning into scattered email threads.

Built a Go-backed customer panel with organization-aware routing, onboarding steps, billing handoff, support tickets, document access, admin queues, and frontend permission helpers. Added deployment validation, frontend smoke tests, and cache-busted static assets so customer-facing changes ship predictably.

Turned the managed-website service into an operational system: signup, intake, support, and internal follow-up now share one workflow instead of relying on manual coordination.

Field-oriented work needs fast capture, durable state, and clear handoff between the person doing the work and the backend system that tracks progress, status, and history.

Built a Kotlin-first mobile workflow backed by Go services and PostgreSQL routines. Kept the domain model explicit so jobs, statuses, and transitions can be reasoned about across app and server boundaries.

Created a practical pattern for mobile-first operational software: the phone becomes the front line for capture while backend services preserve the source of truth.

Managed websites need repeatable technical checks without turning every audit into a manual browser session: metadata, page structure, broken links, indexability, and deployment regressions all need a consistent review path.

Built Go-based crawl and reporting tooling with a lightweight browser UI, shell automation, and static output paths. The crawler focuses on repeatable checks that can be rerun after content or deployment changes.

Reduced technical SEO review from an ad hoc checklist to a reusable workflow that supports maintenance, launch checks, and client-site quality control.

Sensitive document workflows need a safer structure than shared drives or email attachments: access, ownership, family sharing, and lifecycle state all have to be modeled carefully.

Built a React and Go platform around secure document storage, account-level workflows, and controlled sharing. Treated permissions and data boundaries as product features instead of afterthoughts.

Produced a private MVP architecture for high-trust document workflows where the main engineering risk is not rendering pages, but protecting state transitions and access paths.

A real-time strategy prototype needed synchronized multiplayer without trusting every client input, while keeping the simulation deterministic enough for fair wave-spawn gameplay.

Designed a Godot 4 multiplayer architecture around deterministic lockstep updates, Steamworks multiplayer integration, commit-reveal input validation, polymorphic unit behavior, and automated GUT coverage for gameplay systems.

Established a testable multiplayer foundation where fairness, determinism, and unit-system flexibility are explicit constraints instead of late-stage patches.

Trading and analytics experiments require repeatable data collection, derived signals, backtesting or review surfaces, and guardrails so automation does not become an opaque black box.

Built Python-heavy tracking and bot tooling with web output, containerized runtime paths, and explicit separation between data collection, analysis, and execution-facing logic.

Created a reusable pattern for private analytics systems: collect consistently, inspect the intermediate state, and keep execution decisions isolated from raw scraping or signal generation.

Building a full 3D isometric action-RPG that runs smoothly in web browsers—including mobile devices—without native code or plugins.

Built with Three.js using a chunk-based streaming architecture—only loading and updating entities within the player's active 3x3 chunk grid. Optimized GLTF assets to 500-2k triangles per model. Implemented instanced rendering for repeated objects, frustum culling, and draw call batching to keep GPU overhead minimal.

Achieved consistent 60 FPS target on desktop and mobile browsers with smooth gameplay and responsive controls.

Initial multiplayer implementation sent complete world state to every connected player on each tick, causing bandwidth to scale linearly with player count and limiting concurrent sessions.

Rewrote the Go server to track per-player entity snapshots and transmit only changed fields. Added GZIP compression with pooled writers to eliminate allocation overhead. Prioritized updates by proximity—nearby entities update at 20Hz, distant entities at 5Hz.

Reduced per-player bandwidth by ~80%, increasing theoretical player capacity from ~50 to ~250 concurrent players on the same server hardware.

Naïve collision detection checked every entity against every other entity—O(n²) complexity that degraded rapidly as world population grew beyond 100 entities.

Implemented a spatial hash grid partitioning entities into 50-unit cells. Collision queries now only check entities in adjacent cells. Added separate tracking for movable vs static entities to skip unnecessary recalculations.

Collision detection dropped from O(n²) to O(n), supporting 500+ simultaneous entities with sub-millisecond query times.

Needed thousands of unique items without hand-crafting each one, while ensuring loot felt rewarding at every level and preventing stat inflation from breaking balance.

Built a composable item generator with base types, rarity tiers, and affix pools. Stats scale via formulas tied to item level and rarity multipliers. Rarity distribution uses weighted random selection (Common 50%, Rare 30%, Epic 15%, Legendary 5%).

System generates 10,000+ unique item combinations. Level 1 and level 50 items feel proportionally powerful without manual tuning per tier.

Party features (health bars, positions, shared XP) required frequent updates, but broadcasting to all connected players wasted bandwidth and leaked information.

Implemented party-scoped message channels. Party state changes broadcast only to party members via ID lookup. Added leader transfer on disconnect and automatic disband when empty.

Party updates use <1% of total bandwidth. Supports unlimited concurrent parties with zero cross-party data leakage.
